We have now completed a massive building import for northern Zambia. Building data in OSM enables on the ground teams access to a critical shared resource and this new data is supporting active malaria prevention programs across Zambia.</p> <p>Over the last few weeks, we’ve been working with <a href="">Akros Global Health</a>, <a href="">Ona</a>, and <a href="">USAID’s Geocenter</a> to import this massive building dataset. Akros has collected over a million buildings through mSpray, their Indoor Residual Spraying (IRS) program for malaria prevention funded by the <a href="">President’s Malaria Initiative (PMI)</a> and <a href="">Bureau for Global Health</a> at USAID. These teams need data to know where, when and what to spray. Using geospatial data enables teams to more effectively carry out spray campaigns and offer real-time monitoring of spray team logs ensuring goals are being met. This import is just the beginning for these programs as they look to leverage OSM as a shared resource for baseline data.</p> <figure class="bleed-full"> <iframe width="100%" height="550px" frameborder="0" src=",zoompan.html?access_token=pk.eyJ1IjoiZGV2c2VlZCIsImEiOiJnUi1mbkVvIn0.018aLhX0Mb0tdtaT2QNe2Q"></iframe> <figcaption>260,000 buildings across northern Zambia</figcaption> </figure> <p>This new data comes just in time for <a href="">OSM Geography Awareness Week</a>.

The site provides an easy to understand starting point for anyone looking to get more use out of satellite imagery.</p> <h3 id="planet-labs-further-outlined-their-commitment-of-60m-in-imagery-for-sustainable-development">Planet Labs further outlined their commitment of $60M in imagery for sustainable development</h3> <p>In September, Planet Labs announced their pledge of <a href="">$60M of imagery to support the UN Global Goals</a>. <a href="">Amit Kapadia</a> was on hand to showcase their first tangible result: <a href="">Open California</a>. This same platform will be used to host the next imagery release for a yet-to-be-determined developing country. This data is all available under the <a href="">CC BY-SA 4.0</a> license to allow open use by researchers and humanitarian organizations alike.</p> <h3 id="airbus-previewed-its-haps-program-which-combines-benefits-of-satellites-and-drones">Airbus previewed its HAPS program which combines benefits of satellites and drones</h3> <p>Jeremy Hale shared details on the latest advances made by the Airbus pseudo-satellite, <a href="">HAPS</a>. These devices combine the persistence (via solar power) of satellites with the real-time response of drones. These qualities make them well suited for natural disaster response and long-term monitoring of a specific areas. After more than a decade in development, operational tests have taken place across the world in the past year and we’ll soon have access to this incredible new tool.</p> <h3 id="amazon-announced-that-aws-on-landsat-served-up-500-million-requests">Amazon announced that AWS on Landsat served up 500 million requests</h3> <p><a href="">Landsat</a> data is some of the most valuable open data that the US Government provides. But without the <a href="">fast, programmatic access</a> that <a href="">AWS provides</a>, we aren’t getting the full impact. <a href="">Jed Sundwall</a> shared some stats on how fast their program has been growing and how <a href="">different organizations</a> are making use of their hosting.</p> <h3 id="continuing-the-conversation">Continuing the Conversation</h3> <figure class="align-center"> <img src="/assets/graphics/content/prose/sat-summit-conversation.jpg" alt="People talking at SatSummit" /> </figure> <p>We can only accomplish so much in one day. Here’s how you can continue the conversation about satellite use in global development:</p> <ul> <li>Read the <a href="">World Bank “Satellites in Global Development” Report</a> and hit <a href="">us</a> or <a href="">Bruno</a> up with your feedback. We’re working hard to get this open on GitHub in the near future.</li> <li>Check out the <a href="">presentations</a> and let us know what you think!</li> <li>Follow <a href="">SatSummit</a> on twitter for ongoing discussion on this topic and more info on the next event.</li> </ul> 2015-11-13T00:00:00+00:00 Development Seed Meaningful public procurement data <p class="dropcap">Quality data and analytics is of crucial importance in public procurement. It allows civil society to hold governments accountable, and allows individuals within government to ensure that the procurement is conducted in a fair, timely and cost efficient way.</p> <p>Together with the <a href="">World Bank Governance Global Practice</a> and the Mexican government, we developed a <a href="">set of dashboards</a> that explores over 500 000 federal procurement procedures. Mexico has shown great commitment to open contracting by opening up <a href="">their data</a>, but also by driving the development of these kind of tools.</p> <figure class="align-center"> <a href=""> <img src="/assets/graphics/content/prose/proc-dashboards.png" alt="The dashboard providing a summary of the Compranet data" /> </a> <figcaption>The dashboard providing a summary of the Compranet dataset</figcaption> </figure> <p>Mexico is not alone in <a href="">their efforts to improve public procurement</a>. Governments around the world are working to make their processes more transparent, efficient and inclusive. That’s why the dashboards ingest data in the <a href="">Open Contracting Data Standard</a>. Agencies reporting data in this format are able to fork the tool and adapt it so it addresses policy issues that are important to them. Whether that’s the inclusion of SMEs in the procurement process, battling corruption, or ensuring fair prices.</p> <p>The current dashboards are a pilot, capable of driving discussions around which tools governments need to understand and improve their procurement performance. The code powering the dashboards and the data processing scripts are all <a href="">available on Github</a> under an open source license. Feel free to fork them and use them for your own use case.</p> 2015-11-04T00:00:00+00:00 Development Seed Know Your Online Privacy <p class="dropcap">We believe deeply in an open and secure internet, and try to use services that respect our privacy. Knowing which companies do is way harder than it should be. Our friends at <a href="">Ranking Digital Rights</a> just made this easier.</p> <p>Their first <a href="">Corporate Accountability Index</a> measures how well 16 internet and telecommunications companies perform on respecting user privacy, employing solid security practices, allowing encryption, and more.</p> <p>Their work distills mile-long TOS agreements, occasional transparency reports, and other public statements. The <a href="">ranking</a> show those companies that have good policies and follow through, and those that don’t.</p> <p>As a whole, the internet services that we rely on <a href="">have a long way to go</a>. Companies do not properly disclose how they <a href="">collect</a>, use, <a href="">store</a>, and <a href="">share user information</a>. Neither do they <a href="">communicate about third-party requests to remove or share user data</a>, as in the case of a court order or subpoena.</p> <p>By and large, citizens <a href="">cannot encrypt their own data while using services that internet companies provide</a>. <a href="">Nor do they have any say over how a company collects and shares their data</a>.</p> <p>The <a href="">what and why</a> of this report should be quite clear: we are leaving massive footprints on the internet and have little knowledge of how it’s used. Ranking Digital Rights has made the <a href="">full data available for download, including researchers’ comments and responses from the corporations where available</a>. We were pleased to partner with Ranking Digital Rights and <a href="">Beekeeper Group</a> to develop a set of web tools to communicate and explore the data.</p> <p>The Guardian have <a href="">put together some extensive coverage of the report</a>. It’s worth a read. Also worth a shout-out is the <a href="">Mapbox privacy statement</a>, which we think should be a model.</p> 2015-11-03T12:00:00+00:00 Development Seed Howdy Miles Watkins! <p class="dropcap"><a href="">Miles Watkins</a> is the newest member of our team!

For years we were primarily concerned with opening data any way possible. It has quickly become clear that it matters how we open data. We need to be open about the methods that produced the data, get the right type of open license, solve for reliability and sustainability, and consider the potential users and value of the data. And the software we use really matters.</p> <p>At Development Seed <a href="">we build open source tools for open data</a>. We built <a href="">Libra</a> and <a href="">landsat-util</a> to make it easier to work with open satellite imagery data. We are working to deploy the software behind <a href="">OpenStreetMap to allow the Philippines to collaborative manage road data</a> across the whole of government. <a href="">And many more.</a></p> <p>There are strong reasons to use open source tools in open government.</p> <ul> <li><strong>As resources for open data evolve, open software can more easily be adapted to new business models and deployment strategies.</strong> Open data companies have been critical in helping quickly scale open data practice and to solve the hard technical challenges involved in heavy and complex data. Open data companies creating open tools give government better ability to weather changes in the market, and give governments the flexibility to take on their own management of the system as their resources grow or shrink.</li> <li><strong>Open source tools offer citizens transparency into the open data pipeline.</strong> This allows citizens to check the math, to replicate results, and to identify technical issues that compromise the quality or availability of the data.</li> <li><strong>Open source allows us to better pool our resources for better tools.</strong> Governments on the cutting edge can help to subsidize the market. Better software will be available for governments with limited resources and the barriers will be lower for open source startups in developing democracies.</li> </ul> <p>Open source may not work for every need. But governments that are committed to tools for citizen empowerment, should strongly consider open tools when investing in software.</p> <p>If you are at OGP, we will have a great panel at 3:00 on the use of open source tools for open government. <a href="">Please join us</a>.</p> <figure class="align-center"> <img src="/assets/graphics/content/set/opentools_1final.svg" alt="The Open Data pipes aught to be open" /> </figure> 2015-10-28T00:00:00+00:00 Development Seed Open Geo at the OGP summit <p class="dropcap">Mexico City is the stage of the <a href="">Open Government Partnership summit</a>, bringing together 1500 open data advocates from civil society, businesses, and government officials from 70 countries. One big theme at this years conference will be open geodata.</p> <p>Managing geo data is one of the areas that traditionally has been overlooked, despite its importance for government. Mikel Maron has <a href="">a great post</a> on how open geodata is going to be vital to achieving global development goals. It’s great to see that open geo is a substantial part of this year’s agenda and that the open geo community has rallied around the event.

For this half of the worlds population, any economic shock can be crippling and even fatal. The microinsurance industry attempts to lessen these shocks by providing small, low-premium insurance policies to those in need. The availability of mobile phones has made it easier to enroll customers, accept payments, and deliver payouts. However a lack of data still presents a tremendous barrier to creating new insurance products. Better data can lower the barriers to providing low cost, sustainable insurance to the world’s poorest.</p> <p>The <a href="">Microinsurance Network</a> launched a <a href="">World Map of Microinsurance</a> to provide market data on microinsurance in over 120 countries. This data allows insurers to create more effective products and promotes transparency within the industry. Governments and development organizations can use this data to craft better policies and market opportunities.</p> <figure class="align-center"> <a href=""> <img src="/assets/graphics/content/prose/microinsurance-01.png" alt="World Map of Microinsurance" /> </a> <figcaption>World Map of Microinsurance</figcaption> </figure> <p>The <a href="">World Map of Microinsurance</a> allows users to explore microinsurance data collected by the <a href="">Microinsurance Centre</a> from Latin America, Africa, and Asia. Multiple filters and aggregations create many ways to explore the data. Small cards show more detailed data at the country level. And if you want access to the raw data, there’s always a link to the CSV.</p> <figure class="align-center"> <img src="/assets/graphics/content/prose/microinsurance-02.png" alt="World Map of Microinsurance" style="height:250px" /> <figcaption>Raw data provides additional opportunities for transparency and data distribution.</figcaption> </figure> <p>Gathering data for this industry will remain important as the industry continues to emerge.

The article does a great job of discussing the social and development implications of their approach. Frequently updated imagery and a solid distribution pipeline get imagery into the hands of decision makers. These are powerful tools for everything from precision agriculture to forestry management to monitoring for elections.</p> <p>The article fails to mention the powerful commitment both of these organizations have made to open knowledge. Aquila sells satellites and licenses their designs for commercial use, but they are also opening up all their hardware designs under GPL for public use. Astro Digital recognizes the value of open source imagery processing. When we built Astro Digital’s platform we highly leveraged <a href="">landsat-util</a>, <a href="">landsat-api</a> and <a href="">Libra</a>. Throughout, Astro Digital supported the development of Libra and encouraged us to contribute back to landsat-util. Further, Astro Digital has committed to host Landsat data on their platform for free for programs such as <a href="">OpenAerialMap</a>.</p> <p>Aquila Space and Astro Digital know that supporting open source helps them grow and thrive. We couldn’t agree more. We’re proud to work with them and with other satellite companies that open their data for research and humanitarian purposes.</p> <figure class="align-center"> <img src="/assets/graphics/content/prose/aquila-trip.jpg" alt="A trip to Aquila Space" /> <figcaption>A tour of the Aquila Space facilities, my aerospace professors would be so proud.</figcaption> </figure> 2015-09-29T00:00:00+00:00 Development Seed An OSM firehose <p class="dropcap">We just created <a href="">Planet Stream</a> a Twitter-like firehose of OSM data. Planet Stream combines the <a href="">Augmented Diffs</a> capabilities of the Overpass API with the contribution metadata from <a href="">osm-meta-util</a> in a fully-featured real-time data stream that developers can use to analyze OSM contributions in real-time.</p> <p>Planet Stream is a powerful tool for analyzing OSM feature data and contribution metadata side-by-side. You can use Planet Stream to coordinate tracing efforts around a natural disaster, to build an app showing the leading OSM contributors in your neighborhood, to quickly build a community of people editing hiking trails, or to provide automated feedback for common tagging mistakes.</p> <p>Mapping efforts such as <a href="">MissingMaps</a> and the <a href="">HOT tasking manager</a> use hashtags to track efforts. During the Nepal crisis, organizations used <a href="">osm-meta-util</a> in combination with <a href="">OSM History</a> to analyze volunteer contributions per hour. Planet Stream takes this even further by providing access to complete OSM data in real-time. <a href="">Dylan</a> and I built an <a href="">OSM Hashtag Leaderboard</a> that uses Planet Stream to show what hashtags are trending in contributions over the last six hours. Tools like the OSM Hashtag Leaderboard can help to build better mapathons and increase community engagement.</p> <figure class="bleed-full"> <iframe width="100%" height="600px" frameborder="0" src=""></iframe> <figcaption>Trending Tags on OSM -- <a href="">View full screen.</a></figcaption> </figure> 2015-09-28T10:00:00+00:00 Development Seed Hello Dylan Moriarty! <p class="dropcap"><a href="">Dylan Moriarty</a> has joined our growing team as a designer and cartographer.

This series of conferences convened the rich open data community in Latin America. I was there to talk about our open mapping and open contracting work and to learn about the incredible projects and teams across the region.</p> <p>Here is my favorite experience from each conference:</p> <h2 id="state-of-the-map-latam">State of the Map LatAm:</h2> <figure class="align-center"> <img src="" /> <figcaption>_Image Source: Flikr, Wille Marcel_</figcaption> </figure> <p>The first State of the Map in Latin America showed the depth of the community and its unique characteristics. Over 100 people attended. Compared to State of the Map US, there was much more attention on data imports, such as the <a href=",_IBGE,_Brasil_import#Import_Addressess_from_CNEFE">integration of Brazilian address and road names from the National Registry of Addresses for Statistical Means</a>. The individuals leading these initiatives wanted to ensure that the good data they collected would benefit the larger OSM community. Challenging the notions of what it means to contribute to OSM is an important topic that I hope the community will continue to address.</p> <h2 id="abrelatam">Abrelatam</h2> <figure class="align-center"> <img src="" /> <figcaption>Experiencing my first unconference. _Image Source: Twitter @cuidadnoi_</figcaption> </figure> <p>Abrelatam’s unconference structure provided an environment to brainstorm, and hear from a wider slice of the open data community. Discussions tended to focus on the open data policies and approaches rather than technical implematation. One of the common themes amongst the projects presented was transparency of political messages in the media, shown in projects such as <a href="">Cheaquado</a>, <a href="">Mapa de Medios</a>, and <a href="">Yo Quiero Saber</a>.</p> <h2 id="con-datos">Con Datos</h2> <figure class="align-center"> <img src="" /> <figcaption>_Image Source: Twitter @palamago_</figcaption> </figure> <p>At Con Datos, I most closely followed the conversations on the Open Contracting Data Standard (OCDS) data. The OCDS is common approach to publishing data on government contracts that makes it much easier to examine contracting within and between countries. Development Seed has been working on a few projects that involve OCDS, including a project with the Government of Mexico that will launch at <a href="">OGP</a>. There were multiple sessions at Con Datos revolving around OCDS, the high point being the project showcase during the last conference session. The <a href="">visualizations</a> presented by the National Management of Public Contracting in Paraguay are particularly awesome as they highlight different steps of the contracting process.</p> <p>My Santiago trip was my first as a Development Seed team member and I couldn’t have asked for a better welcome from the open data community. I’m looking forward to continuing these discussions in the weeks to come.</p> 2015-09-24T00:00:00+00:00 Development Seed Illustrating Development Seed <p class="dropcap">Creating illustrations based on complex concepts such as remote sensing, open data or the internet is a fun and challenging aspect of my work at Development Seed. Behind these illustrations is a process that involves contemplation and visualization before coming to a final design that successfully communicates the intended message.</p> <figure class="align-center"> <img src="/assets/graphics/content/prose/mindmap_scan2.png" alt="Mind Map Sketch" /> <figcaption>A Mind Map gets ideas out fast</figcaption> </figure> <h2 id="finding-meaning-through-process">Finding meaning through process</h2> <p>The first step in structuring this thought process is to create a Mind Map, which is a great tool to capture one’s thoughts and bring them into the visual realm. In this case, the resulting illustration will accompany an article that focuses on the open data movement and its collaborative relationship between government and citizens. So I pulled a couple evocative key words (data and government) to use as a central focus to branch off more ideas.</p> <p>The thinking in this initial stage is meant to be naive and playful, and without fear of making mistakes along the way. Being willing to run with ideas and having them fail is a crucial part of this thinking process because it allows us to be foolish, experimental, and mentally available for anything that might be influential. This is best described as <a href="">serious play</a>, a methodology developed by Graphic Designer Paula Scher who warns designers about being solemn in their design thinking.</p> <blockquote> <p>“Find out what the next thing is that you can push, that you can invent, that you can be ignorant about, that you can fail with, because in the end that’s how you grow and that’s all that matters.” - Paula Scher</p> </blockquote> <p>The next step is creating small thumbnail sketches to find general shapes that achieve an appealing form. Making many rough sketches means more options to compare and eventually determine which ones are most successful in terms of composition.</p> <p>In these thumbnails I isolated two ideas from the Mind Map: the government buildings and internet as tubes ideas. I wanted these to be central elements of the illustration since they are very representative of the core aspects that this article describes, as well as providing great visual inspiration to draw from.</p> <p>A select few are then sketched out and digitized in a larger format to allow for more detail to be introduced.</p> <figure class="align-center"> <img src="/assets/graphics/content/prose/thumbnails2.png" alt="Final versions" /> <figcaption>Thumbnail sketches allow me to quickly explore different concepts</figcaption> </figure> <p>Based on the initial explorations, I usually make a couple iterations of the chosen concepts. Then, incorporating some substantial play, I embellish, simplify, or even rule out the rough versions. I often refer back to the mind map to keep the ideation process fruitful, flowing, and most importantly fun.</p> <p>Once the version that is most successful in communicating the message is selected, it begins to be crafted and pushed further towards a final image. Sometimes this requires changing large aspects to accurately demonstrate the meaning of the content, and sometimes it only requires minor tweaks to get to a finalized point.</p> <p>Each illustration has a <em>voice</em> that coincides with its surroundings. Limiting the aesthetic details of the image that define that <em>voice</em>, gives the image another level of quality and establishes an illustrative style.</p> <figure class="align-center"> <img src="/assets/graphics/content/prose/opentools_process.svg" alt="Final versions" /> <figcaption>Different takes on the same concept</figcaption> </figure> <h2 id="a-signature-style">A signature style</h2> <p>A distinguished illustrative style that reinforces the content of our website was thoroughly deliberated with the team. This particular style includes a monochromatic color scheme to better suit the duo-tone color palette of the site, which ended up being a fiery orange pulled from our branding. It also follows the minimalist style with a focus on linear motifs which can be dynamic while still complementing the text, as opposed to completely absorbing the reader in the image.</p> <p>Developing concepts within an aesthetic guideline creates visual consistency and reinforces the brand identity and visual style. Concurrently, setting design limitations actually promotes ideation and works much like a compass to focus creative thinking in a specific direction. These processes may not be for everyone, yet all design requires some form of methodology and play that speaks to one’s own vision and makes the end product unique and well formed.</p> <blockquote> <p>“Play prepares us for the unexpected” - Marc Bekoff, Contemporary Biologist</p> </blockquote> <p>The final illustration now lives harmoniously in the <a href="">Open Tools for Open Data</a> article.</p> <figure class="align-center"> <img src="/assets/graphics/content/prose/dslogo_upgrade3-01.png" alt="DS logo" /> </figure> 2015-09-18T00:00:00+00:00 Development Seed Join the #SatSummit on November 9th <p class="dropcap">On November 9th in Washington, DC we’re bringing together satellite industry leaders and innovative global development institutions for #SatSummit, a one day event, where we’ll start a conversation about how best to work together.

As a cartographer, time and again I elected to use software with a visual interface - from QGIS to Mapbox Studio. But I kept running up against situations when I would look up how to do something and the advice told me to turn to a tool that was only available on the command line. And I kept running.</p> <p>But, as Zed Shaw eloquently states in his <a href="">command line crash course</a>:</p> <blockquote> <p>If you have an irrational fear of the command line, the only way to conquer an irrational fear is to just shut up and fight through it.</p> </blockquote> <p>This post is for people like me, who generally understand mapping and GIS, but don’t know much of anything about the command line. I’ll talk about why you should care about it, cover some of the basics, and go through a quick example of how to use two powerful command line tools for manipulating geodata - ogr2ogr and GDAL. I’ll leave you with other command line resources for further exploration.</p> <h3 id="what-is-the-command-line-and-why-should-you-care">What is the command line and why should you care?</h3> <p>The command line (also known as command line interface, or CLI) gives you access to your computer’s innards. It’s how you talk to your computer directly, without going through the intermediary of a graphical interface. You type things in, and the computer responds by typing things out on the screen. A <em>shell</em> is the interface where this typed interaction between human and computer takes place. On Mac and Linux, the default shell is called bash, which you access through the Terminal application. On Windows, it’s PowerShell.</p> <p>Attempting to turn your computer from a magical black box into something that you have more control over can be intimidating. But by learning the command line, you have access to geo tools that are only accessible there, or you can do your work much faster than through a heavy software program. At first, it might feel like you are blindly following instructions, but with more practice you’ll start to feel like you understand more of what you are doing.</p> <blockquote> <p>Why? Because if you want to learn to code, then you must learn this. Programming languages are advanced ways to control your computer with language. The command line is the baby little brother of programming languages. Learning the command line teaches you to control the computer using language. Once you get past that, you can then move on to writing code and feeling like you actually own the hunk of metal you just bought.</p> <footer>Zed Shaw, <cite title="The Command Line Crash Course"><a href="" title="Visit The Command Line Crash Course">The Command Line Crash Course</a></cite></footer> </blockquote> <h3 id="getting-started">Getting started</h3> <p>First, you’ll need to <a href="">install GDAL</a> so that down the road we can do some geoprocessing with it. GDAL and ogr2ogr are two amazing command line utilities - GDAL can be used for processing raster data, while ogr2ogr is for operations with vector data types (<a href="">read more</a> about vector vs. raster data types).</p> <p>Now let’s get started on the command line. You’ll need to open up your shell. On Mac, press <code>⌘ + spacebar</code> to open your computer search, type in <code>Terminal</code> and press <code>return</code>. On Windows, open up PowerShell. (I am working on a Mac, so that is where all of my screenshots and examples come from.)</p> <p>Once it’s open, you will see something that looks more or less like this, but with the name of your username instead of mine, followed by <code>$</code>. On Windows, you will see something similar but followed by <code>&gt;</code>.</p> <figure class="align-center"> <img src="/assets/graphics/content/prose/geo-command-line-01-terminal.png" alt="The Mac Terminal" /> </figure> <p>We will use the shell to access different files and programs on your computer. So, first we need to find which directory (aka folder) we are in. Type <code>pwd</code> into your shell. This means <code>present working directory</code> and tells you the location that the shell is currently accessing.</p> <figure class="align-center"> <img src="/assets/graphics/content/prose/geo-command-line-02-pwd.png" alt="pwd on the command line" /> </figure> <p>The shell prints out <code>/Users/robin</code>, telling me that that’s the directory I’m currently in.</p> <p>Now, I want to see everything that’s in the <code>/Users/robin</code> directory, so I type<br /> <code>ls</code> and get this on the screen:</p> <figure class="align-center"> <img src="/assets/graphics/content/prose/geo-command-line-03-ls.png" alt="ls on the command line" /> </figure> <p>Now we see the Desktop in there. To get to any directory or file within the present working directory, you just type in <code>cd</code> and then the name of the directory or file. <code>cd</code> stands for <code>change directory</code> and this allows you to move around to a different directory on your computer.</p> <p>So for me, I just type in <code>cd Desktop</code> (Side note: you can use the <code>tab</code> button as a shortcut - so if I type the first couple of letters of <code>Desktop</code> and then hit tab, it will autofill with the full directory name so I don’t have to type it out completely). Now when I type in <code>pwd</code>, the shell prints out <code>Users/robin/Desktop</code>, showing me that I’m inside my Desktop directory:</p> <figure class="align-center"> <img src="/assets/graphics/content/prose/geo-command-line-04-cd.png" alt="cd on the command line" /> </figure> <p>When navigating around your directories, <code>..</code> means <code>parent directory</code>. Now that I am in the Desktop, if I want to go back to <code>Users/robin/</code> I just type in <code>cd ..</code> and it takes me up to the “parent” of my current directory, meaning the directory that my current directory is within.</p> <h3 id="actually-doing-something-geospatial-using-gdal-and-ogr2ogr">Actually doing something geospatial using GDAL and ogr2ogr</h3> <p>We’re going to convert a polygon shapefile to a GeoJSON format and then clip a satellite photo to the bounds of that polygon, all using GDAL and ogr2ogr, which you downloaded earlier. You can download the <a href="">zipped shapefile</a> and the Landsat <a href="">satellite image</a>. We’re looking at Dane County, Wisconsin (because Wisconsin in the summertime is lovely).</p> <p>Go ahead and download those files, <code>wisconsin.tif</code> and <code></code>. They’ll probably be in your Downloads folder. In my case, I’ve placed them on my Desktop. Unzip the zipped shapefile, <code></code>. It will create its own folder within whatever directory the zipped file is in, so keep that in mind when you are doing the following commands.</p> <p>First, we’re going to convert the shapefile into a GeoJSON. You’ll need to navigate to the folder where your shapefile is saved using the <code>cd</code> command to change directory and <code>pwd</code> to check and make sure you’re in the right place. You can always use <code>ls</code> to list the files in that directory and make sure they’re in there. Then you’ll type in this command:</p> <p><code>ogr2ogr -f "GeoJSON" dane-county.json dane-county.shp</code></p> <p>Let’s break that down. <code>ogr2ogr</code> is the command you’re using, which you have access to because you installed GDAL above. As is the case with many command-line utilities, after the command you have some optional flags. These are extra conditions or parameters that you can set to tell the program how to do what you want it to do. In this case, we are using the <code>-f</code> flag, which tells the command that we want to specify a filetype that we want the output to be saved as. After the <code>-f</code> flag, we specify the filetype, in this case, GeoJSON. Then we put in a name for the output (I put <code>dane-county.json</code> but you can put <code>output.json</code> or <code>awesomeness.json</code> or whatever you want). Finally, we put the input file, <code>dane-county.shp</code>.</p> <p>You should see in your directory that you have a file called <code>dane-county.json</code> and you have converted your shapefile to a format better suited for the web!</p> <p>Now we’re going to practice using GDAL to clip a Landsat satellite image to the bounds of a shapefile. First let’s open up that beautiful TIF file to see what it looks like (you already know how to simply double-click on the file to open it, but that’s cheating! Use the command line!). The command we’re going to use is <code>open</code>, which opens the file using the default program. Using the commands <code>cd</code> to change directories and <code>pwd</code> to check which directory you’re currently in, navigate to the directory where your files are located. Then type in <code>open</code> and the name of your file (in this case, wisconsin.tif). For Windows users, navigate to your directory and then <a href="">just type in the file name</a>.</p> <figure class="align-center"> <img src="/assets/graphics/content/prose/geo-command-line-05-open.gif" alt="open file" /> </figure> <p><code>open Users/robin/Desktop/wisconsin.tif</code></p> <p>(Pro-tip: You can also drag-and-drop the file from the directory onto the command line to get the full path name.)</p> <figure class="align-center"> <img src="/assets/graphics/content/prose/geo-command-line-06-drag-n-drop.gif" alt="drag and drop file" /> </figure> <p>Now we know what the image looks like. The GeoJSON that you just converted is a polygon of Dane County, Wisconsin, which takes up part of the area of the satellite image (you can always open it up in the GIS program of your choice to take a look). To crop the image to the GeoJSON, we’re going to use this command (I recommend typing the command in yourself, don’t copy/paste it):</p> <p><code>gdalwarp -cutline dane-county.json -crop_to_cutline wisconsin.tif dane-county.tif</code></p> <figure class="align-center"> <img src="/assets/graphics/content/prose/geo-command-line-07-crop-to-cutline.gif" alt="gdalwarp crop to cutline" /> </figure> <p>Let’s break this down to make sure we understand what’s going on.</p> <p><code>gdalwarp</code> is a powerful <a href="">GDAL command</a> that allows you to reproject, crop, and warp georeferenced raster files. The documentation on <code>-cutline</code> says:</p> <figure class="align-center"> <img src="/assets/graphics/content/prose/geo-command-line-08-cutline.png" alt="gdal cutline" /> </figure> <p>That doesn’t really make much sense. That’s why I rely on other people for help because the formal documentation is often unclear. I got the above command from Derek Watkins’ <a href="">GDAL cheat sheet</a>.</p> <p>I know from looking at the command that <code>-cutline</code> is followed by the vector file, so my guess is that <code>-cutline</code> is indicating the bounding area that you want to crop the raster to. Then comes <code>-crop_to_cutline</code>, followed by the original TIF file and then the name that we want to give to the output TIF file. The output will save in your present working directory unless you specify a path to a different directory.</p> <p>We know how to open a file now, so let’s open up the output and see what it looks like.</p> <figure class="align-center"> <img src="/assets/graphics/content/prose/geo-command-line-09-open-dane-county.gif" alt="open output file" /> </figure> <h3 id="go-forth-and-command">Go forth and command</h3> <p>You won’t learn the command line overnight, and this post isn’t going to get you all the way there, but it’s a start.

I downloaded the Landsat image used here using <a href="">landsat-util</a>, a command-line utility that lets you search for, download, and process Landsat imagery.</p> <p>Part of what’s intimidating about the command line is that many of the online resources out there are unclear or aimed at people who already have a deeper understanding of it.

Collecticons includes <a href="">a processing script</a> to generate an icon font for use with your CSS or SASS.</p> <h2 id="icons-matter">Icons matter</h2> <p>We use a lot of iconography. Clean icons convey meaning simply and quickly. Clean icons help us to build an <a href="">intuitive interface to search satellite imagery</a> and to tell a clear story that <a href="">some oil is dirtier than others</a>.</p> <p>There are several ways to include icons in a project. We find the icon font approach most suitable to our process, simply because icon fonts are great:</p> <ul> <li>They are ridiculously lightweight;</li> <li>Only one single font file is needed instead of multiple images, requiring just one HTTP request;</li> <li>The icons can be scaled to any size, and easily styled using CSS;</li> <li>By using <a href="">PUA code points</a> for the glyphs, you prevent screen readers from reading these characters and thus addressing accessibility issues.</li> </ul> <h2 id="a-better-way-to-manage-icons">A better way to manage icons</h2> <p>We built <a href="">Collecticons</a> to improve our own development process. Previously we used <a href="">IcoMoon</a> to create a webfont but any small change to an icon required that we manually generate the font all over again. Over a project with many careful iterations to the icon set, this time adds up. So we built our own tools for icon management hat we could plug right into our development process.</p> <p>The <a href="">Collecticons Library</a> allows us to easily manage and reuse icons. Some of the icons were built on top of libraries. Most we made in house. With the <a href="">Collecticons Processor</a>, we generate the font and sass files automatically when we do our site build.</p> <p>Collecticons saves us time, makes our development process more efficient, and lets us borrow from tested icon conventions. We hope it does the same for you.

A mapathon, also known as a mapping party, is when a bunch of people get together to edit <a href="">OpenStreetMap</a>, the editable map of the world. Here’s a guide for organizing a mapathon, based on my experience organizing mapathons in Bogota, Colombia, and Madison, Wisconsin, along with great advice from people who have organized OpenStreetMap mapathons all over the world (thank you, you lovely people!).</p> <p>First things first: there is no one right way to run a mapathon. I will outline things to consider, but you don’t need to do all of these. Do what works for you, and <a href="">lean on the wonderful OSM community</a> for support when you have questions.</p> <h2 id="preparation">Preparation</h2> <h4 id="find-a-co-organizer-or-two">Find a co-organizer (or two)</h4> <p>A lot can go into organizing a mapathon, including the preparation beforehand and the actual event. It’s helpful to have someone to split up the duties with and who can help attendees on the day of the event.</p> <h4 id="determine-your-priority">Determine your priority</h4> <p>Are you organizing a mapathon to add a lot of data to the map, or are you trying to introduce new people to this awesome project? These things aren’t mutually exclusive, but it’s a good idea to keep your main goal in mind as you are planning and running the mapathon.</p> <h4 id="find-a-location">Find a location</h4> <p>Common places to hold mapathons include local schools, universities, businesses, libraries, restaurants, cafes, or parks. You’ll want to <a href="">check on the internet connection</a> at the location to try to avoid connectivity issues. Some mapathons have had issues when lots of people try to upload or download data from OpenStreetMap, so you can also check if different computers can connect through different IP addresses.</p> <p>You might be able to find a local business or organization to sponsor the event to provide food, drinks, and supplies.</p> <h4 id="decide-on-the-format">Decide on the format</h4> <p>Do you want to do surveying of a local area? Or will you be doing “armchair mapping,” contributing data to the map using aerial imagery or other existing data? If you are going to do outdoors surveying, I recommend meeting at a central indoors location to introduce everyone to OpenStreetMap, splitting up into groups to go off and map nearby, then coming back together at the end to add the collected data to the map. Think ahead of time of possible routes that people can take or certain things that people can map, like addresses, mailboxes, or restaurants. During the event, people are free to map whatever they want, but it’s good to have some ideas ready.</p> <h4 id="pick-your-tools">Pick your tools</h4> <p>There are tons of great tools out there to help you contribute to OpenStreetMap. You might want to stick with just one or two to teach at the mapathon so people don’t get overwhelmed by too many options. Or you can provide information about all of them and let people decide what works for them.</p> <ul> <li>For local mapping: <ul> <li><a href="">Field Papers</a></li> <li>Phone apps (OSMTracker, OsmPad, GoMap!!, Pushpin, to name a few)</li> <li><a href="">Mapillary</a></li> <li>Cell phone / camera</li> <li>A notepad</li> </ul> </li> <li>Remote mapping: <ul> <li><a href="">HOT Tasking Manager</a></li> </ul> </li> <li>Either: <ul> <li><a href="">Battle Grid</a></li> <li><a href="">MapRoulette</a></li> </ul> </li> </ul> <h4 id="pick-an-editor">Pick an editor</h4> <p>JOSM and iD are the main OpenStreetMap editors, with <a href="">JOSM</a> being the primary desktop application and <a href="">iD</a> as the main web-based editor. If you are expecting a bunch of new mappers, you should focus on iD, which has a simpler interface and doesn’t require a download. If you are an expert JOSM user, make sure to familiarize yourself with iD ahead of time so that you can help answer questions that come up. If you are planning to teach JOSM, make sure it is downloaded on available computers or advise people to download it on their own laptops ahead of time.</p> <hr /> <h2 id="outreach">Outreach</h2> <h4 id="collaborate">Collaborate</h4> <p>Reach out to other local organizations to see if they want to work together and help with outreach. This can include a local <a href="">OSM Meetup group</a>, <a href="">Maptime chapter</a>, school or university, or the general open-source community. Leverage other organizations’ email lists and social media presence. You can also organize a mapathon in coordination with a <a href="">nationwide U.S. mapathon</a> to get extra coverage.</p> <h4 id="get-out-the-word">Get out the word</h4> <p>Twitter is great, but there are a bunch of other ways to get out the word, too. You can put up flyers around the neighborhood, send out messages to local neighborhood or city lists, or post on <a href="">Nextdoor</a>.</p> <h4 id="asking-for-rsvps">Asking for RSVPs</h4> <p>It’s a good idea to ask people to RSVP for the event on Meetup, Eventbrite, or Facebook. People can still show up at the door, but it will help with planning if you have an idea whether you’ll have 5 or 55 people.</p> <hr /> <h2 id="the-day-of">The day of</h2> <h4 id="intro-to-osm-and-the-tools">Intro to OSM and the tools</h4> <p>Give a brief introduction to OSM. Some people prefer to do this as a 10-30 minute presentation at the beginning of the event, while others prefer giving 3-5 minute presentations throughout the event on different facets of OSM. You can talk about what OpenStreetMap is, different ways to contribute to the project, give examples of ways that it is used, and why open data is important.</p> <p>Be sure to introduce the tool(s) that you’re going to use during the mapathon. You can mention additional tools that people can use, but focus on just one or two.</p> <h4 id="welcome-newbies">Welcome newbies</h4> <p>Hopefully you’ll have people at your event who have never even heard of OpenStreetMap. That’s great! If a new mapper has a positive experience at a mapathon, that will make them more likely to support it in some way. There are lots of ways to do this:</p> <ul> <li>Emphasize that you and other experienced mappers are available to help with any questions.</li> <li>Match up experienced mappers with new mappers so that they have a dedicated person who they can go to with questions.</li> <li>Print “Get Started” guides with basic information about OSM and how to edit.</li> <li>Make sure people know that they don’t need to stay for the whole event.</li> <li>Point to additional resources that people can turn to after the event is over.</li> </ul> <h4 id="get-mapping">Get mapping</h4> <p>Go out and survey or start making edits. If you are doing outdoors mapping, make sure someone stays behind at the meeting location in case people show up late or one of the participants has mobility issues.</p> <h4 id="most-importantly-have-fun">Most importantly: have fun</h4> <p>Be enthusiastic and have a great time. You are the best ambassador for OpenStreetMap and getting people excited about contributing in whatever way they can.</p> <p>If you were able to get a sponsor, you can do something social after you’re done with the serious stuff.</p> <h3 id="resources">Resources</h3> <p>If you need more help, here are a few additional resources:</p> <ul> <li><a href="">LearnOSM</a></li> <li><a href="">TeachOSM</a></li> <li><a href="">Mapgive</a></li> <li><a href="">Humanitarian OpenStreetMapTeam</a></li> <li><a href="">Maptime</a></li> </ul> <p><em>Card photo by <a href="">Harry Wood</a></em></p> 2015-06-07T16:30:00+00:00 Development Seed OpenAerialMap Interface Design <p class="dropcap">We recently built several highly <a href="">usable</a> <a href="">imagery</a> <a href="">browsers</a>. Each allow users to get right to the data they want by browsing a map. This interface works well with Landsat imagery, which has a consistent coverage area. For large, complex imagery datasets like <a href="">OpenAerialMap</a> we created a new type of grid interaction.</p> <h2 id="designing-for-complex-map-data">Designing for complex map data</h2> <p>Last week we launched the <a href="">beta version of OpenAerialMap</a> a tool for finding open satellite and drone imagery. We knew that even in beta, <a href="">usability is going to be critical</a> to the adoption and success of OpenAerialMap.</p> <p>OpenAerialMap is a site that has to show a lot of data. It features imagery from different providers, with different aspect ratios, and captured on different dates. Presenting such data in a meaningful and usable way was challenging, especially considering that individual areas can contain multiple imagery.</p> <h2 id="enter-the-grid">Enter the grid</h2> <figure class="align-center"> <img src="/assets/graphics/content/prose/battleship-board-game.jpg" width="3456" height="2304" alt="The grid in action" /> <figcaption>Battleship board game. <small>Image by <a href="" title="View original image">John Morgan</a></small>.</figcaption> </figure> <p>Drawing inspiration from <a href="">hexgrid experiments using Turf</a> and good old <a href="">battleship game</a>, we created the grid for showing the density of imagery at any area. The grid breaks the world up into units that are easy to interact with.</p> <p>We used an “always square” grid disregarding the map projection. The result is a beautiful, clean, easy-to-use grid where all interactions with the map are consistent and as visual appealing as possible.</p> <p>We color grade each grid cell according to the number of images intersecting them. This way we avoid bloating the map with useless information and provide a sense of density. The grid works as a visual guide where at a quick glance the user can easily grasp where and how much imagery is available.</p> <figure class="bleed-full"> <img src="/assets/graphics/content/prose/oam-browser-interaction.gif" width="2545" height="764" alt="The grid in action" /> <figcaption>The grid in action.</figcaption> </figure> <p>Selecting a cell reveals a panel with a list of imagery. From there, the imagery can be previewed on top of the map, downloaded or, when available, used as the baselayer of another map.</p> <p>Designing usable map interactions requires real thoughtfulness. But it makes all the difference between a tool that <a href="">people love</a> and one that is forgotten.</p> 2015-06-05T10:00:00+00:00 Development Seed Off to State of the Map <p class="dropcap">We will be at <a href="">State of the Map US</a> this weekend at the United Nations.

While the vast majority of deaths are in low and middle income countries, air quality continues to worsen in cities across the world.</p> <p>So we made an open data pipeline and API for citizens to better understand the quality of the air they breathe.</p> <figure class="align-center"> <a href=""><img src="" /></a> <figcaption>Pollution seen in Ulaanbaatar, Mongolia.</figcaption> </figure> <p>Using accurate, low-cost sensors, people can measure the concentration of harmful particulate matter in their homes or places of work. Feeding into our data pipeline, these sensors create a central repository of data about air quality that anyone can access through the API. With several sensors scattered across an area, citizens create meaningful data that they can use to advocate for better policy, zoning laws, and regulation.</p> <p>We’ve been working with a group of hardware engineers, infrastructure builders, and journalists to develop an air quality monitoring system powered by an open API and low-cost sensors – some great folks at <a href="">InfoAmazonia</a>, <a href="">Feedback Labs</a>, <a href="">FrontlineSMS</a>, <a href="">Groundtruth Initiative</a>, <a href="">EJN</a> and <a href="">Internews</a>.</p> <p>Earth Journalism Network (EJN) and InfoAmazonia designed, manufactured, and deployed <a href="">Dustduinos</a>, Arduino-based sensors that detect particulate matter at 2.5µm and 10µm. The Dustduino uses an open spec that was <a href="">optimized for low power consumption and SMS communication and wifi</a>. To ensure connectivity in areas without wifi, <a href="">FrontlineSMS</a>, adapted their SMS services to support the Dustduino.</p> <p>Our role was to turn the raw input data into actionable information. We built a data pipeline to make this data publicly available through a <a href="">flexible API</a> as well as for download. The API allows anyone to build apps on top this information, or integrate it with other tools. Downloads will allow researchers and advocacy organizations to work with the data in tabular format.</p> <p>Open and available air quality data can empower citizens in vulnerable areas to have more say in the policies that affect their local air quality as well as providing researchers with valuable insight into potentially understudied areas. This kind of change happens from the ground up. We will continue to support this change by building open-source data pipelines, better sensors, and a robust community for open air quality data.</p> 2015-06-03T10:00:00+00:00 Development Seed Welcome Robin Tolochko! <p><img src="" alt="Robin with bike" /></p> <p><a href="">Robin Tolochko</a> loves maps.

OpenAerialMap makes it easy to share and find open satellite and drone imagery. This is critical to the work of the disaster response community. We are launching this tool in close partnership with the <a href="">Humanitarian OpenStreetMap Team (HOT)</a>.</p> <figure class="align-center"> <img src="" /> </figure> <p>OpenAerialMap is a set of tools for searching, sharing, and using open satellite and drone imagery. This initial release includes the core infrastructure to catalog petabytes of open imagery. It also includes an extremely usable API and an elegant web interface to submit, search and download available imagery.</p> <figure class="align-center"> <img src="" /> <figcaption>Search for available imagery.</figcaption> </figure> <figure class="align-center"> <img src="" /> <figcaption>Select scenes by grid.</figcaption> </figure> <figure class="align-center"> <img src="" /> <figcaption>Preview imagery and get metadata information.</figcaption> </figure> <h3 id="rebooting-a-great-concept">Rebooting a great concept</h3> <p>The OpenAerialMap concept has bounced between several attempts over half a decade. Previous attempts failed to take off. HOT <a href="">reinitiated the concept</a> this year with funding from the <a href="">Humanitarian Innovation Fund</a>. We worked with the HOT and others in the open imagery community to reimagine an approach to OpenAerialMap that we expect to be much more successful.</p> <ul> <li>We focused on simple, usable toolset that meets the clear needs of the humanitarian response community. The underlying architecture is flexible enough to be immediately useful to research, resource management, urban planning, and other communities. However, we decided to first build a frictionless interface for the clear needs of the disaster response community.</li> <li>We are extremely focused on community. From day one, we involved other organizations and developers like <a href="">Azevea</a>, <a href="">Planet Labs</a>, <a href="">Cadasta</a>, <a href="">OpenDroneMap</a> and HOT’s own developers.</li> <li>With these and other groups, we reimagined OpenAerialMap along a network model. Rather than try to house all the open imagery out there, OpenAerialMap is a node and index for a larger network or open imagery - the <a href="">Open Imagery Network</a>.</li> </ul> <h3 id="a-network-approach-to-open-imagery">A network approach to open imagery</h3> <p><a href="">Open Imagery Network (OIN)</a> is a simple framework and license for placing imagery into an open source license. Participants in the OIN adopt a common metadata scheme to describe the imagery they are making available, and standardized ways to broadcast and access that data. This allows us to build tools that search across all open imagery data without requiring one entity to host all of it. We’re working with HOT, Planet Labs, Cadasta, Azavea, OpenDroneMap, and others to develop OIN and to build OpenAerialMap as the first node in that network.</p> <h3 id="your-feedback">Your feedback</h3> <p>A vibrant community will be critical to the success of OpenAerialMap. Check out the beta version and send us feedback on <a href="">Twitter</a>. Or open an issue or make a contribution <a href="">on Github</a>. Currently OpenAerialMap has imagery from the Nepal earthquake response, high resolution satellite imagery of Finland, <a href=";subject=prog&amp;topic=nai">agriculture imagery</a> over Nebraska, and drone imagery from Vanuatu. We’ll work to add functionality and features toward an initial release candidate later this summer.</p> 2015-05-27T12:00:00+00:00 Development Seed Open Geospatial Happy Hour <p class="dropcap">The <a href="">Geospatial World Forum</a> is well under way in Lisbon and we’re impressed with the diversity of people and talks at the event.</p> <p>On Thursday night, we are organizing an Open Geospatial Happy Hour at Café Fábulas with our friends from <a href="">Planet Labs</a>. This Happy Hour is a great opportunity to meet people and talk about open data, mapping and satellites in a more informal setting.</p> <p>You don’t have to be attending the conference to join the happy hour, just let us know if you’re coming. You can <a href="">RSVP here</a>.</p> <p>If you are participating in the GFW, make sure to check out our <a href="">workshop and talk</a> in the exhibition hall on Thursday morning.</p> 2015-05-27T00:00:00+00:00 Development Seed Oil-Climate Index Launches <p class="dropcap">Nearly 100 million barrels of oil flow through the global oil supply chain every day. But not all oils are created equal. When you consider the full oil processing lifecycle, some types of oil are responsible for nearly twice as much greenhouse gas as others. This is important information for oil procurement and energy policy. Smarter oil selection can lead to significant reduction in greenhouse gases without even touching overall oil consumption. We worked with the Carnegie Endowment to launch the <a href="">Oil Climate Index website</a> to help consumers and policymakers make smarter decisions on oil.</p> <h3 id="extracting-oil-data">Extracting Oil Data</h3> <p>Oil emission data has traditionally been extremely hard to find. The source data for most oil fields is often secret and some of the models needed to calculate total greenhouse gas emissions have been proprietary. The Carnegie Endowment made a major contribution to understanding the climate impacts of fossil fuels with the <a href="">Oil-Climate Index</a>. The Oil Climate Index is the first study using entirely open-source models for evaluating greenhouse gas emission. These models were developed in a collaboration by Carnegie Endowment’s Energy and Climate Program, Stanford University, and the University of Calgary. In addition, the Oil Climate Index also collected model input data for 30 popular and emerging oils.</p> <figure class="align-center"> <img src="" alt="Scatter plot" width="759" height="587" /> <figcaption>Explore relationships between oil properties</figcaption> </figure> <p>The data is extremely complex and nuanced. Depending on what you want you want to do with an oil, making diesel vs jet fuel, different oils may be better. An improvement in an extraction or refinement process may have a significant climate benefit for one oil but not for another. To make this data useful to scientists, investors, policy makers, and interested citizens we built a <a href="">flexible data exploration tool</a>. The tool makes reasonable assumptions to allow immediate comparison, but also allows users to explore how specific factors change the overall climate impact of each oil. Most importantly, all of the data and the modeling methodologies are open and available for download.</p> <h3 id="designing-for-complexity">Designing for complexity</h3> <p>We limited graphing options to the most meaningful properties to provide flexibility without unnecessary complexity. To visualize the Oil-Climate Index, we weren’t just showing static data, we were visualizing results of complex models. Processing all the data in the browser is impractical. Instead, we picked several model input parameters that are most meaningful and calculated their data up front. We built processing tools behind the site to recalculate this data as Carnegie extracts data on new oils.</p> <figure class="align-center"> <img src="" alt="Model parameters" width="370" height="172" /> <figcaption>Model parameters allow the user to customize the model and data output</figcaption> </figure> <p>For more information on the Oil-Climate Index hit us <a href="">on Twitter</a>, ask <a href="">@DxGordon</a>, or check out these resources:</p> <ul> <li><a href=""></a></li> <li><a href=""></a></li> <li><a href=""></a></li> </ul> 2015-05-26T18:00:00+00:00 Development Seed We're sending a delegation to State of the Map US <p class="dropcap"><a href="">State of the Map US</a> is around the corner. We’re sending a robust delegation to the United Nations for the biggest OpenStreetMap conference ever.</p> <p>This is a critical meeting for OSM and for open data. OpenStreetMap is becoming too big to fail. It is now critical infrastructure for everything from urban planning to disaster response. We’ll join 1000 open mappers from dozens of countries at a truly international venue to discuss new opportunities and responsibilities for OSM.</p> <p>We’ll be talking about:</p> <ul> <li><strong>OSM-as-a-platform</strong> - What if governments could roll OSM internally as an open source stack to manage road data between agencies? Will wider use of software behind OSM lead to better OSM data? Better OSM software? Check out <a href="">Olaf’s talk</a> on our experience <a href="">rolling out OSM-as-a-platform in the Philippines</a>. Or talk to <a href="">Olaf</a>, <a href="">Derek</a>, or <a href="">Anand</a>.</li> <li><strong>Organizing mapathons</strong> - <a href="">Robin</a> will deliver a <a href="">lightning talk on organizing mapathons</a>. Hit her up to talk about making mapathon magic.</li> <li><strong><a href="">OpenAerialMap</a></strong> - OpenAerialMap will be an open catalog of satellite and aerial imagery. Find <a href="">Nate</a>, <a href="">Alireza</a>, and <a href="">Marc</a> to talk about our contributions to OAM.</li> <li><strong>OSM Meta Data</strong> - Want to understand the OSM community?

We will be talking with NGOs, government agencies, and researchers about how they can use open geospatial data and open source software. Our Lisbon team will host an open geospatial happy hour on Thursday.</p> <p>Open geospatial data is some of the most valuable data that government produce, generating billions of dollars in economic value and tremendous social good. Open geospatial data underlies everything from critical climate change research to many of the apps in your favorite app store.</p> <p><a href="">Libra</a> and <a href="">Landsat-util</a> are powerful open source tools for processing and analyzing Landsat data. On Thursday at 11:00 I’ll talk at the <a href="">Open Data track</a> about using these tools in combination with other open software like <a href="">QGIS</a> to work with open satellite data. At 9:00 Thursday <a href="">Alireza</a> and <a href="">Nate</a> will offer a hands on training on open tools for satellite data at the <a href="">the Open Source Imagery Tools workshop</a>.</p> <p>We’ll continue the conversation about open data, mapping and satellites at an <a href="">Open Geospatial Happy Hour</a> that we’re organizing with our friends from <a href="">Planet Labs</a> on Thursday evening. If you are interested in open geospatial data, please join us. You don’t need to be at the conference to attend.</p> <p>We look forward to meeting old and new geo friends while you are in Lisbon.

We work in the open. We have well over 100 public projects on GitHub and contribute to many others. We’ve helped dozens of NGOs, International Organizations, and Government Agencies to open source their code on GitHub.</p> <p>When we redesigned our website, we wanted to promote open source and to make it easy to find our code on GitHub. So we created GitHub cards.</p> <h3 id="whats-a-github-card">What’s a GitHub Card?</h3> <p>A GitHub card is a styled card that clearly calls out that this is an open source project, links to the project on GitHub, and shows statistics like forks and stargazers that show the depth of the community around that tool.</p> <figure class="align-center"> <img src="/assets/graphics/content/prose/github-card-example@2x.png" alt="GitHub card" width="370" height="172" /> <figcaption>A GitHub card example</figcaption> </figure> <p>GitHub cards are a visual way to promote open source and to make it easier for others to participate in our projects by requesting features or contributing code.</p> <h3 id="let-a-thousand-github-cards-bloom">Let a Thousand GitHub Cards Bloom</h3> <p>GitHub cards aren’t natively supported by GitHub. We built them into our site using a simple visual wrapper and a bit of code to pull live data from our public GitHub repos.</p> <p>We’d love to see more sites use GitHub cards. A simple visual flag for open projects across websites can reinforce how much of the web is built on open technologies. There are solid open source options for nearly any technology need. GitHub cards can make them more obvious.</p> <p>If you want to add GitHub cards to your own site, feel free to use our code.

From roads and rivers to internet and electricity lines, these intricate and vast networks exist everywhere we are. Considering that infrastructure is a broad classification, mapping out these different systems provides a unique insight into how these networks are dispersed onto the globe. Since the Connectivity Atlas was our first significant dive into <a href="">Mapbox GL</a>, we wanted to share some notes about our experience.</p> <h4 id="the-challenge-of-complex-data">The challenge of complex data</h4> <p>I started to build the map using <a href="">Mapbox Studio</a> importing each layer into Studio as a separate data source and styling each layer using <a href="">Carto CSS</a>. This workflow worked fine for a while, but over time might have led to hundreds of sources and styles pushing the limit of our Mapbox account and our organizational skills. This approach would also lead to performance issues as our data sets increase.</p> <p><img src="" /></p> <h4 id="rendering-vector-data-in-the-browser">Rendering vector data in the browser</h4> <p>We considered alternative workflows and ultimately decided to use Mapbox GL for various reasons.</p> <ul> <li>We like vector tiles (super crisp)</li> <li>We like rendering styles in the browser (it makes for faster styling / instant results)</li> <li>Better organization - we used a jekyll collection to add styles into a master JSON</li> </ul> <p><img src="" /></p> <h4 id="what-we-learned">What we learned</h4> <p>Vector tile platforms like GL allow for much faster rendering of complex data by using the graphics processor in the same way that a video game does. The tools for working with Mapbox GL are still limited. For example, we had to write our own tooltip functionality to expose the meta information in each layer. But we know the Mapbox folks are cooking up some new tools for GL, and we look forward to using GL for other projects.</p> <h4 id="open-infrastructure-data">Open Infrastructure Data</h4> <p>All of the data on the Connectivity Atlas is open and available for reuse. This is a collaborative project, and you can participate by sharing and suggesting data. This way we can produce a map of our profound inter-connectedness as well as an oddly beautiful web of global infrastructure.</p> 2015-05-01T02:00:00+00:00 Development Seed
