Changelog

[0.7.0] - 2024-03-21

New!

• There's a new command-line interface (CLI)! Use the lonboard command to quickly visualize one or more data files readable by GDAL! For example: lonboard admins.geojson features.gpkg. By @kylebarron in developmentseed/lonboard!379
• Type hinting for constructors and from_geopandas method. This should make it easier to pass the correct parameters into layers. This has been tested to work in IDEs like VSCode, but unfortunately appears not to work in JupyterLab. By @kylebarron in developmentseed/lonboard!399

* Warn on missing CRS. One of the most common reasons that you might see an empty map is from accidentally visualizing data that is not in EPSG 4326 (longitude-latitude). We now emit a warning for data that doesn't have a CRS defined on the data. By @kylebarron in developmentseed/lonboard!395. * Lonboard is now on conda-forge! Install with conda install -c conda-forge lonboard. By @giswqs in developmentseed/lonboard!223 * Add PointCloudLayer. By @kylebarron in developmentseed/lonboard!396 * Add fly-to map action to "fly" the map to a new location. By @kylebarron in developmentseed/lonboard!408 * Docs showcase page by @kylebarron in developmentseed/lonboard!401 * Improve default colors in viz. We now attempt to apply some basic styling onto data passed into viz. This will likely further improve in the future. By @kylebarron in developmentseed/lonboard!389
