Changelog

[0.10.3] - 2024-10-15

Fixes

• Downgrade minimum traitlets version to fix use with Colab. developmentseed/lonboard!687

[0.10.2] - 2024-10-10

Fixes

• Fix using TripsLayer.from_movingpandas with numpy v2.

[0.10.1] - 2024-10-08

Fixes

• Fix import when pandas not installed.

[0.10.0] - 2024-10-07

New!

• New TripsLayer for animating moving objects, which integrates with MovingPandas. See the Air Traffic Control example and the MovingPandas integration example.
• New ColumnLayer for rendering extruded cylinders. See the new ColumnLayer example.
• Removed required dependencies! geopandas, pandas, shapely, pyarrow, matplotlib, and palettable are now optional dependencies. Lonboard will still work out of the box with them, but they aren't required to use Lonboard. This gives Lonboard a smaller footprint and makes it easier to use in environments such as Pyodide.
• You can now draw bounding boxes on the map. This is exposed as the selected_bounds attribute on the Map object, stored as a two-dimensional bounding box (minx, miny, maxx, maxy).
• Improved documentation
• How to use Lonboard in pyodide, a Python environment that is fully running in your browser.
• Add linked maps example by @ATL2001 in developmentseed/lonboard!655
• Add troubleshooting doc by @kylebarron in developmentseed/lonboard!654
• Add longraph to showcase by @kylebarron in developmentseed/lonboard!595
• New Map.add_layer method for easily adding more layer(s) to an existing Map instance.
• Add highlight_color to change the color of auto_highlight by @kylebarron in developmentseed/lonboard!666
• Use deterministic colors in viz by @kylebarron in developmentseed/lonboard!621
• Categorical data filtering. The DataFilterExtension now has a filter_categories attribute that lets you filter categorical data on the map. by @kylebarron in developmentseed/lonboard!609

Breaking Changes

• The tooltip shown on hover was replaced with a side panel. You now must click on a geometry to view its attributes. By @vgeorge in developmentseed/lonboard!636

Fixes

• We've switched from storing list objects to storing tuple objects (e.g. the list of layers in a Map). The immutability of the tuple ensures that a any changes in the sequence of layers will be propagated to the frontend.Fixed in developmentseed/lonboard!620
• A class of bugs was fixed when using Arrow input, where the chunking structure of the main table did not match the chunking of accessors. Fixed in developmentseed/lonboard!644
• Fix reading from DuckDB with only geometry column by @kylebarron in developmentseed/lonboard!625
• Fix attribution by @vgeorge in developmentseed/lonboard!561

• 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.
