Description

Datashader 0.16.0 is a significant release adding support for rendering GeoPandas GeoDataFrames directly rather than having to convert them to SpatialPandas first. Support for GeoPandas geometry types in Datashader Canvas functions is as follows:

  • Canvas.line: LineString, MultiLineString, MultiPolygon, Polygon
  • Canvas.point: MultiPoint, Point
  • Canvas.polygons: MultiPolygon, Polygon

There is also support in Canvas.line for a new data type which is a 2D xarray.DataArray (within an xarray.Dataset) containing the coordinates of multiple lines that share the same x coordinates.

The DataShape package is now vendored in Datashader as it has not been maintained for a number of years and is not accepting updates.

Thanks to new contributor @J08ny and regular contributors @Hoxbro and @ianthomas23.
