ecoscope.analysis.geospatial.datashade_gdf(gdf, geom_type, width=600, height=600, cmap=None, ds_agg=None, **kwargs)[source]#

Creates a raster of the given gdf using Datashader

Parameters:

  • gdf (geopandas.GeoDataFrame) – GeoDataFrame used to create visualization (geometry must be projected to a CRS)

  • geom_type (str) – The Datashader canvas() function to use valid values are ‘polygon’, ‘line’, ‘point’

  • width (int) – The canvas width in pixels, determines the resolution of the generated image

  • height (int) – The canvas height in pixels, determines the resolution of the generated image

  • cmap (list of colors or matplotlib.colors.Colormap) – The colormap to use for the generated image

  • ds_agg (datashader.reductions function) – The Datashader reduction to use

  • kwargs – Additional kwargs passed to datashader.transfer_functions.shade

Returns:

A tuple containing a PIL.Image raster and its EPSG

Return type:

4326 bounds
