QUESTION
datashader 0.13.0, holoviews 1.14.4, geoviews 1.9.1., bokeh 2.3.2.
What I'm trying to doI'm trying to recreate a choropleth map with one color mapped to one category in a large GeoDataFrame using Datashader, following this example in the Pipeline page and this as well as this SO, which all differ slightly in their syntax, and all use points as the example, rather than polygons.
Reproducible code sampleBelow a small sample of the full dataset.
...ANSWER
Answered 2021-Jul-13 at 20:25Try agg=ds.by('category', ds.any())
, which will ignore polygons that overlap in any pixel. ds.count_cat('category')
is now an alias for ds.by('category', ds.count())
, but as of Datashader 0.12.1 you are no longer limited to just count
, and can e.g. use any
to discard information about overlaps.

Install spatialpandas
You can use spatialpandas like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
