Wrap xarray-spatial functions as GeoViews operations #383

Open jbednar opened 4 years ago

jbednar commented 4 years ago

Datashader 0.8 added various geospatial analysis primitives like NDVI, bump mapping, viewshed calculation, and zonal statistics. How should we access those from within GeoViews? We can use .apply() to replay any steps we need, which should handle the arbitrary case, but it might be good to make operations for them to make it simpler.

In any case, we should probably document how to use them, somewhere in GeoViews, so that people realize this functionality is available.

Won't do this until https://github.com/holoviz/datashader/issues/835 is done.

These functions have moved from datashader to https://github.com/makepath/xarray-spatial , but it would still be great to make them easily invokeable from GeoViews.
