.zonal

internal

Processing of large-in-memory/large-on disk rasters and spatial
vectors using 'GRASS GIS' <https://grass.osgeo.org/>. Most functions in
the 'terra' package are	recreated. Processing of medium-sized and smaller
spatial objects will nearly always be faster using 'terra' or 'sf', but
for large-in-memory/large-on-disk objects, 'fasterRaster' may be faster.
To use most of the functions, you must have the stand-alone version (not
the 'OSGeoW4' installer version) of 'GRASS GIS' 8.0 or higher.
