Function Details

_run_starspan_zonal(geom, rasterds, pixprop=0.5)

Consider this a 'private' method .. dont call directly, use zonal_stats() instead Runs starspan and returns a ZonalStatsCache object

zonal_stats(geom, rasterds, read_cache=True, cache_only=False, pixprop=0.5)


Given a GEOSGeometry and a RasterDataset,
compute the zonal stats and return json like
 { 'raster': 'elevation', 'stats': {'sum': 10234.2, 'mean': 12.4}}
result will be stored in cache
 and cache value is returned if read_cache

Variables Details

RASTER_TYPES

Value:

"continuous", "continuous", ("categorical", "catgorical"),
