wradlib.zonalstats.DataSource(data=None, srs=None, **kwargs)¶ DataSource class for handling ogr/gdal vector data
DataSource handles creates in-memory (vector) ogr DataSource object with one layer for point or polygon geometries.
Parameters: - data (sequence of source points (shape Nx2) or polygons (shape NxMx2) or) – ESRI Shapefile filename containing source points/polygons
- srs (object) – ogr.SpatialReferenceSystem SRS describing projection of given data
Warning
Writing shapefiles with the wrong locale settings can have impact on the type of the decimal. If problem arise use LC_NUMERIC=C in your environment.
