wradlib.zonalstats.DataSource

class wradlib.zonalstats.DataSource(data=None, srs=None, name='layer', source=0, **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.
