wradlib.zonalstats.ZonalDataPoly#

class wradlib.zonalstats.ZonalDataPoly(src, trg=None, buf=0.0, srs=None, **kwargs)[source]#

ZonalData object for source polygons

Parameters:

  • src (sequence or str) – sequence of source polygons (shape NxMx2) or ESRI Shapefile filename containing source polygons

  • trg (sequence or str) – sequence of target polygons (shape Nx2, num vertices x 2) or ESRI Shapefile filename containing target polygons

Keyword Arguments:

  • buf (float) – (same unit as coordinates) Polygons will be considered inside the target if they are contained in the buffer.

  • srs (osgeo.osr.SpatialReference) – OGR.SpatialReference will be used for DataSource object. src and trg data have to be in the same srs-format

Examples

See ZonalData.
