wradlib.zonalstats.ZonalDataPoint

class wradlib.zonalstats.ZonalDataPoint(src, trg=None, buf=0.0, srs=None, **kwargs)

ZonalData object for source points

Parameters:
  • src (sequence of source points (shape Nx2) or) – ESRI Shapefile filename containing source points
  • trg (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) Points will be considered inside the target if they are contained in the buffer.
  • srs (object) – OGR.SpatialReference will be used for DataSource object. src and trg data have to be in the same srs-format

Examples

See ZonalData.
