wradlib.zonalstats.ZonalDataPoly¶

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

ZonalData object for source polygons

Keyword Arguments:
Parameters:	src (sequence of source polygons (shape NxMx2) or) – ESRI Shapefile filename containing source polygons trg (sequence of target polygons (shape Nx2, num vertices x 2) or) – ESRI Shapefile filename containing target polygons
	buf (float) – (same unit as coordinates) Polygons 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

`dump_vector`(filename[, driver, remove])	Output source/target grid points/polygons to ESRI_Shapefile
`get_isec`(idx)	Returns intersections
`get_source_index`(idx)	Returns source indices referring to target polygon idx
`load_vector`(filename)	Load source/target grid points/polygons into in-memory Shapefile

`count_intersections`	Returns number of intersections
`isecs`	Returns intersections
`srs`	Returns SpatialReferenceSystem object
