wradlib.georef.raster.extract_raster_dataset

wradlib.georef.raster.extract_raster_dataset(dataset, mode='center', nodata=None)

Extract data, coordinates and projection information

Parameters:
  • dataset (gdal.Dataset) – raster dataset
  • mode (string) – either ‘center’ or ‘edge’
  • nodata (float) – replace nodata values
Returns:

  • values (numpy.ndarray) – Array of shape (nrows, ncols) or (nbands, nrows, ncols) containing the data values.
  • coords (numpy.ndarray) – Array of shape (nrows,ncols,2) containing xy coordinates. The array indexing follows image convention with origin at the upper left pixel (northup). The shape is (nrows+1,ncols+1,2) if mode == edge.
  • projection (osr object) – Spatial reference system of the used coordinates.
