wradlib.georef.rect.get_radolan_coordinates

wradlib.georef.rect.get_radolan_coordinates(nrows=None, ncols=None, **kwargs)

Calculates x/y coordinates of RADOLAN projection of the German Weather Service.

Returns the 1D x,y coordinates of the RADOLAN projection for the given grid layout.

Parameters:

• nrows (int) – number of rows (460, 900 by default, 1100, 1500)

• ncols (int) – number of columns (460, 900 by default, 1400)

Keyword Arguments:

• wgs84 (bool) – if True, output coordinates are in WGS84 lon/lat format (default: False)

• mode (str) – ‘radolan’ - lower left pixel coordinates ‘center’ - pixel center coordinates ‘edge’ - pixel edge coordinates

• crs –

  Coordinate Reference System (CRS) of the DWD grid with spheroid model. Can be one of:

  • A pyproj.crs.CoordinateSystem instance

  • A cartopy.crs.CRS instance

  • A osgeo.osr.SpatialReference instance

  • A type accepted by pyproj.crs.CRS.from_user_input (e.g., EPSG code, PROJ string, dictionary, WKT, or any object with a to_wkt() method)

  • string “trig” to use trigonometric formulas for calculation (only for earth model - sphere).

  Defaults to None (earth model - sphere).

Returns:

radolan_ccords (tuple) – x and y 1D coordinate numpy.ndarray shape is (nrows, ) and (ncols, ) if mode=’radolan’ shape is (nrows, ) and (ncols, ) if mode=’center’ shape is (nrows+1, ) and (ncols+1, ) if mode=’edge’
