wradlib.georef.projection.create_osr

wradlib.georef.projection.create_osr(projname, **kwargs)

Conveniently supports the construction of osr spatial reference objects

Currently, the following projection names (argument projname) are supported:

“aeqd”: Azimuthal Equidistant

needs the following keyword arguments:

  • lat_0 (latitude at projection center),

  • lon_0 (longitude at projection center),

  • x_0 (false Easting, also known as x-offset),

  • y_0 (false Northing, also known as y-offset)

“dwd-radolan” : RADOLAN Composite Coordinate System

  • no additional arguments needed.

Polar stereographic projection used by the German Weather Service (DWD) for all Radar composite products. See the final report on the RADOLAN project [DrWeigl et al., 2004] for details.

Parameters:
  • projname (str) – “aeqd” or “dwd-radolan”

  • kwargs (dict) – depends on projname - see above!

Returns:

output (osgeo.osr.SpatialReference) – GDAL/OSR object defining projection
