wradlib.georef.projection.reproject

wradlib.georef.projection.reproject(*args, **kwargs)

wradlib.georef.projection.reproject(obj: Dataset, **kwargs)

wradlib.georef.projection.reproject(obj: DataArray, **kwargs)

Transform coordinates from a source projection to a target projection.

Call signatures:

reproject(C, **kwargs)
reproject(X, Y, **kwargs)
reproject(X, Y, Z, **kwargs)

C is the np array of source coordinates. X, Y and Z specify arrays of x, y, and z coordinate values

Parameters:

• C (numpy.ndarray) – Array of shape (…,2) or (…,3) with coordinates (x,y) or (x,y,z) respectively

• X (numpy.ndarray) – Array of x coordinates

• Y (numpy.ndarray) – Array of y coordinates

• Z (numpy.ndarray) – Array of z coordinates

Keyword Arguments:

• src_crs –

  Coordinate Reference System (CRS) of the coordinates. 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.from_user_input (e.g., EPSG code, PROJ string, dictionary, WKT, or any object with a to_wkt() method)

  Defaults to EPSG(4326).

• trg_crs –

  Coordinate Reference System (CRS) of the coordinates. 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.from_user_input (e.g., EPSG code, PROJ string, dictionary, WKT, or any object with a to_wkt() method)

  Defaults to EPSG(4326).

• area_of_interest (tuple) – floats (WestLongitudeDeg, SouthLatitudeDeg, EastLongitudeDeg, NorthLatitudeDeg), defaults to None (no area of interest)

Returns:

• trans (numpy.ndarray) – Array of reprojected coordinates x,y (…,2) or x,y,z (…,3) depending on input array.

• X, Y (numpy.ndarray) – Arrays of reprojected x,y coordinates, shape depending on input array

• X, Y, Z (numpy.ndarray) – Arrays of reprojected x,y,z coordinates, shape depending on input array
