wradlib.georef.projection.reproject

wradlib.georef.projection.reproject(*args, **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:

• projection_source (osgeo.osr.SpatialReference) – defaults to EPSG(4326)

• projection_target (osgeo.osr.SpatialReference) – defaults to EPSG(4326)

• area_of_interest (tuple) – tuple of floats (WestLongitudeDeg, SouthLatitudeDeg, EastLongitudeDeg, NorthLatitudeDeg), only gdal>=3

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
