Creates a latitude/longitude raster map.

r.latlong [-l] input=name output=name [--overwrite] [--verbose] [--quiet] [--qq] [--ui]

Example:

r.latlong input=name output=name

grass.script.run_command("r.latlong", input, output, flags=None, overwrite=False, verbose=False, quiet=False, superquiet=False)

Example:

gs.run_command("r.latlong", input="name", output="name")

DESCRIPTION

r.latlong creates a latitude (degree decimal) map, or longitude if the -l flag is used, from any map in any projection using PROJ library. This is an input to r.sun and i.evapo.potrad.

NOTES

The PROJ website.

TODO

Datum transform is not implemented, the same datum is taken as output.

EXAMPLE

g.region raster=elevation -p
r.latlong input=elevation output=latitude
