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.4 library.  This is an input to r.sun and
       i.evapo.potrad.

NOTES

       The PROJ.4 website.

TODO

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