PDL::GIS::Proj - PDL interface to the PROJ projection library.
For more information on the PROJ library, see: http://www.proj.org/ #line 36 "Proj.pm"
Returns a string with information about what parameters proj will actually use, this includes defaults, and +init=file stuff. It's the same as running 'proj -v'. It uses the proj command line, so it might not work with all shells. I've tested it with bash.
Signature: (lonlat(n=2); [o] xy(n); char* params)
PROJ forward transformation $params is a string of the projection transformation parameters.
Returns a pdl with x, y values at positions 0, 1. The units are dependent on PROJ behavior. They will be PDL->null if an error has occurred.
Ignores bad elements of $lat and $lon, and sets the corresponding elements of $x and $y to BAD
fwd_transform processes bad values. It will set the bad-value flag of all output ndarrays if the flag is set for any of the input ndarrays.
Signature: (xy(n=2); [o] lonlat(n); char* params)
PROJ inverse transformation $params is a string of the projection transformation parameters.
Returns a pdl with lon, lat values at positions 0, 1. The units are dependent on PROJ behavior. They will be PDL->null if an error has occurred.
inv_transform processes bad values. It will set the bad-value flag of all output ndarrays if the flag is set for any of the input ndarrays.
