SUBROUTINES
fwd_transform($lon(pdl), $lat(pdl), $params)
Proj4 forward transformation $params is a string of the projection transformation parameters.
Returns two pdls for x and y values respectively. The units are dependant on Proj4 behavior. They will be PDL->null if an error has
occurred.
BadDoc: Ignores bad elements of $lat and $lon, and sets the corresponding elements of $x and $y to BAD
inv_transform($x(pdl), $y(pdl), $params)
Proj4 inverse transformation $params is a string of the projection transformation parameters.
Returns two pdls for lat and lon values respectively. The units are dependant on Proj4 behavior. They will be PDL->null if an error has
occurred.
BadDoc: Ignores bad elements of $lat and $lon, and sets the corresponding elements of $x and $y to BAD
get_proj_info($params_string)
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.
