For more information on the proj library, see: http://www.remotesensing.org/proj/AUTHORJudd Taylor, Orbital Systems, Ltd. judd dot t at orbitalsystems dot comDATE18 March 2003CHANGES1.32 (29 March 2006) Judd Taylor - Getting ready to merge this into the PDL CVS. 1.31 (???) Judd Taylor - Can't remember what was in that version 1.30 (16 September 2003) Judd Taylor - The get_proj_info() function actually works now. 1.20 (24 April 2003) Judd Taylor - Added get_proj_info(). 1.10 (23 April 2003) Judd Taylor - Changed from using the proj_init() type API in projects.h to the - proj_init_plus() API in proj_api.h. The old one was not that stable... 1.00 (18 March 2003) Judd Taylor - Initial versionCOPYRIGHT NOTICECopyright 2003 Judd Taylor, USF Institute for Marine Remote Sensing (judd@marine.usf.edu).

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. perl v5.14.2 2012-05-30 Proj(3pm)
