We have compiled a set of C routines as shared libraries which can be
called from within IDL to do all those conversions. USGS has a package
called PROJ.4 which is cartographic projection software which can be
downloaded from their website at
http://kai.er.usgs.gov/ftp/PROJ.4/proj.html. Send me an email if you'd
like more information on our implementation.
