I need to find either some CPAN modules or at least a good math page to help me convert pixels to latlong on a map image. Given a map image with the dimensions of 200 x 200 and a known latlong center point, I am trying to compute the next center point if I pan the map 100 pixels in any direction.
Does anyone know of some Perl modules or even some reference pages to help me on my quest?
For purposes of documenting the quest. The Map projection is a Mercator Projection and I have scale lookups.
Everything I've learned in life can be summed up in a small perl script!
