If your maps aren't already georef'd, it's troublesome to find the correct values to use. For reference, the four values are: * meters per pixel in X direction * meters per pixel in Y direction * UTM X of top left map corner * UTM Y of top left map corner You'll note that there's no UTM zone. This doesn't matter on a small enough scale. I wrote a collection of scripts that triangulate the correct set of values from three lat/lon->x/y pairs, but they're nowhere near usable for the general public. If you're handy with maxima (the mathematica clone) let me know and I'll ship them your way. ------------------------------------------------------------------------------ What Every C/C++ and Fortran developer Should Know!
