Bianco <[log in to unmask]> To: 'Maps, Air Photo, GIS Forum - Map Librarianship' <[log in to unmask]> Dear all, I’m trying to use Tomas Bayer’s SW (W7 32 and 64 bit), but I don’t know how to launch it. When I launch the program, nothing happen. Is there anyone that had my same troubles?

I was wondering if someone has developed software to ascertain map projections based on the lines of the grid. I would think that it would be fairly easy to develop something like this, but have not been able to turn up anything via Google. Any leads? David Allen (Stony Brook University, Emeritus)
