-------- Original Message --------I am studying some early nineteenth century maps by Aaron Arrowsmith that show projection grids (graticules), but do not state what projection was used. 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?
