[Xastir] georeferencing maps on osx?

[Gerry Creager N5JXS]

The grid lines are best viewed as approximations, not registration 
points!  Grass is a good starting point.  Sometime soon, Quantum GIS 
(qgis) will be there.  It's not there yet.

Check out http://openosx.com/grass/ for the Mac.

Also, last I checked, while there are a ton of "official" GRASS sites, 
the folks at Baylor, in Waco, TX, are still getting Army money to do 
development and enhancement...
