FWIW, I think Mapsource is effectively obsolete. They stopped updating it in 2010. That's too bad, since I like it much better for on-road travel planning than BaseCamp.Oregon Hiker wrote:Mapsource downloading from Garmin seems to be a problem
I'm not going to waste any time detailing all the issues I have with it, but suffice to say if I was still a software tester and I let it be released as it is, I would have been fired. I would not recommend Nat Geo Topo even if it was free.PLC92084 wrote:then migrate to other applications (Nat Geo for example) if one wants more control/functionality.

I always thought the topo maps were made from aerial photography but the existence of the very old ones (late 1800's to early 1900's) belies that. Anyone know how they were made before photography in airplanes?CannondaleKid wrote: I've downloaded old archived USGS maps from the late 1800's to early 1900's for quite a bit of Arizona that had quite a few mines marked. But being that old, I've had little luck finding even traces of them.
Probably the hard way as in boots-on-the-ground surveying. The oldest one I just glanced at happened to be the area around Winslow and was dated 1883. It has a contour interval of 200'.Sredfield wrote:Anyone know how they were made before photography in airplanes?
