Hi, I'm looking for software on the Mac that will allow me to plan a backpacking trip through a national forest. I need software that will allow me to plan the trip's route and incorporate elevation data (either manually added or from a map set) for distance measurements and elevation profiles (graphs of distance vs. elevation). I won't be using a GPS, so support for one doesn't matter. I've found Terrain Navigator (http://maptech.mytopo.com/land/terrainnavigator/index.cfm) on Windows, but I can't seem to find anything on OS X that will work. Thanks in advance!
