Itinerant, i use a program called maptech, it allows me to make my own topo maps. with this program, i can download waypoints or complete routes onto the map and print it out. routes and waypoints will be fairly accurate, depends on how accurate the gps is on a given day. good day it will get you with ten feet, so as far as pinpointing an exact spot on the ground, it might be a little off, but it will still be close enough to be used as a guide. i have several gps units, mostly garmins, and i can download to the computer with all of them. hope this helps. sorry i did not reply to your email, but it did not contain a return address.
