I live in Utah and frequently hike in an area without any cell phone service and the IPAD with GPS has changed my whole way of enjoying the wilderness. I have an app with all of Utah’s topo maps loaded, and once I pick a route, my wife and I are to the trailhead, then off the trail. We can wander through meadow and valley with certainty as the App keeps our topo map updated with our orientation and location. Of course we can see the mountains to know our way back if it fails, but we can connect all the clearings and traverses in a path of least resistance.

That is very cool. Which model do you have? And does it come with 3g or is it one of the ones with no cell service?

Can that app also georeference images like geotiffs, so that you can use an aerial or satellite photo as a base map with the GPS, in addition to the topo?

I create my own topo/Google Earth composites using "Canvas", and would buy an iPad to use them in the field for archaeology if I knew I could get such an app.
