- Tips For Use
The Tom Harrison: San Gorgonio Wilderness app for Android is a personal navigation and tracking application, intended for use by outdoor enthusiasts. The application displays the San Gorgonio Wilderness map from Tom Harrison Maps, overlayed on top of the OpenStreetMap map. Using the GPS in your phone or tablet, your position on the map is shown, and your track can be logged.
The Tom Harrison: San Gorgonio Wilderness app uses OpenStreetMap map data, and the osmdroid software library. Tom Harrison map data is © Tom Harrison Maps. OpenStreetMap map data © OpenStreetMap contributors, CC-BY-SA.
No single navigation aid is a replacement for experience and preparation. All safe backcountry travel practices should be followed.

Tips For Use:

- Saving Battery Life: When using the app in the backcountry, you're not going to see many cell towers, so why waste battery trying to contact them? On Android phones, go to the phone settings, in the Wireless menu, turn on Airplane Mode. This will turn off the cellular and WiFi radios, but allow the GPS to function, extending your battery life significantly!
- Recording The Track of a Trip: Whether you are planning on backpacking the Pacific Crest Trail, or driving an old forest road, it is nice to have a track of your journey for later viewing. While you can just leave the track record on for an entire multi-day trip, it will save battery overnight, and be more manageable later, if you record your track in segments. For instance, one track record per day often works quite well. At the end of the day, press the menu button, select Tracks, and Save Track. Once you have named and saved your track, clear the track.
