Our map products overlay the best hiking and exploration topographic maps on top of an OpenStreetMap background, making the maps available as a mobile app with no reliance on cellular service. The result is a rich, reliable, geographically accurate experience.
Tom Harrision Maps publishes the best full-color, shaded-relief topographic maps for hiking, backpacking, and mountain biking in Parks, Forests, and Wilderness Areas in California. We have worked out a licensing arrangement with Tom Harrison Maps to use their detailed and attractive print maps for our apps.
