This document discusses and compares three low-cost, customizable navigation apps: DeLorme Street Atlas USA, Avenza Maps, and Google My Maps. DeLorme Street Atlas USA was previously used but was discontinued. Avenza Maps allows importing of custom maps for a one-time or annual fee. Google My Maps is free with some file size and data limits but has the benefits of no specialized software or internet access needed. The presentation raises questions about which app is best for navigation needs in remote, featureless areas.
