About this app

Developed for the U.S. Marine Corps, DNAm, the Discover Johnson Valley app is a public safety tool with which to inform visitors to the recently-established Shared Use Area (SUA) about its open or closed status. The app also utilizes smartphone Global Position System (GPS) technology to show users their location within the area, and alerts them when they have crossed into off-limits Combat Center property. Critically, once downloaded, cell service is not required for a users to track their location.

Other safety tools include base alerts and the ability of users to post GPS-tagged field tips and photographs about hazards like unexploded ordnance. Users can also use field tips and photographs to highlight interesting wildlife sightings.

In addition to serving as a public safety tool, the app includes extensive content about the Combat Center and its conservation activities; desert safety precautions; and interesting background on desert wildlife and habitat. Furthermore, Fun Facts pages offer an entertaining way to learn about the Combat Center and desert resources.

Packaged with beautiful and compelling imagery, as well as elegant design and an intuitive user interface, Discover Johnson Valley is a vital tool for users of the SUA, as well as anyone who has an interest in learning about the Combat Center and the base’s diverse desert wildlife and habitat.
