About Terrain Navigator Pro

Terrain Navigator Pro (TNP) provides an affordable and simple solution for professionals to collect and seamlessly transmit data from the field to the office. Use the TNP mobile app to map, find, collect, and share field data. Then, with a mobile connection, instantly share field data with the TNP desktop software to analyze GPS and GIS data at the office.

TNP serves a professional market, including search and rescue teams, law enforcement, foresters, surveyors, the oil and gas industry, and land managers. This mobile app is ideal for entry-level GIS applications and enables professionals to use the smartphone in their pocket instead of a consumer-grade GPS device (like a Garmin, Magellan or Delorme).

NEW: TNP Mobile is now compatible with the Trimble Leap GNSS Receiver, a high-accuracy receiver that pairs with Android devices. Now, you can collect field data at sub-meter accuracy. More at:

NEW: for TNP Enterprise customers - team tracking shows where your users are in near real time. Support for team projects which allow organizations to control data users can see and contribute to.

To activate this app, users need a licensed copy of the Terrain Navigator Pro desktop software version 9.2 or later. If you don’t own the TNP desktop software, please visit
The TNP mobile app uses the GPS built into the Android phone, so professionals can collect field data in areas without a cellular or data signal. In addition, users can download and store topographic, aerial, and street maps onto the phone for offline use and data display. Your data is stored on your Android phone, so there’s no need to have a network connection.

Got a Wi-Fi or data connection? Share your data in near real-time with colleagues at the office to streamline project workflows. The TNP app uploads data as it’s collected, so professionals with the same project open in the TNP desktop software can view the field data and collaborate to make accurate, on-the-spot decisions.

• Collect field data (markers, tracks, photos, videos, audio clips) in areas without a cellular or data signal.
• Near real-time sync between phone and TNP map software via Wifi or data connection like a 3G network.
• View data on topographic, aerial, and street maps downloaded to phone for offline use. Terrain Navigator Pro offers 1-meter aerial photos for the 48 contiguous United States. The seamless USGS topographic maps are based off 1:24K, 1:100K, 1:250K map scales. Alaska is 1:63K and 1:250K.
• Access a compass and other geo-information such as latitude/longitude, elevation, and direction on phone.

This app syncs to our award-winning Terrain Navigator Pro mapping software, which has been fine-tuned based on more than a decade of feedback from professionals who rely heavily on maps in the field. The TNP software provides access to an easily catalogued collection of USGS/US Forest Service topographic maps, including 1:24,000 (7.5 minute series), 1:100,000 and 1:250,000 scale as well as seamless, 1-meter resolution color aerial photos dating back to 2003, and up to the most recent National Agriculture Imagery Program (NAIP) aerial imagery available. The software supports GIS and CAD export and import, and provides access to advanced mapping tools, including: range rings by time and distance, area fills and line-of-sight height offsets, geo-pins, geo-tips, Public Land Survey System (PLSS), advanced address search, up-to-date street data, and more.

Notes: Terrain Navigator Pro is designed for your Android phones. Continued use of GPS running in the background can dramatically decrease battery life.

It's a great app.
