Terrain Navigator Pro 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.

To activate this app, users need a licensed copy of the Terrain Navigator Pro desktop software version 9.2 or later.

To learn more about TNP, visit the Terrain Navigator Website at www.terrainnavigator.com.

The TNP mobile app uses the GPS built into the iPhone, 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 iPhone, 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.

•Near real-time sync between phone and TNP map software via Wifi or data connection like a 3G network.

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 iPhone device. Continued use of GPS running in the background can dramatically decrease battery life.

Love this and use it regularly on woodland ops. I just with the app would switch to a landscape mode when I rotate my phone. Make it so much easer to use in my carrier

I’m a happy user

I’ve been using the mobile app for a couple years. It has worked flawlessly for me on iPhones. Reliable track recording (when I remember to turn it on!). Reliable track guidance and GPS coordination when I am hiking using a previously downloaded track. Have had good experiences both in California and on trips in the UK. I’ve almost come to prefer it over using a Garmin GPS unit, at least when I am day hiking or just doing walk-abouts in county parks or other near urban settings.

Must Register Online

The app works great and syncs automatically with the desktop version to print out great looking maps. Very easy to use. You can even track a team of workers and share data almost instantly.
