TNP System Requirements

Most modern Windows PCs will have sufficient features to meet the minimum system requirements of Terrain Navigator Pro. That said, here are some specifics:
  • Minimum Recommended Operating System: Windows 10 or 11 (32 or 64 Bit.)
    TNP is not compatible with Windows XP, Windows Vista, Windows RT, or Windows Mobile. We are no longer actively developing/testing TNP on Windows 7 or 8.

    For Mac compatibility, please see:

  • Minimum RAM: 4GB
    However, 8GB or more will increase the overall performance of your PC, which will in-turn increase the performance of TNP. 

  • Minimum Hard Drive Space: 12+GB
    With many data files, TNP can use up a bit of space on your hard drive. A full installation of a large state (such as Texas) could occupy an additional 10-12GB for the basic USGS topographic maps. Aerial/satellite photo images, street, and outdoor/contour map types require even more space if downloaded for offline use, but are typically read from the Internet as needed.

    TNP also maintains a local cache of map imagery that was recently viewed (or is likely to be viewed in the future.) A minimum 8GB cache is required; up to 64GB can be allocated.
  • Minimum Display Resolution: 1024x768
    While TNP will run on a lesser 800x600 display, certain interface elements will be cut off from view. We strongly recommend 1024x768 (and not using a larger font size) or higher.
  • Internet Access: REQUIRED (for Installation)
    In order to activate and validate your copy of Terrain Navigator Pro, the installation process must connect to our servers. This enables us to provide the latest fixes and enhancements available at the time of your installation. Plus many of the benefits of TNP come with the annual subscription, which consist of Internet-related features (such as aerial photo viewing/downloads, software upgrades, etc.)

    Starting with version 11, Terrain Navigator Pro is now primarily distributed via an Internet download. A reliable, high-speed Internet connection is required for this download process as it will entail many gigabytes of data, depending on the map area purchased. For those who lack high-speed Internet, DVDs are available for purchase (for a nominal fee.) However, an Internet connection is still required for registration validation.

    Once TNP is installed, you can use it off-line. Any maps and photos downloaded as "MapPacks" will remain available.
Is TNP compatible with the Windows Surface Pro or other tablet computers?
Yes. As long as the tablet is running the full version of Windows (and not Windows RT or Windows Mobile) the full PC software can be loaded on the tablet PC using a high-speed Internet connection or external DVD drive.

We also offer the TNP Mobile App for use on Android and iOS devices.

What can I do to improve the performance of TNP?
We recommend getting the best (highest performance) video display adapter that meets your budget. TNP is very graphic intensive - and a high-performance video display adapter can make a huge difference in the performance of the software. However, TNP will run just fine on any standard video device.

What GPS units do you recommend? Can I use the GPS built into my tablet?
For a list of GPSs compatible with TNP, please see:

TNP can also use any NMEA GPS (including those built into certain tablet computers) to record tracks/markers and display real-time position information on USGS topographic maps, aerial photos, etc. Some tablets running Windows 8 or later (and Windows location services) may need 3rd-party software to convert the internal GPS to the NMEA 0183 standard.

How many computers can I install Terrain Navigator Pro on?
Unless additional licenses are purchased, TNP can be installed by a single individual on one primary and one secondary computer. Typically, this is a desktop PC and a laptop PC used by the same person.
