What Are the Benefits Included in the Annual Subscription?

Terrain Navigator Pro is offered as an annual "software as a service" subscription which includes a host of benefits. This annual service subscription ensures that TNP is maintained constantly with the best features and maps. Throughout the subscription period, these updates and services include:

Aerial OrthoPhotos:

Aerial OrthoPhotos are downloaded automatically from our servers when selected. With the exception of Alaska and parts of Nevada, the entire U.S. is available in a color photo that was taken within the last 2-3 years. These photos are freely distributable (within the terms of the licensing agreement) for use in reports, section maps, websites, and publications. 

Alternate Edition Photos and Maps:
Nearly every map type in TNP contains one or more alternate edition. For topographic maps these consist of shaded relief maps whereas alternate editions of aerial photo consist of different years, and may include black and white or infra-red imagery. We continue to expand and improve the quality and quantity of these alternate editions each year.

Satellite Imagery, Street Maps/Layer, and Terrain Contour Maps:
Highly detailed maps and images (down to 1:1,127 scale) are available as part of the current version of Terrain Navigator Pro. This includes the street layer superimposed over photos and maps that lack current road information.  These maps and layers are constantly being updated and are not available once the subscription lapses.

Map and Photo Updates:
We check with the various mapping agencies to ensure that the most current maps and photos available are included in Terrain Navigator Pro. As long as your subscription is active you are entitled to these updates as they become available.

MapPacks can be created to allow TNP to run without an Internet connection. However, use of these MapPacks is suspended when the subscription has expired.

Custom Maps:
Starting with version 11 of Terrain Navigator Pro, maps in GeoTIFF format can be used and displayed. However, this functionality becomes disabled once the subscription has expired.

Mobile App Synchronization:
Connectivity between the Terrain Navigator Pro Mobile App and the desktop software is accomplished through cloud synchronization over the Internet. Your subscription keeps this connection in tact.

Team Tracking:
Those with more than one user account as part of their TNP team (and an active subscription) can track the positions of each teammate within the organization using Team Tracking.

Software Upgrades:
Three to four times each year, we release upgrades to the Terrain Navigator Pro software. So long as the subscription remains current, you will receive these upgrades at no charge.

Other Updates:
