Where do you get your trail data?
We get our data from a variety of government sources and motor vehicle use maps (MVUM's) from state and federal agencies such as the U.S. Forest Service, the U.S. Geological Survey, Bureau of Land Management, National Parks, and more.
We also source data from private organizations responsible for managing or maintaining trail networks and OHV parks/other areas throughout the country, and utilize our Trail Guide program to source accurate data from offroaders just like you.
Who can see my saved data?
Only you.
While you have the option to export or share anything you create in the Offroad App with another Offroad user, any Markups you save in the Offroad App are only visible to you and anyone you've shared them with.
How often is parcel data updated?
We update Private and Government land data every one-to-two years and rely on the counties and local data sources to keep their information updated and accurate. It takes a great deal of time and effort to gather the data, format it for use in our maps, double-check everything, and finally release the update, so we appreciate your patience.

How accurate are parcel boundaries?
Property boundaries are usually accurate within 5 – 10 feet, depending on the county in question.
How often is the satellite imagery updated?
Satellite imagery is 4 years old on average; it's intended to give you a general idea of the terrain, but doesn't necessarily reflect current conditions on the ground.
How accurate is my location, elevation, and the Tracker?

What coordinate datum does onX Offroad use?
All onX products utilize the World Geodetic System 1984 (WGS 84), a 3-dimensional coordinate reference frame used to establish latitude, longitude and height/elevation for navigation purposes.
