How Accurate is onX?

We gather our data from a variety of sources, and we’re constantly checking to make sure our source is the most accurate available in all areas. We work with our data sources to make any corrections whenever errors are discovered.

Private Land Data

For the most part, you can expect the private property boundaries to be accurate to within 5-10 feet. However, this depends on the individual county and data source.

Some counties and data sources are much better at keeping their information up-to-date and accurate than others, but we work closely with them to correct errors when our customers encounter them.

Government Land Data

Our government land information is acquired from the county, state and federal level, so it will have the same level of accuracy as you will find elsewhere.

Your Location

The blue dot that indicates your location in onX is pulling your location data from the GPS receiver and mobile data network on your phone or tablet.

How Often is the Information Updated?

Each county formats their data differently and updates records on a different tempo. We are limited by the information the counties provide us. Typically, this is done every one-to-two years, depending on the availability of the data.

How Does onX Work When Outside Cell Service?

onX includes a feature called Offline Maps which allows you to save maps for use outside the cell network. Your smartphone or GPS-enabled tablet has built-in GPS receiver that will display your location and allow you to use the Map Tools and Tracker like normal when outside the cell network.
