US Public Lands – How Accurate are the Maps?

The public domain source of our data is from the Protected Area Database (PAD-US 2.0) of the U.S. Geological Survey.

Please note, the USGS PAD-US database contains the “most up-to-date aggregation of Federal lands and waters” available, but this database is still evolving and some locations may not be listed and others may not have precisely accurate boundaries. Resolution across the nation may vary. And always remember – there may be private unmapped inholdings within any public lands – so always pay attention to local signage, indications, and information.
