The National Map Corps - Volunteer Map Editor

Volunteers collect structures data for The National Map using our online mapping application. Structures include schools, hospitals, post offices, police stations, cemeteries, and other important public buildings. Volunteers check the location of existing structure points against aerial imagery to verify that it is on the correct building, and confirm that the name and address information are correct using authoritative sources (e.g. official school district website). Volunteers also add missing structure points to the map, and remove points for structures that no longer exist. By updating and verifying structures data across all 50 states, Puerto Rico, and the US Virgin Islands, volunteers are making significant contributions to USGS National Structures Database, The National Map, and ultimately U.S. Topo Maps!

If you have access to the Internet and are willing to dedicate some time editing map data we hope you will consider participating! You do not need to live in any particular area to participate. Our editing guidelines explain how you can contribute data from anywhere.

Volunteers earn virtual badges for participating and are recognized for their contributions (with permission) via USGS and The National Map social media.
