The National Map Corps

Help USGS update the National Map!
Add information to the National Map about man-made structures.

The National Map Corps enlists volunteers to collect and edit data about human made structures in an effort to provide accurate and authoritative map data for the USGS National Map and US Topo Maps. Using aerial imagery and base layers from The National Map, volunteers are editing 10 different structure types including schools, hospitals, post offices, police stations, and other important public buildings in all 50 States as well as Puerto Rico and the US Virgin Islands.
