National map corps edits 25,000 manmade map features


US: Civilian volunteers are making significant additions to the US Geological Survey's ability to provide accurate mapping information to the public. Using crowd-sourcing techniques, the USGS' Volunteered Geographic Information (VGI) project known as The National Map Corps (TNMCorps) encourages citizen volunteers to collect manmade structures data in an effort to provide accurate and authoritative spatial map data for the National Geospatial Program’s web-based The National Map.

Since the beginning of The National Map Corps crowd-sourcing project, more than 25,000 structure or manmade feature updates have been submitted to improve the nation’s maps.

Structures being updated include schools, hospitals, post offices, police stations and other important public buildings.
