USGS National Map Corps

# USGS National Map Corps The National Map Corps (TNMCorps) is the U.S. Geological Survey's citizen-mapping program: an online crowdsourcing project whose volunteers edit and verify structure data - schools, hospitals, post offices, fire and EMS stations, campgrounds, trailheads, and more - across all US states and territories. Volunteer edits feed the USGS National Structures Database, The National Map, and ultimately the US Topo maps used by agencies and the public. ## What You'll Do - Sign up on the TNMCorps editor and work through the user guide and quick-start documentation - Verify, correct, add, or remove structure points using aerial imagery and authoritative sources - Join themed mapping challenges that direct volunteers to areas needing attention - Earn recognition through the program's virtual badges as your accepted edits accumulate ## Who Should Apply Per USGS, 'Anyone with an interest in contributing can volunteer' - all you need is 'access to the internet, an email address, and a willingness to learn.' It is a good fit for students into geography, GIS, and public data who want flexible, self-paced federal volunteering they can do in short sessions. ## Outcomes Volunteers make verifiable contributions to official government map products - edits that appear in nationally published data - while building GIS-adjacent skills that transfer to geography, urban planning, and data careers. Participation is year-round with no deadlines, and the program's newsletter documents active challenges and volunteer accomplishments.
