TNMCorps Project Webpage
The National Map Corps (TNMCorps) is an online crowdsourcing mapping project with volunteers successfully editing structures data in all 50 States, Puerto Rico, and the U.S. Virgin Islands. Structures include schools, hospitals, post offices, police stations, cemeteries, and other important public buildings. By updating and verifying structures data, volunteers are making significant contributions to the USGS National Structures Dataset, The National Map, and ultimately U.S. Topo Maps!
Anyone with an interest in contributing can volunteer. It is easy to sign up and get started! All you need is access to the internet, an email address, and a willingness to learn. “How to” documentation including a comprehensive User Guide and a Quick Start Guide will have you up and editing quickly.
Volunteers earn virtual badges for participating and are recognized for their contributions (with permission) via USGS and National Map social media.
