TNMCorps Project Webpage

TNMCorps is an online crowdsourcing mapping project with volunteers successfully editing structures in all 50 States, Puerto Rico, and the U.S. Virgin Islands. As part of The National Map, 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 USGS National Structures Database, 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. Begin editing in your own hometown or anywhere in the U.S., Puerto Rico, and the U.S. Virgin Islands.


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

Citizen Science is What It's All About!

Citizen Science is a fun way for volunteers to contribute to a greater cause while pursuing their passions. Not to mention it also provides valuable hands-on experience. Our newsletter from May 2017 provides a good overview of citizen science.

TNMCorps even got a small shout-out in a recent Directions Mag article that describes various mapping citizen science projects. Reading through the article, it's neat to see how geography and citizen science are combining forces on some pretty intriguing projects.
