The National Map Corps

TNMCorps is an online crowdsourcing mapping project with volunteers successfully editing structures in all 50 States and the U.S. Territories. 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!

The New TNMCorps Map Editing Application is Now Live! 

We’ve greatly appreciated your patience as we worked to develop our new map editing application and are pleased to announce that the wait is finally over! 

 

Changes

The new application will likely take some getting used to since we’ve introduced some significant changes, including adding three new recreation structure types and incorporating mapping-challenge-directed editing, both outlined below.  
 

As always, before diving in head-first, we highly recommend reading through our new User Guide and updated guidance documentation.
 

New Structure Types

If you’re an outdoors enthusiast tired of our same-old data (and even if you’re not!), you’ll be thrilled to know we’re now collecting and updating three new recreation-themed structure types:

  1. Campgrounds
  2. Trailheads
  3. Visitor centers

 

Mapping Challenges

Additionally, editing is now primarily directed via built-in mapping challenges focused on fixing specific errors, reviewing specific structures, or verifying data in a specific geographic area. The built-in mapping challenges should also make it easier for new users to find points to edit!  

 

Stay in Touch

To ensure you receive our correspondence, please add yourself to our mailing list if you’re not on it already. TNMCorps regularly interacts with volunteers directly via nationalmapcorps@usgs.gov. Interactions include virtual badges earned, and additional guidance. Also, our newsletters and announcements are sent from U.S. Geological Survey <info_update@info.usgs.gov>. This account is not monitored so please do not email us here. 

Note: If you're not receiving our messages, it's possible that they're getting caught by a spam filter. To ensure that our messages get through, add both emails to your email account's list of approved senders. We also recommend using a personal email account when signing up since institutional accounts (i.e., *.edu, etc.) tend to have universal filters that prevent our messages from coming through.
