Mapping Challenges

Mapping Challenges are a fun program that encourages users to edit a specific feature type within a geographic area.  Any volunteers who edit this feature type within the geographic area receive special recognition on TNMCorps' websites and social media pages. Areas chosen for a mapping challenge are directly tied to USGS's US Topo Map production.

Ongoing Challenges

We currently have two challenges open:

  1. Post Offices in Virginia, West Virginia, and Maryland; and
  2. NEW!! All features in the US Pacific Territories.

See the news briefs in the related content below for updates on each.
