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. Law enforcement entities in Kentucky and Tennessee, and
  2. NEW!! Schools with no edit history in Virginia, West Virginia, Maryland, and Washington, D.C.

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