Mapping Challenges

By The National Map Corps

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.
