Details of a crowd-sourcing effort is being touted by the USGS and partners in the National Map. The agency is looking for crowd participants to help enhance the National Map and currently has some 18 States open for data editing, updates, and new features. Participants will become part of the National Map Corps. Collaborative pilot projects in Colorado were recently used to test the concept of crowd-sourcing. Over a trial period of ten months, 143 volunteers collected, improved, or deleted data on more than 6,400 structures in Colorado. The states in the first expansion of TNMC are: Arkansas, Alaska, Colorado, Delaware, Georgia, Idaho, Maryland, Michigan, Montana, North Dakota, New Jersey, New Mexico, Ohio, Oregon, South Carolina, Utah, Washington, West Virginia
