Crowdsourcing for the National Map

The U.S. Geological Survey (USGS) is testing out a new approach to its National Map Corps volunteer program and is launching a project for volunteers in Colorado to map man-made structures and facilities for updates to the National Map. “Even members of the public who can't tell a sandstone from a rhyolite but have Internet access can now help the USGS keep its popular maps up to date through our new experiment in crowdsourcing,” according to USGS director Marcia McNutt.
