The U.S. Geological Survey is asking volunteers to help map man-made structures and facilities, such as schools and fire stations, in the state of Colorado then, in a few months, the United State. Using an internet mapping application, volunteers can help the USGS update The National Map by correcting or adding information about structures nearby.

"Correctly locating and identifying fire stations, police stations, schools, and hospitals not only makes USGS maps more useful, but can literally save a life," said USGS Director Marcia McNutt.
