Crowd-sourcing the national map: Now a national effort

from USGS via GIS User

The USGS continues to expand its crowd-sourcing of geographic data and is seeking volunteers nation-wide to contribute structures information. The mapping crowd-sourcing program, known as The National Map Corps, encourages citizens to collect structures data by adding new features, removing obsolete points and correcting existing data for The National Map database. Structures being mapped in the project include schools, hospitals, post offices, police stations and other important public buildings. more
