USGS Continues to Expand Crowdsourcing Project

摘要

The U.S. Geological Survey (USGS) continues to expand its crowdsourcing activities for geographic data and is seeking volunteers nationwide to contribute structures information. The mapping crowdsourcing programme, known as 'The National Map Corps' (TNMCorps), 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.
