USGS Report on Crowdsourcing for The National Map

Structures Data Collection for The National Map using Volunteered Geographic Information is avilable in PDF (2.7 Mb) from USGS.

The U.S. Geological Survey (USGS) has historically sponsored volunteered data collection projects to enhance its topographic paper and digital map products. This report describes one phase of an ongoing project to encourage volunteers to contribute data to The National Map using online editing tools. 

Lessons learned:

• simplifying editing tasks and the user interfaces,
• stressing to volunteers the importance of adding structures that are missing, and
• emphasizing the importance of conforming to editorial guidelines for formatting names and addresses of structures.
