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

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:

  • 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.

Then, the site will guide users through a process to analyze a specific hurricane image and answer questions, using a simplified technique for estimating the maximum surface wind speed of tropical cyclones.
