Welcome to the TNMCorps Q&A community!

I visited the National Map Corps web site to see if I could pull the crowd source data and I did not see a way to pull it. Is there a way, or is it only available through the National Map data?

Ultimately, the crowd-sourced data becomes part of the National Structures Dataset (NSD) which can be accessed via FTP for a full download:



via a map service: http://viewer.nationalmap.gov/example/services/serviceList.html

Does that help? The data you see at https://navigator.er.usgs.gov is in various stages of editing, and has not necessarily become a part of the NSD.

If you are looking for specific problem areas, a good tool to use (developed by a volunteer) is TNMExplorer at: https://nmc.onthemap.net/
