The mapping crowd-sourcing program, known as The National Map Corps ( TNM Corps), encourages citizens to collect structures data by adding new features, removing obsolete points, and correcting existing data for The National Map database.
If you have access to the Internet and are willing to dedicate some time editing map data we hope you will consider participating!
Volunteers can now contribute data for all 50 states, Puerto Rico, and the US Virgin Islands! You do not need to live in available states to participate. Our editing guidelines explain how you can contribute data from anywhere.
WHAT WOULD I BE DOING IF I PARTICIPATE?
You would be using our online map editor to edit USGS structures data by updating existing features, adding new features, and removing obsolete features. You can choose what types of structure features to edit (from our list of structures ) and edit in any of the available states shown above!
