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.
