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!
