Is there an API for accessing The National Map data?
An Application Programming Interface (API) is a way for developers to interface with data.
The National Map (TNM) has one API (TNMAccess) that provides access to all TNM downloadable products that are available through The National Map Download Client.
Developers can use HTTP GET and POST requests to directly access products, or use the light graphical interface on the API page to generate queries to send to the API.
