National Map Elevation Query API

The service from NASA's Goddard Space Flight Center provides topographic and terrain information to complement mapping locations. It returns the elevation for a specific location, specified as latitude and longitude. Measurements come from the USGS Seamless Elevation datasets. Where multiple elevation values are available, the service returns those from the data sources with the highest resolution.

API methods support submission of a request for one or more elevation values with each location specified as a latitude-longitude pair. The API returns the best-available measure for each location denominated in either feet or meters, as specified in the request.
