The Elevation API is a service that returns elevation data for a location on the earth, or sampled elevation data along paths.
Why use the Elevation APIWith the Elevation API, you can develop applications to support your customers with elevation-sensitive activities, positioning applications, or low-surveying applications that include elevations and elevation changes along routes. For example, you can provide elevation gain and loss data to enhance a sports application for activities such as hiking, biking, or scuba diving.
What you can do with the Elevation APIWith the Elevation API, you can include elevation data in your applications or on a map. For example:
The Elevation API accepts a request as an encoded URL with latitude/longitude coordinates provided as either discrete locations, or as a series of locations along a path. This request, for example, queries elevation for the center of Denver, Colorado, specifying a return in JSON format.
https://maps.googleapis.com/maps/api/elevation/json ?locations=39.7391536%2C-104.9847034 &key=YOUR_API_KEY
The service derives the elevation for the provided coordinates. It also interpolates elevation for a location without elevation, providing an average returned from the four nearest locations that do provide elevation data. Finally, it determines the overall resolution for the location.
ResourcesThe following table summarizes the resources available through the Elevation API along with the data it returns.
Data resources Data returned Return format Latitude/longitude coordinatesYou can provide data as a set of one or more locations, or as a series along a path. You can also provide encoded coordinates. Pass up to 512 coordinates.
The Elevation API provides elevation in meters relative to the local mean sea level (LMSL). Elevation can be returned as positive or negative values as indicated below:
