Getting Started

The Google Maps Elevation API provides elevation data for all locations on the surface of the earth, including depth locations on the ocean floor (which return negative values).

Sample request and response

You access the Google Maps Elevation API through an HTTP interface, with requests constructed as a URL string, using latitude/longitude coordinates to identify the locations or path vertices. Requests must include your API key.

The following example requests the elevation for Denver, Colorado, the "Mile High City", in JSON format:

https://maps.googleapis.com/maps/api/elevation/json?locations=39.7391536,-104.9847034&key=YOUR_API_KEY

You can test this by entering the URL into your web browser (be sure to replace ‘YOUR_API_KEY’ with your actual API key). The response includes the elevation at that point, in meters, along with the resolution value (the maximum distance between data points from which the elevation was interpolated, in meters).

View the developer's guide for more information about building request URLs and available parameters and understanding the response.

Below is a sample response, in JSON:

{
   "results" : [
      {
         "elevation" : 1608.637939453125,
         "location" : {
            "lat" : 39.73915360,
            "lng" : -104.98470340
         },
         "resolution" : 4.771975994110107
      }
   ],
   "status" : "OK"
}

Start coding with our client libraries

Client libraries make developing with the Google Maps web service APIs easier by providing simple, native implementations of common tasks, such as authentication, request throttling and automatic retry. The Google Maps Elevation API is available in the Java Client, Python Client, Go Client and Node.js Client for Google Maps Services.
