Requests to the Elevation API utilize different parameters based on whether the request is for discrete locations or for an ordered path. For discrete locations, requests for elevation return data on the specific locations passed in the request; for paths, elevation requests are instead sampled along the given path.
As is standard in all URLs, parameters are separated using the ampersand (&) character. The list of parameters and their possible values are denoted below.
•sensor (required) specifies whether the application requesting elevation data is using a sensor (such as a GPS device) to determine the user's location. Accepts true or false.
•Maps API for Business users must include valid client and signature parameters with their Elevation requests. Please refer to the Maps API for Business Web Services chapter for more information.
