Terrain tiles are image tiles that contain hillshade mapping and contour lines. They include natural features such as vegetation.
Getting terrain tiles
You can begin making terrain tile requests after you get a session token. Because a session token applies to the entire session, you don't have to specify the map options with your tile requests.
The following code sample demonstrates a typical session token request for terrain tiles.
curl -X POST -d '{ "mapType": "terrain", "language": "en-US", "region": "US", "layerTypes": ["layerRoadmap"] }' \ -H 'Content-Type: application/json' \ "https://tile.googleapis.com/v1/createSession?key=YOUR_API_KEY"
You get terrain tiles by making an HTTPS GET request, as shown in the following example.
curl "https://tile.googleapis.com/v1/2dtiles/z/x/y?session=YOUR_SESSION_TOKEN &key=YOUR_API_KEY
Example tile request
Consider the following example, which requests a single terrain tile with zoom level 10, with x and y coordinates of (192, 401).
curl "https://tile.googleapis.com/v1/2dtiles/10/192/401?session=YOUR_SESSION_TOKEN --output /tmp/example_tile.png&key=YOUR_API_KEY"
There is no response message from the server in this example. Instead, the tile just downloads to a local file.
