Base Map Tile Resources

The base map tile resources are responsible for requests with a variety of map tile types that differ in terms of the information they include and consequently also in terms of the visual style. A response delivers a single map tile image or a set of four, nine or sixteen map tiles encoded as text.

Check the info request of the base map tile resource to get a list of all the tile types and schemes supported.
