An OGC Web Map Tile Service (WMTS) serves digital maps in the form of predefined image tiles. The OGC WMTS specification standardizes how a WMTS server publishes the available images, as well as how the images are exchanged between a WMTS server and a WMTS client.
Since the structure of the image data is strictly defined, visualizing data from a WMTS server is usually much more efficient than from a WMS server.
The LuciadRIA WMTS client API provides a WMTS model, and API to inspect the capabilities of a WMTS server.
