Web Map Service (WMS)

This is a simple interface for dynamically generating map images including layers and areas of interest from a database. Each request from the user is called a map transaction. These take time to register, access the database and then create and serve raster tiles. OS OnDemand WMS does this in less than two seconds.

OS MasterMap Topography Lambeth

Web Map Tile Service (WMTS)

This generates predefined map images from a cache. Rather than having to get features from the database like the WMS, mapping application programming interfaces (APIs) use preconfigured and rendered map tiles. The WMTS includes a consistently styled zoom map stack which enables easier interpretation of mapping between zoom thresholds. It can be accessed using OGC WMTS Tile Requests, via the API and/or using XYZ Style Tile Requests.
