OS Maps API for Enterprise gives you a variety of map styles for business and public sector use – and there’s a free trial to get you started straight away.

 

In the outdoor stack, buildings in OS MasterMap Topography are in 2.5D. This means you’ll get a 3D appearance for 2D objects. 

 

We’ve incorporated different projections too. The API supports EPSG:27700 (British National Grid) and EPSG:3857 (Web Mercator). Users can request tiles in OGC KVP WMTS or RESTful ZXY, and in png format.
