OS Vector Tile API

OS Vector Tile API is a vector tile service providing detailed Ordnance Survey data as a customisable basemap. It can be used with most web mapping libraries including Mapbox GL JS, Leaflet, OpenLayers and ArcGIS API for JavaScript. Vector Tiles have the benefit of being optimised for use across the internet and are great for building interactive web maps. You can zoom, pan, rotate, tilt and even extrude 3D buildings.

You have a choice between using Ordnance Survey styles or creating your own. You can customise the content and the style to create a map that perfectly meets your needs. Design a map that matches your brand or get creative and add some cartographic flair to your application.

With OS Vector Tile API you can also select and interact with the individual map features.

OS Vector Tile API is available in two projections; British National Grid for GB data and Web Mercator which is a global coordinate system.

The OS MasterMap Water Network Layer product (also referred to as OS MasterMap Networks – Water Layer) will become End of Life on 31 March 2026. As of this date, access to the product will be removed from the OS Vector Tile API. Further information is available on the End of Life Product Notices page on the OS Download Products' Documentation site.
