Vector tiles

OS Terrain 50 contour layers are supplied as a national vector tiles set in a single MBTiles file. This is a lightweight set of tiles that are efficient and fast to render in your software, provide high-resolution data, and which give a seamless experience when zooming in and out. The data is supplied in Web Mercator projection (ESPG:3857).

For guidance on using the product in vector tiles format, please see the Getting Started with Vector Tiles guide.
