OS MasterMap Topography Layer® - GIS | CAD - Overview

The OS MasterMap Topography layer is presented seamlessly with more than 500 Million real world objects – all uniquely identified - including roads, buildings, parks and waterways all managed and maintained by Ordnance Survey within one of the world’s largest spatial databases.

OS standard tiles are a huge 5km x 5km (and rather expensive) but on this page you can select an area as small as 100m x 100m - both saving £££s and not paying for data that is not required - we also have a function to rotate your area to save even more £££s.

Designed for use with:

GIS Software - GML | GeoPackage | GeoTiff
CAD Software - DWG or DXF

An optional Contour Layer is available | DXF format will be supplied

Some GIS experience is required for styling the GML and GeoPackage within a GIS package - The DXF and DWG formats for CAD and the GeoTiff are ready out of the box.

Options Info	Contours are generated from the OS Terrain® 5 using a third party application. They are not subject to Ordnance Surveys accuracy/specifications and are designed to provide a 2 dimensional guideline only. For 3D modeling it is best practice to use the DTM points rather as they have a Z(height) value attached to them
Licence Term	Please go to the Licence tab below
OS Terrain (Height)Accuracy	OS Statement: OS Terrain 5 has been measured against with GPS points in a range of sample areas to provide a root mean square error (RMSE) value for the height points in each geographic area; urban and major communication routes, rural, and mountain and moorland. Urban and major communication routes = 1.5 metres RMSE* Rural = 2.5 metres RMSE Mountain and moorland = 2.5 metres RMSE * Root mean square error. This is the average of the mean heights collected in a sample area. The contours are generated from the OS Terrain® 5 using a third party application. They are not subject to Ordnance Surveys accuracy / specifications and are designed to provide a 2 dimensional guideline only.
