OS MasterMap® Topography Layer with Building Heights Attribute and OS Terrain 5 (DTM) - 3D Modeling
Ordnance Survey's most detailed mapping of Great Britain, delivered in layered DWG and DXF format ready for AutoCAD, Revit, Civil 3D and all major CAD platforms. Every building, boundary, road, path, waterway and structure - fully georeferenced to the British National Grid and structured into clean, named layers for immediate use in your design workflow.
Why Use OS MasterMap in CAD?
OS MasterMap Topography Layer is the definitive base map for site design, planning submissions and property analysis in the UK. Unlike raster images or traced PDF plans, our CAD files give you real vector geometry you can snap to, measure from and build on - exactly as your software expects it.
Clean, Layered Vector Data
Buildings, roads, vegetation, water, rail, landform and structures separated into named layers with accurate closed polylines. No broken lines, no stray geometry - tested and verified for compatibility with official Autodesk® software.
Includes DTM Height Data
OS Terrain 5 in ASCII plus DTM points (5 m grid values) in the same DWG/DXF format. Ideal for earthworks, drainage design and visualising site topography directly in your model. Optional 3D contours also available.
Building Height Attributes
OS Building Height Attribute data giving you ground level, eave height and roof height values for every building footprint. Generate massing models, check sight lines or assess overshadowing — possibly avoiding a separate survey.
Optional Raster Drape Layer
Select OS MasterMap Imagery (Aerial Data) or a MasterMap Raster Layer with or without text - delivered as a georeferenced GeoTIFF alongside your DWG/DXF.
Always current - OS MasterMap is updated on a six-week cycle, so your base plans reflect what's actually on the ground today.
Accepted for planning - OS MasterMap is the approved mapping for UK planning applications and Land Registry submissions. Using it means your site plans, location plans and block plans start from an authoritative, accepted source.
Licence Options
Flexible 1, 2 or 3-year licence terms with unlimited internal outputs at any scale. Cover exactly the area you need - from a single site to an entire local authority district.
Also Available in GIS Formats
Need the same data for QGIS, ArcGIS or web mapping? We supply OS MasterMap in GeoPackage, GML and Shapefile format, plus building footprints with height attributes as a separate layer - ready for spatial analysis, 3D visualisation or integration with your own datasets. The end user will need to style the GPKG, GML and SHP data.
