📐 OS Professional Data – CAD Data | Mapping

OS Professional Data consists of survey-grade Ordnance Survey MasterMap® products delivered in editable CAD and GIS formats (DWG, DXF, SHP, GeoPackage). It’s designed for architects, engineers, planners and GIS professionals who require accurate, layered base mapping.

Professional datasets are available in DWG, DXF, SHP (Shapefile) and GeoPackage formats — all projection-ready and compatible with most CAD and GIS software.

“Site-centred” means the map extract is tailored to your specific area of interest, ensuring your project location sits at the centre of the dataset rather than on an edge.

Data is delivered digitally by email, typically within 20–30 minutes of purchase, 7 days a week.

UK Map Centre has been a trusted Ordnance Survey Premium Partner for over 20 years, supplying licensed professional mapping data across Great Britain.

CAD OS MasterMap is the most detailed editable vector data from OS, showing individual buildings, boundaries, and physical features — ideal for detailed design and engineering. VectorMap Local (1:10,000) is a simplified, generalised backdrop suited for context and asset mapping.

CAD OS MasterMap (DWG/DXF) is the best choice for design workflows — fully layered, editable vector data that integrates seamlessly with BIM, planning and CAD drawing systems.

OS MasterMap Tiles are true-orthorectified raster tiles (1 km × 1 km), ideal for large-area backdrops, planning zones, and GIS overlays.

OS Height Data (DTM) is a Digital Terrain Model providing elevation information. It’s used for contouring, flood modelling, visibility analysis, drainage and 3D terrain modelling in CAD and GIS.

VectorMap Local (1:10,000) — a clean, generalised base ideal for context mapping, asset registers and background plans.

OS Professional Data works with AutoCAD, MicroStation, Vectorworks and most CAD systems supporting DWG or DXF file formats.

Yes — the data is fully compatible with GIS platforms such as QGIS, ArcGIS, and MapInfo, supplied in SHP and GeoPackage formats.

Yes — CAD OS MasterMap integrates with BIM (Building Information Modelling) systems to provide accurate, georeferenced base mapping for architectural and engineering projects.

Common uses include planning applications, architectural design, engineering layouts, drainage and utility design, site surveys, asset management, flood analysis, and infrastructure planning.

Yes — fully editable vector layers integrate directly with your planning drawings, drainage layouts and utility plans.

Yes — OS MasterMap is survey-grade and meets all local authority accuracy requirements for professional submissions.

Yes — OS MasterMap Tiles (1 km × 1 km) are ideal for large-scale or regional analysis and planning projects.

The data is delivered in structured layers that you can turn on/off, restyle, or edit in your CAD or GIS software, giving you complete control over individual map features.

“Projection-ready” means the dataset includes the correct coordinate system information, ready to integrate into your project’s geospatial reference system — typically OSGB36 / British National Grid.

Professional OS data is vector-based, editable mapping for technical CAD/GIS work. Leisure maps are static raster images (PDF, JPG) intended for navigation or outdoor use.

Vector data (like OS MasterMap CAD) uses editable lines, points and polygons that can be modified or styled. Raster data (like MasterMap Tiles) consists of georeferenced image backdrops suitable for viewing but not direct editing.
