FAQs
General Questions
What is OS Professional Data? OS Professional Data consists of survey-grade Ordnance Survey MasterMap products delivered in editable CAD formats (DWG, DXF, SHP, GeoPackage) designed for architects, engineers, planners, and GIS professionals who need accurate, layered base mapping.
What formats are OS Professional Data products available in? Professional data is available in DWG, DXF, SHP (Shapefile), and GeoPackage formats - all projection-ready and compatible with CAD and GIS software.
What does "site-centred" mean? Site-centred extracts are tailored to your exact area of interest, ensuring the location you need is at the center of your data extract rather than at an edge or awkward position.
How quickly can I receive my data? Data is delivered by email with fast turnaround times, available 7 days a week.
How long has ukmapcentre.com been an OS Partner? Ukmapcentre.com has been a trusted Ordnance Survey Partner for over 20 years, providing professional mapping data.
Choosing the Right Product
What's the difference between CAD OS MasterMap and VectorMap Local? CAD OS MasterMap is the most detailed editable vector data from OS, showing individual buildings, boundaries, and features - perfect for detailed design work. VectorMap Local (1:10,000) is a cleaner, more generalized backdrop ideal for context maps and base plans but not as detailed as MasterMap.
Which product should I use for architectural or engineering design? CAD OS MasterMap in DWG/DXF format is the best choice - it provides fully editable, layered vector data at the highest detail level, perfect for integration with planning drawings and BIM workflows.
What are OS MasterMap Tiles used for? OS MasterMap Tiles are true-orthorectified raster tiles (1 km × 1 km) ideal for mapping backdrops, large-area planning projects, and GIS overlays.
What is OS Height Data (DTM) and when do I need it? OS Height Data is a Digital Terrain Model that provides elevation information. It's essential for contouring, visibility analysis, flood modeling, drainage planning, and 3D terrain modeling in CAD and GIS.
Which product is best for context maps? VectorMap Local (1:10,000) is ideal for context maps, asset registers, and base plans where you need clear, generalized mapping rather than fine detail.
Software Compatibility
What CAD software is compatible with these products? OS Professional Data works with AutoCAD, MicroStation, and other CAD packages that support DWG and DXF formats.
Can I use this data in GIS software? Yes, the data is compatible with GIS workflows and is available in formats like SHP (Shapefile) and GeoPackage in addition to CAD formats.
Is the data compatible with BIM workflows? Yes, CAD OS MasterMap can be integrated into BIM (Building Information Modeling) workflows, providing accurate base mapping for architectural and engineering projects.
Usage & Applications
What can I use OS Professional Data for? Common uses include planning applications, architectural design, engineering layouts, drainage and utility design, site surveys, asset management, context maps, flood analysis, and infrastructure planning.
Can I overlay this data with my own designs? Yes, the fully editable vector layers are designed to integrate seamlessly with your planning drawings, drainage layouts, utility plans, and other design work.
Is the data accurate enough for planning applications? Yes, OS MasterMap data is survey-grade and provides the precision required for planning applications and professional design work.
Can I use this data for large-area projects? Yes, OS MasterMap Tiles are specifically designed for large-area planning and analysis, delivered in convenient 1 km × 1 km sections.
Technical Questions
What does "fully editable vector layers" mean? The data comes as organized layers that you can edit, modify, hide, or style in your CAD or GIS software - giving you complete control over the mapping elements.
What does "projection-ready" mean? The data is delivered in coordinate systems that can be easily integrated into your existing project coordinate reference systems (projections).
How is this different from leisure maps? Professional data is editable vector data designed for technical work in CAD/GIS, while leisure maps are raster images (PDF, JPG) designed for navigation and outdoor activities.
What is the difference between vector and raster data? Vector data (like CAD OS MasterMap) consists of editable lines, points, and polygons that can be modified. Raster data (like MasterMap Tiles) consists of georeferenced images suitable for backgrounds and visualization but not editing.
