FAQs

Can I use these in commercial projects?

Everything is built from open datasets under permissive licences, so yes.

What format are the files in?

DWG format, compatible with AutoCAD and other CAD tools. Aligned to OS grid and set BYLAYER.

What is the difference between the Overview Basemap and OS MasterMap?

Our Basemap is created from open data sources, including OpenStreetMap, various OS OpenData products, and HM Land Registry boundaries. These data sets are combined to produce our own map drawings.
OS MasterMap, on the other hand, is Ordnance Survey’s most detailed and proprietary mapping product. It is only available through their Licensed Partners.
