What data is expected?

Geographic information is instrumental for many use cases, including the mapping of unemployment statistics or demographics, as well as journey planning. See our methodology section for more information.

  • Scale of 1:250,000 (1 cm = 2.5km)

Question Answer Comment
Openly licenced Yes
In an open and machine-readable format DBF, GML, SHP, SHX Also GeoTIFF, TIFF-LZW ASCII Grid, MapInfo TAB, DBX and NTF for some parts or versions of this data.
Downloadable at once Yes The user may need to download more than one data product to cover all of the criteria, but they are available from a single source and can be selected for download in a single operation.
Up-to-date Yes
Publicly available Yes This is debatable and not easy to answer as Yes/No. Users do not need to register or give their name but must provide an email address. Ordnance Survey then provides a download link by email (usually immediately). So technically users have to request the data but the process is automated and reasonably frictionless.
Available free of charge Yes
findable 4
findable_steps No steps as I am a user of the data and have been aware of the location since the data products were launched in 2010. However the data is discoverable via Google using search terms such as: national map open data

Collected by government Yes
usability 3 OS is the authoritative source for this type of data in Britain, so the data is high quality and as usable as I would reasonably expect. This is GIS data so there there are some intrinsic knowledge requirements, of course.
