| 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 | |
| licence_url | https://www.ordnancesurvey.co.uk/opendata/licensing.htm | The data is re-usable under the Open Government Licence, which is compliant with the Open Definition. |
| 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. |
| collector_name | Ordnance Survey | This submission applies only to Great Britain i.e. excluding Northern Ireland. |
| characteristics | Scale of 1:250,000 (1 cm = 2.5km), Markings of national traffic routes, Markings of relief/heights, Markings of water stretches, National borders | |
| location | https://www.ordnancesurvey.co.uk/opendatadownload/produ - OS OpenData | Data is available as a suite of produces that collectively meet the criteria. |
ok!
