Meridian™2	Medium scale (1:50,000 nominal) regional/district data with road network, railways, built up areas (including individual streets), water features, county, district, unitary authority boundaries, railway stations. This is more detailed than Strategi® data.	Available in NTF, DXF, SHP and MIF / MID formats.
1:10,000 Scale Raster	High-resolution scanned image of 1:10,000 scale mapping. Detail includes fences, field boundaries, road names and buildings.	Available in compressed TIFF.
1:25,000 Scale Colour Raster	High resolution scanned images of Explorer® mapping providing national coverage of Great Britain. Includes rights of way information for England and Wales, hill contours, height information and field boundaries.	Available in compressed TIFF.
1:50,000 Scale Colour Raster	The definitive raster dataset providing national coverage for Great Britain. This dataset mirrors the popular paper OS Landranger® series.	Available in compressed TIFF.
1:250,000 Scale Colour Raster	A road atlas style raster dataset providing national coverage for Great Britain.	Available in compressed TIFF.
MiniScale®	A 1:1million scale raster product providing national coverage for Great Britain.	Available in compressed TIFF.
Land-Form PANORAMA™	Contours and digital terrain model (DTM) data derived from the Landranger® 1:50,000 scale maps. Note: this data is no longer supported by Ordnance Survey and will not be updated after 31 August 2004. It is available in two different forms: Contours (10m vertical interval) plus lakes and coastline. The contours have 3m height accuracy. Digital Terrain Model (DTM) (50m horizontal grid interval, 1m height resolution). The DTM has a 5m height accuracy.	Available in NTF and DXF formats.
Land-Form PROFILE™	Contours and digital terrain model (DTM) data at 1:10,000 scale. Land-Form PROFILE™ is a height dataset provides detailed height data defining the physical shape of the landscape of Great Britain. It is available in two different forms: Contours (5m vertical interval; 10m vertical interval in mountain and moorland areas). The 5m vertical interval contours have +/- 1 m height accuracy. The 10m vertical interval contours have +/- 1.8m height accuracy. Digital Terrain Model (DTM) (10m horizontal grid interval, 1m height resolution). The DTM has a 2.5m or 5m height accuracy. Accuracy is less in mountain and moorland areas.	Available in NTF format.
Strategi®	Small scale (1:250,000) regional data with roads, railways, water features, woodland, settlements, county and district boundaries. The paper equivalents are "OS Travel Map – Road" and OS road atlases.	Available in NTF, DXF, SHP and MIF / MID formats.
1:50,000 Scale Gazetteer	All settlement place names, hills, farms, woodland and natural features found on the 1:50,000 Landranger® paper map series, plus associated counties and 1km National Grid references.	Available in CSV and TXT formats.
Code-Point® with polygons	National Grid co-ordinates for a point within each postcode unit in Great Britain, and the digital postcode unit boundaries for use in a GIS.	Codepoint available in NTF and CSV formats, polygons available in SHP or MIF / MID formats.
Boundary-Line™	Boundary-Line is the key dataset of administrative and voting boundaries in Great Britain.	Available in NTF, SHP and MIF / MID formats.

Land-Line.Plus® (withdrawn in August 2008)	Definitive large-scale dataset till MasterMap replaced it, surveyed to a high degree of accuracy at three source scales: 1:1,250 (urban areas), 1:2,500 (small urban areas and rural areas), 1:10,000 (upland, mountain and moorland areas). Showed individual buildings, walls and fences, plus vegetation, land form and administrative information. Was used to make Superplan plots. Only small amounts of England were covered by Moorland Land-Line.Plus: parts of each of Dartmoor, the Peak District, Lake District, Forest of Bowland, North Pennines, North Yorkshire Moors. In Wales, Moorland Land-Line.Plus covered much of Snowdonia, the Brecon Beacons and the spine of hills running between them. In Scotland, much more was covered by Moorland Land-Line.Plus including much of the Highlands and Islands, Shetland (but not much of Orkney) and the major blocks of lowland hills.	All digital holdings of Land-Line.Plus data should now have been deleted.

Other Ordnance Survey products may be added in future years, although this is entirely at the discretion of JISC and Ordnance Survey. However, Digimap is a delivery mechanism to which many other datasets can be added. If there are particular datasets you would like to see available through Digimap, please contact EDINA (edina@ed.ac.uk). More information about the currency of the data and Ordnance Survey's policy on updating the data and distributing updates to Digimap can be found on this page: Revision and Update of Ordnance Survey products.

NTF and GML data formats may need to be converted before they can be used in GIS or CAD software. A list of companies who supply conversion software is provided within the service. URLs from which free converters can be downloaded are also provided. If you don't yet know about using downloaded data in GIS or other software then ask about it in your institution. They may already support and hold licences for GIS software. You should investigate this first. There are also Eduserv Chest software deals which can provide you with some GIS packages more cheaply than if you approach the seller directly. EDINA provides support in the use of Ordnance Survey data for key GIS software in use by the HE community, but does not recommend any particular software packages. You can find details of your Digimap Site Representative on the EDINA web site. They will be able to put you in touch with your institution's experts.

IMPORTANT: Each user must read the Terms of Use for the Digimap service when they register. These, and the Frequently Asked Questions on the Sub-Licence Agreement are available on the EDINA web site, and can be viewed from within the service. These specify what you can and cannot do with the data. If you are in any doubt as to the terms of use for Digimap, please do not hesitate to contact EDINA with your query.
