Digimap is an online mapping and data delivery service that offers a number of data collections, including Ordnance Survey,
historical, geological, LiDAR and marine maps and spatial data.
What You Can Access
The Library has access to the following areas in Digimap:
Ordnance Survey: OS maps covering the whole of Great Britain and at scales ranging from 1:1250 up to 1:750000.
Historic: historical OS maps of Great Britain, the originals of which were published between 1846 and 1996.
Geology: geological map data from the British Geological Survey (BGS).
Marine: raster nautical charts and Marine Themes vector data from the UK Hydrographic Office.
Environment: Land Cover data from the Centre for Ecology and Hydrology.
Separate datasets are available for 1990, 2000, 2007 and 2015. Also included are Dudley Stamp’s maps of the 1930’s Land Utilisation Survey of Britain.
Aerial: high quality aerial photography of Great Britain.
Lidar: lidar data derived from the Environment Agency, showing Digital Terrain Models (DTM) of the bare earth
surface and Digital Surface Models (DSM) that show the vegetation canopy.
You can use Digimap to zoom in on your area of interest, print maps in A4 to A0 size, annotate maps, download maps in PDF, PNG or JPG
files and download the data for use in GIS and CAD software.
