We now have two more collections available via Digimap:
Marine Digimap
Marine Digimap offers two types of data.Firstly, raster nautical charts are derived from UK Hydrographic Office paper charts and chart panels. This chart dataset comes in two versions: Raster Charts and Raster Charts XL, which excludes land-based features so you can add your own.
Secondly, Marine Themes vector data covers all UK waters and is a feature rich dataset derived from authoritative material obtained from the UK Hydrographic Offices, as well as comprehensive source data where available. Marine Themes Vector is engineered into logical data layers for easy loading and efficient use in Geographic Information Systems (GIS). Data attributes have been designed with analysis and querying in mind.
All data is licensed by OceanWise.
Marine data is extensively used in offshore engineering projects, management of marine and coastal environments, marine ecology studies, environmental impact assessments and tourism.
Environment Digimap
Environment Digimap brings easy access to Land Cover data from the Centre for Ecology and Hydrology. Separate datasets are available for 1990, 2000, 2007 and 2015, all national coverages. Also included are Dudley Stamp’s maps of the 1930’s Land Utilisation Survey of Britain.Make a map of your chosen area of interest using Environment Roam, which also enables the data at any location to be queried, printed and compared side by side with the same data of a different date. Use Environment Download to search and retrieve the data for your area of interest.
The Land Cover data can be used to plan, manage or monitor agriculture, ecology, conservation, forestry, environmental assessment, water supplies, urban spread, transport, telecommunications, recreation and mineral extraction. It is particularly useful when combined with other datasets. Use the land cover data to examine the coincidence of a given species with particular land cover types, make assessments of habitats at risk from a specific development, or look at national distributions of land cover types and how it is affected by other environmental and human factors.
Current examples of the application of the Land Cover Map include detection of changing land cover, landscape management, mapping bracken in the context of health studies (bracken supports ticks carrying human disease), environmental assessments of motorway extensions, and planning of telecommunication lines.
