  1. AIS Land Cover Map of Denmark Examples of its application 1. for the AIS Land Use map of Denmark 2. for habitat / vegetation type application

  2. Systematic land use inventory is seen as essential in order: • to produce proper land use statistics • to follow changes and developments in • land use over appropriate time periods • to monitor the effects of imposed land use policies • to police land use policies and regulations • to perform scenario analyses • to perform integrated analyses

  3. 1. for the AIS Land Use map of Denmark

  4. Background • GIS layers in Denmark were (1994) sparse and inconsistent • old • held by different organisations • lacking good land cover information • Land Use & Environmental Mapping in Denmark, • mid-1990s : • - an abundance of mappings produced and used by the various • organisations • - no common map base or data structure • - a major impediment to inter-disciplinary monitoring and modelling

  5. Objectives • a unitary polygon based land use map • selected supplementary databases • based on existing topographic mappings • nation-wide, scale 1:25.000 • for both research and administrative application • supplemented by other relevant data ... including a satellite image derived Land Cover Classification • as a Collaboration across the research institutes and policy agencies of the Ministry of Environment & Energy and related Governmental departments

  6. Participants • National Environmental Research Institute • Dept. Lake and Estuarine Ecology • Dept. Landscape Ecology • Dept. Policy Analysis • Dept Marine Ecology • Geological Survey of Denmark and Greenland • Danish Forest and Landscape Research Institute • National Forest and Nature Agency • Danish Energy Agency • Danish Environmental Protection Agency • Spatial Planning Dept. • Kort & Matrikelstyrelsen • Danish Institute of Agricultural Sciences • The Danish Counties • Royal Danish Administration of Navigation and Hydrography

  7. Overview of databases • Basemaps: • Land use map • Coast lines • Streams • Satelite data archieve • Satelite classification • Vegetation data • Protected nature types • Forests • Terestrial nature types • Administrative zones • Planning regions: • Urban areas • Village boundaries • Rural planning • Summer houses • Wind energy • Drinking water interest • Waste deposits • Mineral extraction sites • Leisure centres/hotels • Camping/Youth hostels • EU-bird protection site • Ramsar-sites • EU-habitat site • Wildlife sanctuaries • Cultural protections • Urban areas • Land use • Hydrological data • Lakes • Stream sections • Catchments • Gauging stations • Wetlands • Geology • Surface Geology 1:25.000 • Surface Geology 1:200.000 • Marine areas • Bottom sediments • Depth model • Restrictions in distribution

  8. Example - Land use map • Based on data fusion from: • Topographical data in scanned and digital form • Map(s) of protected nature types • Digital map of arable fields • Classification of satellite data • Sequential integration of the different layers, applying layer dependent rules for handling cartographic and thematic issues • CORINE LC based coding and nomenclature as far as possible (4 digits)

  9. + Protected nature types + Agricultural fields + Land cover + Generalisation Final map Topographic map

  21. Arealfordeling i net celler

  22. e.g. … for targeting protected nature area field survey work For a large area of heath in the SW of Viborg county, the Paragraph-3 heath areas can be sub-divided into a set of 1x1 km areas (left) The AIS LCM data (centre) for the P-3 areas within each grid cell can then be interrogated for a particular land cover composition pattern Such as, (right, shown in yellow) those P-3 heath areas with a certain mixture of grass and shrub heathland, bare areas and woodland
