Systematic land use inventory is seen as essential in order: • to produce proper land use statistics • to monitor the effects of imposed land use policies • to police land use policies and regulations • to perform scenario analyses • to perform integrated analyses © M. Stjernholm, P. N. Andersen, G. Groom, - DMU - 2000 • to follow changes and developments in land use over appropriate time periods

Background • GIS layers in Denmark were (1994) sparse and inconsistent • Land Use & Environmental Mapping in Denmark, mid-1990 s : - 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 © M. Stjernholm, P. N. Andersen, G. Groom, - DMU - 2000 – old – held by different organisations – lacking good land cover information

Objectives • a unitary polygon based land use map • selected supplementary databases – based on existing topographic mappings – nation-wide, scale 1: 25. 000 – 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 © M. Stjernholm, P. N. Andersen, G. Groom, - DMU - 2000 – for both research and administrative application

• 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) © M.

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 1 x 1 km areas (left) Such as, (right, shown in yellow) those P-3 heath areas with a certain mixture of grass and shrub heathland, bare areas and woodland © M. Stjernholm, P. N. Andersen, G. Groom, - DMU - 2000 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
