1 LaSyS – workshop Tune 2005 Spatial Indicators for Landscape Development in Denmark - GIS-based Analysis of Long Term Changes and Persistence Bernd Münier, Pia Frederiksen, Gregor Levin National Environmental Research Institute - Denmark Department of Policy Analysis

2 Spatial indicators for landscape development in Denmark Bernd Münier...LaSyS - Tune 2005 Why spatial indicators ? Landscape composition (a-spatial): –OK for human utilization (census, agricultural production,...) –not satisfying for ecological applications and biodiversity issues. Lack of information on: –configuration –persistence –=> need analysis of spatial and temporal landscape development CB 2010 requires spatial indicators !

5 Spatial indicators for landscape development in Denmark Bernd Münier...LaSyS - Tune 2005 Mapping local changes – 3 lake areas on Topographic map => Common boundaries

6 Spatial indicators for landscape development in Denmark Bernd Münier...LaSyS - Tune 2005 Dallerup sø study area 10 km

7 Spatial indicators for landscape development in Denmark Bernd Münier...LaSyS - Tune 2005 St. Gribsø study area 10 km

8 Spatial indicators for landscape development in Denmark Bernd Münier...LaSyS - Tune 2005 Kragsø study area 10 km

11 Spatial indicators for landscape development in Denmark Bernd Münier...LaSyS - Tune 2005 Landscape spacio-temporal dynamics

12 Spatial indicators for landscape development in Denmark Bernd Münier...LaSyS - Tune 2005 Compare to development by chance – persistence is: –Lowest: every trace of land may change to every land cover type = max entropy –Highest: persistence = MIN(T1,T2) Period I: Meadows [ha] Observed persistence633 Persistence by chance59 Maximum persistence975 Temporal development – how persistent is land cover? Persistent areas. Hi-Lo bars indicate maximum persistence (Hi) and persistence by chance (Lo)

13 Spatial indicators for landscape development in Denmark Bernd Münier...LaSyS - Tune 2005 Grain size: The spatial dimension of temporal changes

14 Spatial indicators for landscape development in Denmark Bernd Münier...LaSyS - Tune 2005 Conclusions The ‘long’ perspective spans only about 120 years. Topographic maps contribute with extra spatial information –but some important information is missing time gaps of ~ 40 years dry grasslands not mapped –=> additional information from remote sensing Indicators expressing landscape configuration, persistence and changes. Spatial and temporal dynamics. Outlook : integration with physio-geographical data, agricultural census, EU subsidies, protected areas (Natura 2000,...), environmental monitoring data etc.
