摘要: ABSTRACTOpenStreetMap (OSM) database has previously been used to support spatial disaggregation of population data by partly masking out non-residential impervious areas in the European Copernicus imperviousness layer (IL). However, exact procedure OSM incorporation is unknown, and its contribution improvement estimation accuracy never studied. In this article, we present a sensitivity study find which road categories should be for IL how linear features might transformed raster representation. Using Austria Slovenia as area, 2006 commune counts are disaggregated into 100 m grid cells using 12 versions modified IL. Further tuning estimates performed CORINE Land Cover (CLC) an iterative algorithm. Disaggregated grids then validated against reference 1 km census-based data. The results show that overall error was reduced thanks all tested scenarios, although relat...
