Abstract

GIS-based Strategic Environmental Assessments (SEA) generally require the processing of a variety of environmental and planning data. Therefore, it is necessary to combine thematic datasets in different spatial resolutions. This chapter presents a method for the generalization of a city-wide biotope-type assessment and an urban structure and inventory of open and green spaces map for the city of Berlin. The method includes the aggregation of an ecological assessment of a biotope-type map to a more generalized block-based inventory of open and green spaces map by areal weighting. The results show that the combination of the two datasets can be very sufficiently utilized to detect areas of high ecological significance in early stages of environmental planning. The application of a 1 ha minimum mapping unit leads to a better integration of biotope-type information into the block structure than the utilization of a 3 ha-size criterion.
