Project Model Generalisation Basis-DLM Model generalisation is the automated derivation of another DLM of a lower structuring degree and granularity than the base model. (data reduction) DLM50.1 DLM100.1 Generalisation processes: Semantic generalisation Geometric generalisation - Classification - Combination - Aggregation - Change of the geometry type - Geometric simplification
Project Model Generalisation Model Generalisation Results - Rule-based process (Objektartenkatalog OKBasisDLM - OK50 OK100) - 100% fully automated process - Processing whole BW in one MG process - Producing of a consistant and homogenious data set - 35% reduction of the data volume (currently) - Total processing runtime of whole BW data is 10 days (e.g. DLM50.1)
Project Cartographic Generalisation Cartographic generalisation is the processing of a topologically correct and visually correct data set (on basis of style sheet catalogues). Basis-DLM DLM50.1 DLM50.2 DLM100.1 DLM100.2
Project cartographic generalisation Generalisation processes: The Cartographic generalisation process is solving all kinds of graphical conflicts (as e.g. Typification, Simplification, Merging Enlargement ). The Workflow is scale independent. It is controled by parameters of the style sheet catalogues (e.g. minimum size, minimum distance, movebility). This part is scale dependent! Results: - Rules-bases process (SK50 and SK100) - Managing of all generalization conflikts in one single workflow - Identical and editor indepedent generalisation results - Total processing runtime of whole BW data in 8 weeks
Project Representation Representation Component: - Automatic representation according style sheet catalog (SK) - Possibility of interactive editing of still open conflicts - Addition of Contour Lines (derived from the DGM) - Label placement and Grid Basis-DLM DLM50.1 DLM50.2 DTK 50 DLM100.1 DLM100.2 DTK 100
