MONITORING OF SETTLEMENT AND OPEN SPACE DEVELOPMENT ON THE BASIS OF TOPOGRAPHIC SPATIAL DATA - CONCEPT, REALIZATION AND FIRST RESULTS

A concept and the first results of the Monitor of settlement and open space development are presented. The monitoring system will describe the state and the development of land use especially in regard to its sustainability for the entire Federal Republic of Germany. To this end, for the first time ever it makes use of topographical geobasis data (digital landscape model of the Authoritative Topographic-Cartographic Information System. These data allow for a more precise spatial and content-wise description of land use than that of the land register data, which serve as the basis for the official land use statistics. On the basis of the geobasis data an automatic calculation of indicators from the fields of settlement, open space, nature reserves, population and traffic occurs. The indicators are depicted in thematic maps, thus allowing for spatial and chronological comparisons. In addition to administrative spatial units (federal state, district, municipality), the indicator values are also presented in scales of various cell widths. For calculating building-based settlement indicators, the patented program SEMENTA© is used, which is based on an automated evaluation of analogue maps.
