Die Erfassung von städtischen Oberflächen mittels EDV-gestützter Luftbildauswertung : ein Beitrag zur klimatologischen und luftklimatischen Bewertung von städtischen Teilflächen

Abstract. The article shows that the computer-aided, analogous-visual, stereometric interpretation of large-scale colour-infrared (CIR) aerial photographs and subsequent data processing in a Geographical Information System (GIS) can provide fundamental data necessary to describe aspects of urban ecology in a scale relevant for city-planning. This is exemplified by an evaluation of urban areas concerning their climates and airpollution using maps of urban surfaces (scale1:2500). An argumentation relying on such detailed and current basic data can stress the importance of environmental aspects in contrast to competing public and private interests in the process of city planning.
