New remote sensing systems and GIS-techniques for the monitoring of urban ecological processes

The climate of urban areas is a very sensitive topic in the content of human health a sustainable urban development. There is often a difference between the high demands of urban planning and the reality. Two aspects regarding urban climate are discussed in this paper. First we present a method for the automated analysis of vegetated areas and especially vegetated roofs in the inner city using multispectral and extremely high resolution imagery. The second part of this paper focuses on a potential cooling area near the city and especially the change of this area after its construction. A qualitative estimation and visualization of the impact regarding climatic effects is performed using stereoscopic heights data acquired by a digital scanner.
