Abstract

Using images in the thermal infrared range, to obtain cartographic models of the urban areas to identify stable thermal anomalies, areas of thermal structures related anthropogenic geosystems urbanized areas of the steppe zone, on the basis of the identified areas of the city, varying in levels of surface heat island. When calculating the anomalous areas allocated classes with maximum temperatures for different times and images defined areas component of the intersection, coincident in quantitative terms. The article presents the results of a comprehensive monitoring of vegetation in urban landscapes according to different times of multispectral imaging medium spatial resolution for detection of the intensity of thermal radiation on the degree of activity of the growing urban vegetation. A general geoecological situation in the cities of Dallas and Magnitogorsk and presented cartographic models of thermal structures and anomalies comprehensive assessment of the state of “green zones” and their impact on the urban landscape microclimate.

Keywords

thermal radiation intensity, vegetation index, technogenic landscape, thermal pollution, comfortable environment.
