Thermographic survey of urban areas to identify overheating zones
GeoFly GmbH uses airborne thermography to map and analyze large areas in urban environments. A key objective is to visualize urban heat islands and cold air corridors and incorporate this information into urban planning decision-making processes. With increasingly intense heat waves, this is a crucial tool for cities' climate adaptation strategies.
The most well-known phenomena of urban climate are urban heat islands, characterized by large temperature differences within built-up areas and their surrounding areas. Urban growth leads to changes in wind patterns, air quality, and ventilation. In conjunction with meteorological and air quality measurements, aerial thermographic surveys, due to their comprehensive representation of surface radiation temperatures, provide the most important basis for understanding the current climatic situation. Aerial surveys of urban climate should include at least two different recording times (e.g., evening and morning). This results in classified thermal maps of surface temperature behavior, which demonstrate a close relationship between areas of warming and cold air within the urban microclimate.
