What´s Next: Remote Sensing Green Roof Inventory and Potential Analysis

Kurzfassung

Green Roofs can help to adapt cities for climate change, through the provision of cooler microclimates and reduced stormwater run-off. In order to evaluate these positive effects in a quantitative way, information about the already existing Green Roofs and potential Green Roof sites is needed. In a current research project the German Aerospace Center (DLR), the German Roof Gardener Association (DDV) and different German partner cities are developing a methodology with which already existing Green Roofs and potential roof areas can be identified and inventoried from a "birdseye view". High-definition aerial photos and digital real estate registers provide information on the size of the spaces. This data can make a valuable contribution to the spread of Green Roofs in Germany and abroad. The project is funded by the German Federal Environmental Foundation (DBU).
