Satellite data supports planning in municipalities
Climate change is making itself felt on the ground.
Local authorities are therefore increasingly looking at measures to adapt cities to the changes. Stefan Heiland from the City of Leipzig presented the joint research project ‘Urban Green Eye’ at the INTERGEO CONFERENCE. With the help of satellite data from the European COPERNICUS programme, comprehensive indicators are being developed and updated that are of crucial importance for the city's climate adaptation.
Four indicators are analysed: thermal load, for example through surface temperature, thermal relief, for example through the volume of greenery, hydrological relief through infiltration areas and sealing, and hydrological load, which is included in the assessment via the green volume deficit. As part of the project, significant increases and decreases in temperature were observed in the Leipzig urban area in connection with planting. The cooling effects of trees were also demonstrated.
The researchers used the satellite data to identify potential areas for replanting and to check the vitality of the urban greenery.
