Stock Photo - 07 July 2023, Saxony, Chemnitz: The controller of a special drone shows the thermal image of the area around the city hall in Chemnitz. Scientists from the Thuringia Institute for Climate Protection and Sustainability fly the drone over parts of the center. The city of Chemnitz wants to better prepare itself for future hot spells. To this end, heat focal points are now being identified in the city center. The drone, equipped with a thermal camera, provides detailed thermal images during the day and after sunset. The aim is to create important data for the city's heat action plan. The aim is to identify areas that are particularly at risk and to determine how high the overall heat load is during the summer half-year in individual parts of the city.
