In general, the thermography describes an imaging process by which the surface temperatures of objects are recorded.
The thermal imaging camera measures the infrared radiation emitted by a surface as a measure of the object's temperature and converts it into electrical signals. These electronic signals can then be visualised using various evaluation methods.
Nowadays, thermographic systems are widely used in construction technology, medicine, research, industrial production and many other areas of daily life. Especially in the context of advancing global warming, thermography is becoming increasingly important. With advancing climate change, the probability of longer hot days and periods is increasing. In this context, the urban environment heats up more strongly. Especially in large urban centres, so-called heat islands can form in the summer months. With the help of large-scale thermal scanner flights, such heat hot spots can be identified. The knowledge gained from this provides a basis for planning further climate change adaptation strategies.
