摘要：Thermal infrared sensors were commonly used for monitoring urban heat effects almost 15 years ago. Meanwhile the new multi- and hyper-spectral space-borne sensors offer this data too, therefore the airborne applications became rarely since the last 10 years. Common for all ThIR Sensors is a poor ground sampling distance. Newly developed small sensors are not adjusted to be used for Remote-sensing purposes. Beside this, their geometric resolution is still on a very poor level. In most cases, these sensors are designed for military application and not for absolute determinations. This means that calibration has to be done before such systems can be practically used. A new market was born to determine thermal losses of buildings, which is just a bigger scale than the urban heat applications were. New is the analysis of evaporation–heat effect due to water distribution in construction sites. This remotely sensed technology can be combined perfectly with humidity sensors like TDR and others. Power lines can be used as a humidity sensor as well which will be shown up in the last chapter
