Abstract

Space-based thermal vision is widely used to solve problems of ecological safety: the measurement of the surface temperature of water and dry land, the determination of the components of the thermal balance of terrestrial ecosystems, and the thermophysical properties of ecosystems (evaporation rate and thermal inertia). Ecological risk zones and sections of thermal contamination and high anthropogenic loading on the ecosystem have been mapped. Satellite thermal-vision systems are considered, and their technical characteristics are compared. Data-processing methods for purposes of ecological safety are analyzed. Examples are given of the use of the results of space-based thermal imaging for nature conservation and ecological safety. The role of space-based thermal vision in studying new threats to ecological safety is determined.
