Within the mainland of northern Europe active hydrothermal outputs are known only in the Polar Urals (East part of Bolshezemelskaya tundra). To study of the thermal ecosystem Pymvashor used satellite images obtained from satellites Terra (EOS AM-1) with a radiometer ASTER, summer aerial photographs from a helicopter Mi-8 and winter with an unmanned aerial vehicle, the data heat imagery portable computer thermograph «IRTIS-2000A», georadar scans with using georadar SIR-3000. As a result, made a layered GIS project natural boundary, including the relief and basic landscape facies, thermal panorama places the outputs of thermal springs, subsurface geological sections with the position of the level of thermal waters. Such an integrated use of satellite and subsatellite information allows you to create a full and reliable presentation about functioning of a unique ecosystem.
