Спутник ДЗЗ. LandSat 7. [Редактировать]

Аппарат запущенн в рамках программы Landsat. Является проектом трех крупных американских правительственных организаций: NASA, NOAA и USGS. Он снабжен аппаратурой ETM+ (Enhanced Thematic Mapper Plus — усовершенствованный тематический картограф), которая обеспечивает съемку земной поверхности в четырех режимах: VNIR (Visible and Near Infrared — мультиспектральный видимый и ближний инфракрасный диапазон), SWIR (Shortwave Infrared — средний инфракрасный диапазон), PAN (panchromatic — панхроматический диапазон), TIR (thermal infrared — тепловой инфракрасный диапазон).
