Спутник ДЗЗ. Rocsat 2. [Редактировать]

Аппарат предназначен для получения цифровых изображений земной поверхности в панхроматическом и мультиспектральном режимах. Спутник ведет съемку двумя камерами. Его отличает маневренность, возможность ежедневной съемки, а также более раннее прохождение над любой точкой Земли (9 ч 30 мин. утра по местному времени, тогда как у большинства спутников – 10 ч 30 мин.), что увеличивает вероятность безоблачной съемки.

Решаемые задачи:

  • создание и обновление топографических и специальных карт вплоть до масштаба 1:25 000;
  • текущий контроль строительства объектов инфраструктуры транспортировки и добычи нефти и газа и оперативный мониторинг их состояния;
  • постоянный мониторинг экологического состояния территорий в районах добычи, переработки, транспортировки нефти и газа, других полезных ископаемых; обновление топографической подосновы для разработки проектов схем территориального планирования муниципальных районов и субъектов федерации; инвентаризация лесов, выполнение лесоустроительных работ.;
  • текущий контроль лесопользования и оперативный мониторинг состояния лесов; мониторинг состояния посевов, оценка засоренности, выявление вредителей и болезней сельскохозяйственных культур, прогнозирование урожайности;
  • текущий мониторинг развития эрозионных, карстовых процессов, заболачивания и опустынивания, засоления, лесных и степных пожаров, половодий, паводков и т. п.; мониторинг природных и антропогенно-спровоцированных катастроф.
