Спутник ДЗЗ. QuickBird-2. [Редактировать]

Спутник был выведен на околоземную солнечно-синхронную орбиту высотой 450 км, обеспечивающую его прохождение над любым районом Земли каждые 1–5 дней (в зависимости от широты). Основными преимуществами спутника QuickBird являются широкая полоса охвата (размер сцены — 16,5х16,5 км), высокая метрическая точность, возможность заказа полигонов сложной формы, в том числе, протяженных объектов шириной 5 км. Расчетный срок пребывания на орбите составляет около 7 лет.

Области применения данных дистанционного зондирования, полученных со спутника QuickBird:

  • Создание и обновление топографических и специальных карт и планов вплоть до масштаба 1:2 000. 
  • Инвентаризация и контроль строительства объектов инфраструктуры транспортировки и добычи нефти и газа. 
  • Выполнение лесоустроительных работ, инвентаризация и оценка состояния лесов. 
  • Инвентаризация сельскохозяйственных угодий, создание планов землепользования, точное земледелие. 
  • Обновление топографической подосновы для разработки проектов генеральных планов перспективного развития городов, схем территориального планирования муниципальных районов. 
  • Инвентаризация и мониторинг состояния транспортных, энергетических, информационных коммуникаций. 
  • Широкий круг задач в области охраны окружающей среды.
