Спутник ДЗЗ. WorldView-2. [Редактировать]

Коммерческий спутник, предназначенный для наблюдения Земли. Принадлежит компании DigitalGlobe. Спутник WorldView-2 создавался без привлечения средств федерального бюджета на собственные деньги компании DigitalGlobe и коммерческих инвесторов. WorldView-2 является первым коммерческим аппаратом с восьмиканальным спектрометром, который включает традиционные спектральные каналы: красный, зеленый, синий и ближний инфракрасный-1 (NIR-1), а также четыре дополнительных канала: фиолетовый (coastal), желтый, «крайний красный» (rede edge), ближний инфракрасный-2 (NIR-2). Спектральные каналы спутника WorldView-2 могут обеспечить более высокую точность при детальном анализе состояния растительности, береговой линии и прибрежной акватории. Данные, получаемые с этого спутника, имеют точность геопривязки не менее 4 м СКО без применения наземных точек привязки.

Характеристика спектральных каналов WorldView-2

Фиолетовый (или прибрежный — Coastal; 400–450 нм)

  • поглощается хлорофиллом в здоровых растениях и способствует проведению вегетационного анализа;
  • значительно подвержен атмосферному рассеянию, требует совершенствования методов атмосферной коррекции;
  • меньше остальных поглощается водой и полезен при глубоководных исследованиях.

Синий (Blue; 450–510 нм)

  • быстро поглощается хлорофиллом в растениях;
  • хорошо проникает сквозь водную поверхность;
  • наименее подвержен атмосферному рассеянию, поглощение сопоставимо с фиолетовым каналом.

Зеленый (Green; 510–580 нм)

  • более узкий по сравнению с зеленым каналом на спутнике QuickBird;
  • может более точно фокусировать отражательную способность растений;
  • идеально подходит для расчета жизнеспособности растений;
  • эффективен для распознавания видов растений в сочетании с желтым каналом.

Желтый (Yellow; 585–625 нм)

  • очень важен для классификации объектов;
  • обнаруживает «желтизну» конкретных растений на земле и в воде.

Красный (Red; 630–690 нм)

  • уже красного канала на спутнике QuickBird со смещением в диапазон более длинных волн;
  • лучше фокусируется на поглощении красного цвета хлорофиллом в здоровых растениях;
  • один из важнейших диапазонов для выделения растений эффективен для классификации грунтов без растительности, дорог и геологических объектов.

Крайний красный (Red-Edge; 705–745 нм)

  • базируется на высокой отражательной способности растений;
  • эффективен для определения здоровья растений и классификации растительности.

Ближний инфракрасный-1 (NIR1; 770–895 нм)

  • более узкий по сравнению с аналогичным каналом на спутнике QuickBird для более четкого отделения его от крайнего красного канала;
  • наиболее эффективен для определения содержания влаги и растительной биомассы;
  • эффективно отделяет водоемы от растительно- сти, обеспечивает разделение видов растений и грунтов.

Ближний инфракрасный-2 (NIR2; 860–1040 нм)

  • накладывается на канал ближний инфракрасный-1, но менее подвержен атмосферному влиянию;
  • обеспечивает проведение более глубокого анализа растительности и исследования биомассы.   

Некоторые космические снимки WorldView-2 могут использоваться в интернет-сервисах Google Планета Земля и Карты Google. Высокое пространственное разрешение и широкий спектральный диапазон позволяют решать задачи картографии, мониторинг изменений земной поверхности, широкий круг задач охраны окружающей среды. Наличие дополнительных спектральных каналов расширяют возможности анализа изображений, в частности увеличивают диапазон типов распознаваемых объектов (разные виды растительности или подводные живые микроорганизмы); расширяют число оцениваемых параметров и позволяют различать инородные объекты; улучшают качество цветопередачи, приближая его к естественному восприятию человека.

22016-07-20. ВВС США сообщили о возможном столкновении космического аппарата WorldView-2 с космическим мусором.
ВВС США сообщили о том, что космический аппарат WorldView-2 участвовал в столкновении с космическим мусором 19 июля 2016 года. В настоящее время специалисты компании DigitalGlobe проводят анализ инцидента, однако они склоняются к мнению о том, ничего критичного не произошло и аппарат работает штатно.Тэги: WorldView-2Военно-воздушные силы СШАDigitalGlobe
