黑河生态水文遥感试验：WorldView遥感数据集

WorldView卫星是Digitalglobe公司的下一代商业成像卫星系统。它由两颗（WorldView-I和WorldView-II）卫星组成（WorldView-III预计将于2014年发射），其中WorldView-I已于2007年发射，WorldView-II也在2009年10月份发射升空。发射后在很长一段时间内被认为是全球分辨率最高、响应最敏捷的商业成像卫星。该卫星将运行在高度450 km、倾角98°、周期93.4 min的太阳同步轨道上，平均重访周期为1.7天，星载大容量全色成像系统每天能够拍摄多达50万 km2的0.5 m分辨率图像。卫星还将具备现代化的地理定位精度能力和极佳的响应能力，能够快速瞄准要拍摄的目标和有效地进行同轨立体成像。
2012年共获取WorldView影像1景。覆盖范围为排露沟流域，获取时间（北京时间）为：2012-05-12。
获取的数据为全色模式（PAN），分辨率0.5 m，产品级别为L2正射影像。

The WorldView satellite system is the next-generation commercial Earth imaging satellite system developed by DigitalGlobe. It consists of two satellites: WorldView-I and WorldView-II (WorldView-III was scheduled for launch in 2014). Specifically, WorldView-I was launched in 2007, and WorldView-II was launched in October 2009. For a long period after their launches, they were recognized as the commercial imaging satellites with the highest spatial resolution and most agile response capabilities worldwide. These satellites operate in a Sun-synchronous orbit at an altitude of 450 km, with an inclination of 98° and an orbital period of 93.4 minutes, boasting an average revisit time of 1.7 days. The on-board high-capacity panchromatic imaging system can capture up to 500,000 km² of 0.5 m resolution imagery per day. Additionally, the satellites are equipped with advanced geolocation accuracy and excellent operational responsiveness, enabling rapid target targeting and effective along-track stereoscopic imaging.

In 2012, a total of one WorldView imagery scene was acquired. The coverage area is the Pailugou Watershed, and the acquisition time (Beijing Time) was 2012-05-12.

The acquired data is in panchromatic (PAN) mode, with a resolution of 0.5 m, and the product level is L2 orthorectified imagery.

The WorldView remote sensing dataset from the Integrated Joint Remote Sensing Observation Experiment for Eco-Hydrological Processes in the Heihe River Basin was obtained through commercial procurement.
