  本数据集为机载WiDAS传感器于2008年06月01日获取，地点在张掖-盈科-花寨子飞行区。 \n

\n

  原始数据经过几何校正、辐射定标和大气校正后发布，面向普通用户的数据产品为Level-2C产品（经过几何校正、辐射定标和大气校正），以及Level-1B（波段间配准）快视图和Level-2B（波段间配准）快视图。\n

\n

  原始数据（Level-1A数据）和数据处理参数存档，需提交申请并通过审批后才能获得。 数据处理时间为2008年8月-2009年4月，完成时间为2009年4月，2009年11月做了一次CCD相机辐射定标的订正。\n

  The original data of this data set includes 12 routes. Due to the unstable instrument state, some routes were re flown. The imaging time of 650nm and 750nm bands of the data CCD camera on that day has a deviation of about 1.4 seconds from that of 550nm and 700nm bands. It was registered in the preprocessing process, but there is still a certain degree of band registration error in the area with large elevation change.
