This dataset is contains orthorectified imagery from the Advanced Visible and Near Infrared Radiometer type 2 (AVNIR-2) sensor on-board the Advanced Land Observing Satellite (ALOS) "DAICHI".

The AVNIR-2 ORI product was created from AVNIR-2 1B1 data after stereo matching with reference to ALOS's Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM)-derived DSM AW3D30. The orthorectification process used AW3D30 DSM data when available and SRTM (The Shuttle Radar Topography Mission) DSM data otherwise.

该数据集包含来自高级陆地观测卫星 (ALOS)“DAICHI”上的高级可见光和近红外辐射计类型 2 (AVNIR-2) 传感器的正射校正图像。

AVNIR-2 ORI 产品是根据 AVNIR-2 1B1 数据在参照 ALOS 的立体映射全色遥感仪器 (PRISM) 衍生的 DSM AW3D30 进行立体匹配后创建的。正射校正过程在可用时使用 AW3D30 DSM 数据，否则使用 SRTM（航天飞机雷达地形任务）DSM 数据。
