Description
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.
