Description

The ALOS Ortho Rectified Image Product (ALOS-ORI) released by the Japan Aerospace Exploration Agency (JAXA) is open to the public. The ALOS-ORI consists of the AVNIR-2 ORI product compiled from images acquired by the Advanced Land Observing Satellite “DAICHI” (ALOS) operated during the period from 2006 to 2011. NASA, in cooperation with JAXA, makes the dataset available through the ASF DAAC.

AVNIR-2 Ortho Rectified Image Product

The AVNIR-2 ORI product is created from AVNIR-2 1B1 data after stereo matching with reference to the Panchromatic Remote-Sensing Instrument for Stereo Mapping (PRISM) ORI. AW3D30 DSM data, which is created from a PRISM triplet image, is used for the orthorectification processing. If AW3D30 is missing, SRTM (The Shuttle Radar Topography Mission) DSM data is used.

* Please refer to the HDR file in the data file to confirm which DSM is used in ORI product creation.
