Second edition, June, 2020

1． Introduction
1.1

PurposeThis paper provides the user with a description of the ALOS / AVNIR-2 ORI (Ortho Rectified
Image) product output files.
ORI product – ORI data generated from the AVNIR-2 image of standard product Level 1B1
with DEM / DSM data set.

2． Overview of ORI product2.1

File structures of ORI product

The ORI product consists of Browse Data File, Header File and its corresponding Data File.
The ORI Data File is separated into each bands and is in GeoTIFF format raster image. Fig.
2-1 shows the ORI product file structure.

Fig. 2-1 ORI product file structure
The Header File includes text information of its corresponding Data Files which provides
users with a size of Data Files, format, geo-location information, etc. The detailed format of
Header File is described in section 3.2. The ORI Data is the image data of 8 bit unsigned
integer.
