PRODUCTS OVERVIEW

Introduction

This section gives an overview of the products generated by the ADEOS AVNIR Processing Subsystem (AAPS).

The AAPS is a software system which executes on a SGI Challenge host processor. The AAPS accepts raw (level 0) sensor data (AVNIR), performs radiometric and geometric corrections, and generates products at various levels of correction (level 1A, 1B1, and 1B2).

There are two types of products generated by the AAPS:

  • imagery products
  • reports

Imagery products are tape (see D-1 Cassette Specifications for a description of this device) or disk products (including the subsampled imagery and histogram disk product) containing satellite imagery. Reports are fixed format disk files which are produced by AAPS.

Imagery Products

The AAPS generates level 1A, 1B1, and 1B2 products as described by in Reference Document A-2 with a range of geometric and radiometric corrections.
Each AAPS imagery product contains a single corrected full scene or subscene of satellite imagery. AAPS imagery products may be generated on tape or disk.

AAPS Reports

The AAPS produces three reports as a results of product generation: The Product Order Report, the Product Order Log, and the Image Navigation Processing Report.
