Paper Abstract

The Advanced Land Observing Satellite (ALOS) was successfully launched on January 24th, 2006. This paper introduces the preliminary results of calibration and validation for two optical sensors of ALOS i.e., the Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) and the Advanced Visible and Near Infrared Radiometer type-2 (AVNIR-2). PRISM consists of three independent panchromatic radiometers, and is used to derive a digital surface model (DSM) with high spatial resolution, which is also an objective of the ALOS mission. So, the geometric calibration is important in generating a highly accurate DSM by stereo pair image of PRISM. The radiometric calibration is also important for AVNIR-2 as well as PRISM. The relative radiometric calibration is carrying out using acquired images over homogeneous targets such as ocean, deserts, ice and snow areas and the nighttime observation. The absolute radiometric calibration is applied the cross calibration method using calibrated satellite images i.e., MODIS onboard Terra/Aqua satellites, ASTER, SPOT-5 etc. In this paper, results of the first images acquisition and preliminary analysis for calibration and validation are described.
