We represent the monitoring method of a carbon sink preservation activity for the global warming countermeasure using a high-resolution satellite image. We first investigate the satellite image availability and make a plan of a satellite image acquisition order. Next, we propose the land-use classification using the object-based image analysis to monitor carbon sink forest. Lastly, we apply the technique...
Natural and crop vegetation phenologic data become indispensable when creating thematically and geographically detailed maps through satellite images classification. Several date acquisition is necessary to achieve this cartography. However, the presence of clouds, shadows, snow, etc, is usual when many different dates are used and that fact implies an important loss in classifiable surface. This...
After launching the Advanced Land Observing Satellite (ALOS) with three earth observing instruments (PRISM, AVNIR-2, PALSAR) on January 24th, 2006, Japan Aerospace Exploration Agency (JAXA) has completed an initial spacecraft checkout for three and half months and started initial Calibration and Validation activities for coming five months. In parallel, JAXA has been checking the ALOS ground data...
This paper describes the initial results of the PALSAR characterization using the data acquired in the commissioning phase for the five modes of FBS, FBD, DSN, SCANSAR and POL, and using the active radar calibrator deployed at the calibration site in Japan. This paper also describes the radiometric and geometric performances of the PALSAR images shortly. This paper will end up with the parameters...
PALSAR L-band SAR will be affected by Faraday rotation. In this study, PALSAR system is briefly described, and the Freeman calibration method is considered for PALSAR calibration. However, this method requires the deployment of a minimum of one corner reflector (CR) for the calibration of each scene, and this is not convenient in practice. In this paper, the use of human-made and natural symmetric...
