This paper will discuss a terrain analysis method using two kinds of remotely sensed data, namely JERS-I/OPS and RADARSAT/SAR which is designed to improve accuracy. There have been many developments in terrain analysis using remotely sensed data. Most of them have employed obtained by two optical sensors. But the data has been influenced by weather conditions because the earth's surface could not be observed through cloud cover. Recently, CCRS launched RADARSAT which had a synthetic aperture radar (SAR) adapted with many incidence angles and spatial resolutions. Using SAR, we can observe the earth surface independently of weather conditions because the sensor can produce radiating electromagnetic waves automatically. However, the accuracy of the results using SAR data was not sufficient because some information was lost due to layover, which is a special phenomenon of SAR. Therefore, I propose a terrain analysis method using OPS and SAR for making use of the advantages of the two sensors and applying the method to real data.
