Abstract

In order to observe the status of earth's nature and human activity, we are able to utilize the sensor data onboard the orbiting satellite platform with high resolution. It is well known that remotely sensed data have quite unique character of quick, repeat, cheap and reliance, which reflect the features of earth's surface. This technique is often utilized for some of exploration stages such as petroleum and metal mining resources.<BR>JERS-1 SAR data were taken over disastered area before and after the Hyogoken Nanbu Earthquake, and generated interferrogram showing crustal deformation pattern. Also, we have derived lineament map from SPOT HRV data to compare with the pattern of interferrogram.<BR>This paper describing the effectiveness of new concept the usage of lineament pattern. Because, extracted plenty of lineaments from satellite image suppose to be more efficient to detect surface movement occurred by crustal deformation.
