| Abstract |
Clear scattering radar images can obtain even if the area is covered by clouds and dense vegetation. Geological features, such as lineaments and circular structure, are succes$dly identified at southwest of Negros Island, the Philippines, by using such radar images. We are now studying intederometry analysis of SAR {Synthetic Apature Radar) images that provide 11s few centimeters present day crustal movement and thus applicable for monitoring of land subsidence of geothennal area. Good correlation between annospheric and ground temperatures are recognized by the ground truth thermal ig?ared survey of Thauhara area, New Zealand. It becomes basic data for planning heli-bone remote sensing infrared survey. Remote sensing using conventional spectral data also useful for geological analysis. Combined with soil gas survey, oil and gas showing zone is selected in China. Our studies are not limited for geothennal areas but the remote sensing techniques described above can easily be applied for geothermal exploration and environmental problems. |
