| | Abstract | | The airborne garvity gradient survey is acquired at a short measuring interval which reflects mainly on unevenness of the surface. It helps to estimate the density of surface-layer by the correlation analysis with the DEM. However, its analysis is not be sufficient due to the effects of deeper layers remained in the acquired data. The auther devised the the method of horizontal garvity gradient stack (HGGS) in order to cope with the above obstacles. Tha case studies of the geothermal prospective area as wellas that of the land slide will be presented. |
