Remote sensing technology provides ground surface data relatively cheap with large coverage area. However, the application of remote sensing technology for identifying physical properties of ground surface related to geothermal system is still limited. The atmospheric conditions such as cloud and water vapor are always the main problem of the optical sensor as well as the vegetation in tropical countries. On the other hand, the geothermal exploration and exploitation at producing power plant with high success ratio is crucial for Indonesia due to limitation of fossil fuel energy. Overcoming the problem, we proposed a research to identify the ground surface permeability based on surface roughness using Polarimetric SAR (PolSAR) data of The Phased Array type L-band Synthetic Aperture Radar (PALSAR) onboard The Advanced Land Observing Satellite (ALOS). The aim of this research is to find the physical properties of surface such as ground permeability which is the most effective to predict geothermal system bellow the ground surface using active remotely sensed data. Further aim is to increase success ratio of geothermal exploration as well as expansion to the existing power plant.
