Satellite images have their own advantages of synchronous and regionally wide observation on whole earth surface. Under uniform conditions in data acquisition by satellite in the space orbits, advantages are also available in multi-temporally repetitive observations at same locations and in optically multi-spectral or microwave transparent specifications. In turn, there are a few disadvantages of low grade in time and spatial resolutions, low dynamic range of intensity with signal noise, and ambiguous characteristics of the target nature. Geological features can be observed in images interpreted by geologists who use images for the first-step evaluation and assessment of the target of exploration as well as environmental monitoring. The remote sensing technology applied to the resource exploration, we integrate the spatial, spectral, and structural characteristics of satellite image data combined with GIS, which currently provides the utilization of web-GIS in the internet. The application of large scale data currently available clearly needs the appropriate information management of the search in data mining in servers and the maintenance of security. This paper provide the recent experience of satellite remote sensing to be applied to the resource exploration with special emphasis of the information management.
