In general, most of the GIS only deal with materials and geometric data which just include position, radius, length of the structure. Therefore it's hard to get corrosion data from it. But the one that an owner of metallic structures want to know is the integrity of the structure. Cathodic Protection System can not protect corrosion on the underground facilities perfectly but protect corrsion effectively. It therefore is necessary to monitor the facilities continually So, we need the development of GIS interconnected a corrosion prediction system on the view point of the efficiency of operation and the protection for a big accident. The results of the development of its system are described in this paper. It can do life prediction and interference analysis and also newest corrosion data should be updated regularly.
