How to organize, process and analyze the comprehensive data of ore finding is very significant for effectively delineating “5P” area based on t he theory of geoanomaly. A new technique of MultiS Integration provides an insight and a strong tool in this field. The author suggests that multiS integration should include some subsystems such as GIS (Geograp hic Information System), GPS (Global Positioning System), RS (Remote Sensing), VS (Visualizing), ES (Expert System), etc. Based on computer network, these subsystems are integrated by specific software and hardware. For various purposes of application, some corresponding techniques of collecting, managing, exploring, processing and applying data are selected to facilitate the multiS system. Current studies have demonstrated that this integration technique is an active operating system to process various information of oreforming and orefinding, which will yield identical results and consequently promote the efficiency and precision of delineating “5P” orefinding area.
