Traditional geological mapping work is tedious with repeated trivial manual jobs, it often wastes very long time and it is difficult to control its data quality. For improving work efficiency of geological mapping and enhancing the data quality of result data, China Geological Survey paid much attention to the intelligent geological mapping problem focused by foreign geological surveys in geological informatization field. iMapower is developed by integrating MapGIS, mapping standards, software engineering, database and artificial intelligence together. It is an advanced intelligent geological mapping system for geological survey generalization. iMapower employs an interactive work pattern using geological expert knowledge as main line with limited experts' interaction. This computer-aided application system is able to perform massive different scales geological map generalization and thematic map making through manipulating raw data of original geologic map using various intelligent map generalization algorithms such as merging, simplification, fusion, smoothing, etc. iMapower was used in latest 1.5 million and 2.5 million geological maps compilation work. The production practice shows iMapower can save at least 65 to 75 percent of mapping time, reduce workload of mapping staff sharply and improve data quality significantly. iMapower which based on MapGIS has been published in GeoCloud and it can provide technical services for geological survey, resource planning, geohazard emergency, ecological protection, etc.
