Abstract：GIS is used widely for its power in spatial data management and representation, but has been insufficiently employed in geological project management. With the construction of the projects management system in Strategic Mineral Prospect Survey as an example, the authors have analyzed the characteristics of the geological projects management, and proposed a technology which uses the ESRI Mapbjects 2.2 a geographic information system component to construct the system for managing the attribute and spatial data. In addition, a geological projects management system is developed and used in several projects management departments.
