Up to now, China has implemented two rounds of national mineral resources planning and accumulated a large number of mineral resources planning data. However, current situation of informatization construction of mineral resources planning is backward relatively. There are still some problems, especially how to research and implement a set of efficient information service system which conforms to the development requirements of mineral resource planning information construction, and making all kinds of users acquire information or services of mineral resources planning by a network on-demand is a problem that deserves thorough research. Through the study on current situation of informatization construction of mineral resources planning, and on the basis of analysis of the GeoData Service's technical features and advantages, this paper proposes to build the Mineral Resources Planning Information Service System (MRPISS) which adopts three-tier B/S model with the service-oriented concept in order to solve those problems above. Firstly, the paper focuses on the detailed design of the system's logical structure, spatial database and functions. Secondly, it describes the key points in the system building, the processing method and the method's technical advantages of the GeoData Service, which the results of the mineral resource planning data is packaged into. Besides, the practical running effect of the system which is developed with the technology of ArcGIS Server.NET ADF under the Dotnet framework is demonstrated. Finally, the paper analyzes how to implement some key technologies in the system, such as the asynchronous callback technology of Web ADF, the dynamic navigation of Web based on JavaScript, the data access technologies of ADO.NET, the optimization of the system performance and so on. The running results of the Mineral Resources Planning Information Service System built in this paper shows that it brings a change which from Web GISystem to Web GIServices on the approach of the system architecture in the fields of informatization construction of mineral resources planning, and provides a new application model for synchronous update, remote extraction, sharing and management of the mineral resources planning data under a distributed network.
