South-to-North Water Diversion Project is by far the world's largest water conservancy project, not only the size of the project a huge, across geographical long technical level requirements and tight schedule requirements, but also covers a wide range and complexity of the relationship, so in order to achieve a more scientific and effective management in the works The introduction of advanced project management and scheduling functions, scientific management imperative works. Number of South-to-North Water Diversion Project, many types, both the spatial distribution of another tense variation of the characteristics of both real-time and historical data, therefore the use of the advantages of GIS spatial data management and analysis, the development of a processing graphical information, management massive spatial data, the functional practical management information systems, to improve the efficiency of project management and decision-making level, has a very important role. Henan Province, south-to-north water diversion project management research instance, mainly do the following: (1) geographic information system applications in hydraulic engineering and management system based on access to domestic and international literature, demonstration of Henan Province, south-to-north water diversion project management the necessity and feasibility. (2) The main content of this paper is to system development, system development goals, design principles, functional design, database design, interface, and input and output design detail. Given specific development process of the realization of the principle of some of the features of the system and the specific method, and finally show the results of the system development. (3) component GIS technology is a state-of-the-art GIS technology developed in recent years, the system uses the component GIS technology, use of the objects VB programming tools and components on SuperMap Objects-oriented development in Henan Province of South Geographic information system, the system is a combination of the operation of the data and maps with information timeliness, you can update the data at any time, based on the need to produce a variety of thematic maps. Mainly to complete spatial visualization, integrated query results output, thematic mapping, various types of spatial analysis, statistical calculations, data entry and editing functions. The whole is divided into the document management module, map editing module, map control module, the information queries positioning module, a statistical analysis module, and a database management module. Through this way of development based on GIS (SuperMap Objects), relational databases, Microsoft Excel data management, analysis of the application of GIS systems have efficient and seamless system integration, program runs less memory, the system is easy to operate, fully functional, development costs low system stability, running speed, data confidentiality (data management permission to sub-administrators and ordinary users), the interface is beautiful and generous, humane, user-friendly operation, etc., only to make up for the traditional MIS visualization on deficiencies, and give full play to the advantages of GIS technology, spatial visualization and spatial analysis functions.
