Researh Of National Geodetic Survey Database's Web Platform Construction

National Geodetic Survey Database is an important part of National Spatial Data Infrastructure (NSDI) - National Spatial Data Infrastructure database. National Geodetic Survey Database's construction is an important content of Geodetic Survey informationization work.With the development of Internet technology, the formation of new Geodetic Survey System and the development of 3S (GIS, GPS, RS) technology, the work of Geodetic Survey informationization are faced with new technology, applications and service environment.The construction of National Geodetic Survey Database's Web platform, can comprehensively improve the Geodetic Survey achievement's sharing, interactive, viewability,realtime, to make better use of Geodetic Survey information resource, enhance socialized production and service capabilities of the positioning control information, meet the needs of modern Geodetic Survey's production,development and services.The system successful applies the Web technology and the GIS technology in the Geodetic Survey information management and the application.As a major technique personnel of National Geodetic Survey Database's Web platform construction, the author participated in the design and the development work in the system construction. Practical work-based,the author conducted a comprehensive study on the implementation of the system. In the paper,the data analysis, database design and implementation, system design and implementation three aspects of the National Geodetic Survey Database's Web platform implementation was described, The selective analysis spatial data management, the Web platform system and the map service realized the method.Based on analyzing the status of National Geodetic Survey Databases, the technical environment's change and the Geodetic Survey enterprise develops, the author put forward the concrete proposal to the National Geodetic Survey Database 's further development.The paper research content will have certain reference value to next state-level and the region level Geodetic Survey Information System's construction, will have the positive function to the Geodetic Survey Information System's further development.
