【Abstract】 Geographic Information System (GIS) has been widely used in China. It plays more and more important role in the management and planning of environment and equipment resources, and it is gradually evolving to be an innovative information industry. Looking forward to the 21st century, while a new digital society and cyberspace era is coming, Geographic Information System will play more important and active role in the national economic development than ever before.Geographic Information System is the computer system which collects, stores, manages, analyzes, describes and utilizes data related to the whole or partial of earth’s surface, geospace and geographic distributing information. It is the synthetic composition of computer hardware, software, database and customer. Its main function is to collect, edit, manage, analyze, make statistics analyze and plot geospace data.The implementation of the Cadastral Management Information System is the synthesis of database technology, network technology, GIS (Geographic Information System), system integration technology and other technologies. GIS based Cadastral Management Information System is the best choice of dealing with graphic processing and graphics-documents combination.System features:1 . The system database model supports a full set of topology characteristic, provides all the advantages of large database management and implements the real massive data management.2.The system provides the time dimension concept, utilizes the optimized data structure and algorithm to manage the data of land and guarantees a highly efficient customer searching on the historical land information.3.The system adopts the standard database structure of the Ministry of Land and Resources. It is easy to communicate the data with other operational systems of the Ministry of Land and Resources or other parties.4.The system provides powerful updating tools, so that it is very easy for customers to do daily operation and cadastral data updates.5.The system combines the C/S and B/S technologies and integrates the cadastral management with office automation flow efficiently.Powerful technology support:1.The system utilizes the world leading software ARC GIS as the GIS platform. It is the fusion product of many advanced main stream technologies, including COM groupware technology and object oriented secondary development environment; it provides long transaction management and version management; it utilizes the open standard and management method of the commercial RDBMS database. All these guarantee the technical advantage of our cadastral management system.2.The system builds its data management on the large network database ORACLE. ORACLE is considered as the best database and has the biggest market share world wide. It supports increasing load requirement and provides the necessarily reliability, extensibility, security and easy of use on the massive GIS data. It provides redundant data protection and efficient data storage mechanism; therefore it allows the customers to retrieve information with high efficiency. 3.The system retrieves GIS data with the Spatial Databases Engine (SDE). It provides all supported customer with special data services; it continuously and seamlessly manages the large geographical element data; it also provides highly efficient data operation service on spatial or non-spatial data.Application perspective:1.Land management: This system uses the new technologies to make the land management more scientific and rational than before. It can advance the accuracy of land management data and makes the land management data easy to analysis.2.Urban development: This system can effectively direct all kinds of urban developments by providing systematic information on location decision and optimization as well as construction management for major urban development proposals and projects.3.Urban management: Cadastral Management Information System is management oriented; it can provide accurate and intuitive management data for all related institutions. It can help to realize the computerized information management and modernize the urban management.4.Auxiliary Decision Making: This system can provide information on urban planning, development and management to support the scientific decision making process of the government.The future development of the system:1.We need gather and update new data while applying the system, continuously enrich the database contents; further coordinate and optimize data processing structure. We need further enhance the system integration level, advance the technology fusion of the computer network, database, GIS, RS and DSS; provide more powerful support on dynamic data updating, synthetic analyzing and decision making..2.Internet based system. It is a trend to develop application systems with internet technologies. Web based GIS not only can be used by the government agencies, but also can be used to transmit the information to every household.With the development and improvement of information technologies, especially the application of Internet/Intranet technology, Cadastral Management Information System will widely use Client/Server technology, CAD technology, OLAP technology, artificial intelligence and expert system technology. It will evolve from a simple data processing system to an intelligence process system. It will provide an important base for our country’s information development on“digital city”and“digital country”construction.更多还原
