A Reseach On The Geography Information System Of Land Resource Based On Components

Geographical information system has been rapidly developed in both theory and practical applications recently. It has been developed into a cross-subject, multi-directions research area. Applying this technology to the management of the information of country resource can greatly improve the quality and efficiency of the management issues. The system also helps to improve the accuracy and the timeliness of the management of information thus provides an effective and reasonable way to use the land resources. The department of the land resource in Shunde City launched a project to develope such a geographical information system to help in improving the management of the use of land resource. Our project team took in hand this project. Then our team began to integratively apply the knowledge of informatics, computer science, software engeering and land resource administration to research on the information system of Shunde land resource oriented by systemic theory of science. Based on the analysis of the business of the department involved and the customers' needs, the project team used object-orient methods and main GIS (Geography Information System) platform to develop a system based on the GIS platform for the department. In terms of the functions, this system provided a graphic analysis for the data and enhanced the informational aspects. It met the needs of the customers and also achieved the automation of the information management. Thus, it greatly increased the efficiency of the management and also increased the transparence of the process. In practical use, it greatly helped in saving cost and more importantly increased public's satisfaction. The outstanding of the system was to achieve the effective interaction between the GIS technology and the theory information systems while deeply analysis the business of the department. In the development of the system, lots of new techniques had been used, such as component GIS, VS.NTE based control development and so on. This also led to a new and positive research and trial for the development of the information system for the land used.
