Design Of The Thermal Line Geography Information System Of Trade And Economic DepartmentJ In Zhou Teacher's School

Directed at the present characteristics of the thermal line geography information system, and based on full understanding of its service nature and procedure demands, Geography Information System is a new technology which combines computer graphics with database, and stores up deals with space information. GIS can unite geography location and relate attribute with some methods. According to demand of customers, the system will export space and attribute information to customers lively., and with the help of unique space and visual express function, GIS can do all kinds of assistant decision-making.According to the requirement of Trade and Economic departmentJ in Zhou Teacher's school, the researchful purpose of the thermal line geography information system is focus on the meaning of the system extent,This article gives detailed introduction of the needs of the project overall plan the function of the system and the design of the technology, tells about the techniques and ways to use the system.The system adopts a lot of important techniques, such as map delamination vector abstract space data attribute data and so on. Based on these techniques and ActiveX technique, we research on GIS and develop concrete line manage information system sortware. The applying program adopts win2000, developed by Visual Basic, an object-oriented visual programming language and SQL Server2000 SpaceDataBase MapX and so on. This system has the character of rapid development and credibility of running. With this technology we can achieve safety briefness and easy maintenance, meanwhile.
