The Design And Application Of Fuzhou Forest Park Management System Based On GIS

Geographic Information System(GIS) technology is a hot area of computer technology in recent years to promote the military, transportation, urban planning, energy, telecommunications, environment, agriculture, mapping and a series of changes in the industry, has become an important means of support forest park management. In this paper, the GIS technology and components to solve Fuzhou National Forest Park management.Since the component technology supports flexible, powerful, easy to secondary development characteristics, often combined with GIS technology, called Component GIS. Component GIS GIS is actually the various functional modules are divided into a number of controls. Wherein each control different functions.The system uses as MapObjects map component. Simple Object Library structure MapObjects, the powerful support of the development of language Windows operating system, such as C #, JAVA, VB, VC. Here the main use VB as software development language. MapObjects application by adding a variety of control operations map.The spatial information into a professional digital software Raster2 Vectorector generate Fuzhou National Forest Park Management System required graphic data. By vector map of Fuzhou National Forest Park is corrected, the error can be reduced, can be obtained spatial database more realistic situation. In order to make more accurate property database, we also need to sort out the property sheet. The system uses a relatively simple Access as a database system, and uses ADO to enable fast access to the database.To Fuzhou National Forest Park road network shortest path analysis, after which the digital road map, the arc and the node is an abstract view of the formation of the network topology. The shortest path algorithm using Dijkstra algorithm for computing the shortest path between two nodes.Taking into account the characteristics of the system, the system selection as ordinary PC hardware platform, select Windows 7 as the operating platform, choose Microsoft Access as the database platform. The system uses MapOjbects as a GIS component, using VB as a development language.This paper studies how to use Visual Basic and MapObjects GIS based Fuzhou National Forest Park Management System. To achieve the operating system layer of this chapter, the map operation, Hawkeye, query, map editing and other important functions via codes have been described in detail, and gives presentation renderings.
