Research And Implementation Of Traffic Geographic Information Release System Based On WebGIS

With the continuous development of computer technology and the deepening of theresearch of GIS application, the network technology and geographic information system, topromote the geographic information industrialization and popularization of the goal of rapiddevelopment, so the application research of geographic information system in a direction,namely the network geographic information system. Network geographic information system(WebGIS) technology is introduced into the transportation information industry to solve theincreasingly serious traffic problems, accelerate the pace of the urban traffic information, thenaim was to promote economic development. Using WebGIS technology development trafficgeographic information release system, to ease urban congestion, satisfy the mass travel hasimportant practical significance.In this paper, based on the.NET environment, using ArcGIS Server as the GIS platformfor the development of Fujian province traffic geographic information system. From theconcept, characteristics and theoretical basis of WebGIS research is applied to the process ofsystem development and implementation of related technology, finally realizes the thesisdescribed the traffic geographical information system, This article mainly from the followingseveral aspects of research:1、Traffic geographical information system at home and abroad is discussed, and thedevelopment present situation, based on WebGIS research theory to analysis and comparisonof WebGIS system several implementation scheme, and choose the system developmentplatform.2、 The Ajax technology, the technology is applied to implement asynchronoustransmission of data between the client and the server.3、For ArcGIS Server theory study, a detailed analyze the map cache technology.4、System module design and implementation, to provide users with the provincialtransportation information, general information and geographical elements within the territory of the shortest path query information, etc. For traffic geographical information system hasmade the beneficial exploration in practice, and has set up a simple traffic geographicinformation release system, also provides for the development of other traffic informationsystem.
