Design and Implementation of Highway Management System Based WebGIS
Network Geographic Information System is a GIS based on Web technical standards and communication protocol of network , a product of Web technology and GIS technology, it is based on Internet / Intranet to provide users with information distributed in space, data sharing, exchange and cooperation. WebGIS make full use of network resources, a large scale to reduce costs and complexity of dealing with the implementation of the server, the client is simple, is an ideal global optimization model, replace a desktop GIS system, and provide personalized service.Based on WebGIS for the new technology platform, the highway pavement management system designs and builds roads spatial database and attribute database. The system uses dynamic segmentation technology to link road geographic information and attribute information. The system could process pavement condition evaluation and forecast by model, the decision support subsystems with analysis and decision-making. Through the establishment of highway pavement management system based on WebGIS, it is to achieve highway management scientific and effective network, it will greatly enhance the efficiency of highway management it is effective management tool to resolve the contradiction between the rapid growth of the highway and the pavement maintenance. It will provide timely and accurate decision support information.
