The Research And Development Of Highway Basic Geographic Information Management System

The Highway Basic Geographical Informational Management System (HBGIMS) is a basic business platform. It uses the Road Geographic Informational Management in GuangZhou as its business object, the ArcGIS as GIS's development platform, the WebGIS technology, Distribute Component Object Model (DCOM) technology, Space Database technology, and Dynamic Segmentation technology etc., as its technological instruments. The System (HBGIMS) has many advantages, such as multi-window displaying, database management, visibilization, and it also supports multi-user. The System has set up a business platform of highway management. It can inquiry and count the basic information, and what's more, it can provide the function and interface that the further maintaining management, highway administration, network charging, and calamity need.Aiming at the user's business demand of analysis the functions of the System, the HBGIMS is divided into the following seven modules: data management, view, figure management, inquiry, count, system maintenance, equipment management, and plus a Highway Geographical Informational Network Inquiring System.The article elaborates detail systematic user demand analysis, the establishment of the architecture, the design of all modules, database design, development and realize of business tier COM etc,and introduces systematic unusual handling, operation environmental and major operation form. The paper summarizes finally for the research of paper as well as put forward further research idea. The system realizes swift and accurate graphs, mutual-check data, statistics, charms generating, Graph-data integration of reservation, management and application, as well as Intuitive dynamic display of the highway figure, real-time positioning of highway mileage, and prompt measurement of the distance, Swift online inquiry and browse of highway road-condition information and graph information.The system will offer a basic geography information the management concept of platform, the management platform of convenience and science for Guangzhou city highway department, will establish unified and shared database application platform for Guangzhou city highway department management department to engages in highway program, construction, graph editor, maintenance, road management, and will set up the foundation with solid structure to realize highway management modernization.
