基于ArcSDE和Windows服务的WebGIS动态数据可视化技术研究

The Visualization of WebGIS Dynamic Data Based on ArcSDE and Windows Service

本文论述了一种采用ArcSDE9.3、Oracle 10g软件存储与管理静态、动态空间数据,使用ArcGIS Server9.3.1软件管理与发布优化地图服务,采用存储过程和Windows服务等技术实现动态数据的自动实时更新与维护,使用Ajax技术实现页面局部刷新,提高用户体验的综合技术方法。采用该技术方法构建了高速公路交管信息可视化系统,实现了实时交通流可视化、实时交通管制信息可视化等功能,验证了该技术方法的可行性与实用性。

This paper describes a comprehensive method of visualization,using ArcSDE 9.3,Oracle lOg to store and manage static and dynamic spatial data,using ArcGIS Server 9.3.1 to manage and publish optimized map services,using stored procedures and windows services to update dynamic data in real time,using Ajax to improve better user experience.This paper also describes a highway traffic control information visualization system based on the comprehensive method described above.System＇s functionality includes real-time traffic flow visualization,real-time traffic control information visualization and so on,validating the feasibility and practicality of the comprehensive method.
