基于ArcXML的路政信息发布系统的设计与实现

摘要

为了解决传统参数帧描述WebGIS通信协议的不足,研究了在ArcIMS的平台上,以ArcXML为传输协议的路政信息的网络发布.针对系统生成ArcXML请求信息和解析返回应答信息的不足,结合路政信息的要素特征,提出了ArcXML协议的封装方法.该方法有效降低了系统开发的复杂度,方便了协议扩展和功能扩展.最后,以路政信息发布系统为例,验证了该方法的可行性和有效性.%To solve the problem of Web GIS communication protocol with traditional parameter frame effectively,Web publication of road information through ArcXML transfer protocol on ArcIMS is studied.To overcome shortcomings of resolving ArcXML of request and response information,based on feature character of road information,ArcXML encapsulating protocol method is proposed.This method reduced the complexity of system development effectively and made extensibility of protocol and function convenient.Finally,the publication system for road information is presented to verify the feasibility and effectiveness of the method.
