摘　　要：随着地理信息研究的范围从地表覆盖延伸至地下空间,地下管网的表达和分析成为当前研究的热点。以符号化表达为主的传统地图在地物表达时不够生动直观,本文尝试将地下管网与实景地图相结合,提出了一种基于实景地图的表达方法,研究了线路路由、视口同步和嵌入方式等关键技术并加以实现。实验证明该方法具有较好的表达效果,能够为用户提供更多、更好的地理信息服务。With the research scope of geographic information extended from the surface to the underground space,the expression and analysis of underground pipe network is becoming the focus of current research.The traditional map which mainly uses symbolization for expression is not vivid and intuitive enough.This paper tries to combine the underground pipe network with Real Scene Map,the author proposes a method to express underground pipe network based on real map,researches the key technology such as line routing,synchronous viewport,embedding mode and implements it.The experiment proves that this method has better effect for expression,can provide more and better geographic information service for users.
