基于SVG的电子交通图的设计与实现

The Design and Implementation of Electronic Traffic Map Based on SVG

SVG是一种使用XML来描述二维图形及其应用的语言,同时它还是一种矢量图形格式,对网络环境下矢量地图数据的共享与传播具有重要意义。本文首先分析了常见的WebGIS平台,然后采用Illustrator组织和生成交通地图数据,最后采用B/S架构,基于SVG,JavaScript设计和实现了电子交通图系统并在IIS中实现了系统的发布,解决了传统电子交通图包含的信息量有限、交互性较差、表现能力不强等问题。

SVG is a language that uses XML to describe two- dimensional graphics and its applications,at the same time it is also a vector graphics format,it has important implications for vector map data sharing and dissemination in the network environment. This paper firstly analyzes the common WebGIS platform,secondly uses Illustrator organizations and generate traffic map data,lastly uses B / S architecture design and implementation the electronic traffic map based on SVG and JavaScrip and releases the system in IIS,the system solves the problems such as the amount of information is limited,poor interactivity,performance is not strong and other issues in traditional electronic traffic map.
