基于Eclipse的移动客户端地图浏览软件开发

本文在对移动客户端地图浏览软件研究调研的基础上,分析了现有移动手持设备地图浏览软件的功能及其开发技术,总结了Eclipse和Mobile SVG在移动设备上开发和应用的优势,并提出如何运用Eclipse、EclipseME及SVG Tiny构建3G手机上的地图应用。本文将J2ME、SVG技术融合到移动GIS中,以Eclipse为开发平台,SVG为地图表达语言,用XML描述属性信息,调研了手机客户端地图浏览器的基本功能,且在3G手机中实现了地图的浏览与简单的查询,并用模拟索引机制和序列化方法实现本地数据的有效管理。此方法对今后的移动地图服务有着广阔的应用前景。

Study of Map Browser on Mobile Devices Based on Eclipse

We reviewed the actualities of the map browsing software in the mobile client,and then summarized the functions of the current map browsing software in the mobile devices and the developing technologies.We summed up the advantages of the way to use Eclipse and Mobile SVG on mobile devices,and proposed that how to design map application on the 3G phones based on Eclipse,EclipseME and SVG Tiny.In the paper we integrated J2ME and SVG into mobile GIS,using Eclipse as development platform,employing SVG as map expression language and applying XML to describe attributes.We inquired basic functions of the map browsing software in the mobile client,and then realized the browsing function and simple query function on the 3G phones.To manage the local data effectively we employed the simulation indexing mechanism and serializing means.We believe that this technology can be widely applied to mobile map service in the future.
