摘 要
当今GIS应用已经广泛于森林管理、城市管理、车辆导航等领域。目前开发GIS系统的技术与软件种类繁多,建立一个GIS应用系统的费,怎样选用新的技术开发GIS系统,怎样减少开发的难度与降低开发的费用,是一个值得思考的问题。在GIS开源领域,选择开源GIS软件是一个不错的选择。本文首先介绍了开源GIS的现状,并介绍开源GIS开发平台,例如OpenStreetMap,GeoServer,OpenLayer等,在此基础上重点介绍OSGeo的Web GIS开源项目Geomajas,及其内部架构和关键技术。Geomajas中使用的渲染方式geomajas中OGC的SLD标准,Geomajas中使用空间数据工具Geotools,数据网格技术Infinispan等开源技术。其次对Geomajas与其它常见Web GIS开发平台的空间数据编辑功能对比,分析常用的几种Web GIS 框架。对Geomajas的图层插件进行了扩展,实现了对我国的天地图的地图瓦片的加载以 Geomajas为框架并在此集成框架基础上开发了基于大棚信息管理系统应用。在全文基础上,提出本文不足及后续研究。

Todays GIS-based application has been widely used in many fields such as managing a forest,managing a city,routing vehicles. arallel development of commercial and non-commercial GIS, with different features. So there are a lot of technology and software to build a GIS based application, and face the difficult to establishment of a GIS application with the large?costs, how to the use of new technology development a GIS and reduce the difficulty of development and the development cost is a question worth considering in practice. In GIS open source filed, open source GIS software is a good choice.
This paper first introduce?the status?of?open source?GIS?and?a brief introduction?to?open source GIS development tools,?such as?OpenStreetMap,?GeoServer etc. After that then introduce?the OSGeo open source project?Geomajas which is a enterprise web GIS?developer framework for GIS developer to create Rich Internet application.
