基于Java和MapObjects的地理信息系统开发技术剖析

主要分析和阐述了基于 Java和 Map Objects开发应用型地理信息系统的技术 ,介绍 Map Objects-Java Edition的特点、主要功能和开发步骤 ;并以南京市中山陵园古树名木地理信息系统的开发为例 ,对基于组件技术开发应用型地理信息系统中的一些具体功能的实现作出分析 .实践表明 :基于 Map Objects-JavaEdition开发应用型地理信息系统的方法既集中了可视化软件开发工具与地理信息系统工具软件的优点 ,又可以跨平台运行 (可以运行在 Windows、Linux、Unix等操作系统 ) ,有利于节省系统开发费用 ,为快速定制各专业独特的应用型 GIS提供了便捷的手段 ,在应用型 GIS的开发中将有更加广泛的前景

Analysis and development of geographic information system based on mapobjects for java

The ESRI`s OCX named Mapobjects-Java Edition has been introduced. The applications of geographic information system based on Mapobjects-Java Edition has been studied. A case in point of application GIS for ancient and precious trees in the scenic park of Dr.Sun Yat-sen`s Mousoleum, some functions based on Mapobjects-Java Edition have been analyzed. The conclusion shows that MapObjects-Java Edition is a rich collection of client and server components for Java developers.It can be easily extended with our own custom functionality. Combined with the platform independence of Java,this allows us to deliver a powerful, integrated data management and GIS solution over the Web.Component GIS(Com GIS) becomes a chief development model of GIS. Com GIS integrates GIS with special model so closely that it can accomplish not only some functions of GIS but also many functions of the special application; and it can be platform crossing and extendable. There will be a good future for potential application of Com GIS.
