NASA World Wind JavaSDK数字地球客户端开发
|
摘要
NASA World Wind是美国航空航天管理局(NASA)推出的一个开放源代码的地理软件,一个3D的可视化虚拟地球仪,也是最流行的数字地球平台,因为数据和使用都完全免费,所以值得对其应用进行研究。WorldWind JavaSDK是NASA提供的一个开源的开发软件包,本文对World Wind Java SDK的包和类、如何创建WorldWind JAVA应用、架构、API以及功能结构等做了详细的说明。在此基础上,介绍并展示以Applet和Java WebStart两种部署方式,完全利用World Wind的数据,开发自己的GIS平台,实现对其数据的充分利用。
NASA World Wind is open-source geographical software launched by the United States Aeronautics and Space Administration(NASA),it is a 3D visualization of virtual globe,is the most popular digital terrestrial platform,and because the data are completely free to use,so its application is worth of being researched.World Wind JavaSDK is also open source software,and it is the development tools.In this paper,the World Wind Java SDK package and class,how to create World Wind Java application framework,the API function and the structure are detailed explained.Applet and Java Web Start the two deployment ways are introduced and demonstrated.By taking full advantage of World Wind data,we can develop our own GIS platforms,and achieve the complete and deep use of the World Wind data.
