利用ARC SDE空间分析函数扩展World Wind Java空间检索能力的方法研究

Research of Extensions of World Wind Java Spatial Retrieve Capability by ARC SDE Geometric Analysis Function

World Wind Java是一个优秀的开源代码三维地理信息开发平台。与其他三维地理信息平台类似,World Wind Java同样面临以WMS格式发布的海量矢量数据拾取与空间检索需求。本文利用ARC SDE提供的空间数据检索函数开发的服务接口扩展实现了World Wind Java的空间数据检索功能,并在“北海区海洋综合信息一张图”系统中进行了实际应用,验证了方法的有效性。

World Wind Java is an excellent open-source GIS development platform. Similar to other 3-   dimensional geographic information platform, World Wind Java faces the same question for ele-ment picking up and spatial analysis released in WMS. Spatial data using the ARC SDE provides the retrieval function expansion of the World Wind Java data retrieval function, and practical application in the “North China Sea Integrated Ocean Management Information System” system, and verifies the effectiveness of the proposed method.
