摘要
对NASA World Wind进行了简要介绍,从数据组织、渲染策略、数据缓存等方面进行了架构分析,并深入研究了4D产品、地名地址、地物模型等专题信息在三维地理信息系统中的应用方式。研究表明,基于World Wind构建三维地理信息系统,兼顾速度与效果需求,具有广阔的前景。
This paper gave a brief introduction of NASA World Wind, and analyzed the structure from data organization, rendering strategy, data caching and other aspects. And then, the paper studied the application methods of thematic information such as 4D products, names & addresses, models in the 3DGIS. The result shows that 3DGIS based on World Wind meets the needs of the speed and effect, and has a broad prospect.
