摘要
现代三维数字地球已成为GIS技术应用的常用前端展现平台,采用的海量高分辨率遥感影像、分层地名数据和DEM数据的数字地球能否提供高效服务成为制约数字地球框架实用性的关键因素。本文对目前流行的由World Wind项目组基于OGC标准实现的WMS服务及通过Geo Server项目实现的地名服务建立基础地理集群服务的方法进行了研究,同时还针对不同分辨率、不同存储模式的的影像数据服务效率给出了实际分析测试结果。
Modern 3D digital earth technology has become a common front-end GIS application platform. Digital earth available in remote sensing image data and DEM data services have become the main factors restricting the digital earth frame efficiency and practicability. This paper presents the methods to establish combined cluster service based the current popular World Wind project team＇s WMS service and the Geo Server project＇s name service,at the same time,this paper also aimed at different resolution and different storage modes of image data service efficiency test results are presented.
