摘要
网络三维影像地图在全球的推广改变了地理空间信息的原有服务模式,促进了地理空间信息的共享和服务水平的提升,成为当前地理空间信息服务领域研究的热点。栅格数据作为影像地图系统的基础数据,它的高效组织是系统成功的关键。本文将对网络三维影像地图系统的栅格数据组织过程中的关键问题进行分析,结合实际提出一套解决方案。基于本文的方案组织"神州遨游"系统的栅格数据,取得了较好的效果,对同类软件的开发具有参考意义。
The expansion of the network three-dimension image map all over the world has changed the service pattern of geography space information. Meanwhile, it has promoted the share and service of information and become the hotspot in the current research domain of geography space information service. Raster data is the basic data of image-map system, whose efficient organization is the key of our system＇ success. This paper will analyze the important problem of the raster data organization in the three-dimension imagema Psystem. Finally, it brings forward an effect solution.
