摘要: 为了实现分布式异构栅格空间数据无缝集成服务,设计了分布式异构栅格数据的集成管理架构,提出了分布式异构栅格数据集成方法,其核心是建立异构栅格数据索引代理、全局逻辑金字塔结构索引和分布式索引注册中心,实现异构金字塔结构栅格数据的集成、更新和服务。Abstract: We dicuss the key technology of implementing the seamless integration and the service for distribute heterogeneous raster data.Firstly,the architecture for integrating of distribute heterogeneous raster data is designed.Secondly,the distribute raster spatial index and the logical pyramid data structure are presented.Finally,according to these methods,a GeoGlobe-based prototype is tested and some advices are discussed.
