摘要
本文在金字塔模型基础上，提出了一种能够快速提供多分辨率影像、支持分布式存储的遥感影像组织模型——瓦片金字塔模型，设计了模型的分布式存储数据结构。分析显示：数据结构支持大区域影像、混合型数据源、瓦片独立压缩和冗余存储配置。
Based on the traditional pyramid model, a tile-pyramid model is proposed for remotely sensed imagery, by which multi-resolution images can be fast provided and distributed storage can also be supported. The data structures of distributed storage for the model are designed as well. The analysis shows that the structure supports images from large area, mixed-source data, independent tile compression and redundant storage deployment.
