摘要
针对遥感卫星影像数据存储管理的迫切需求,研究了海量影像数据组织管理中存在的主要技术问题,提出了一种基于线性四叉树技术的影像金字塔模型快速索引机制,并运用关系型数据库技术实现了遥感影像数据与元数据的一体化管理。最后讨论了海量影像数据管理系统实现技术,并通过试验数据验证了技术方法的实用性。
Aiming at the requirement of satellites massive remote sensing image data storage and management, this paper discussed the key technical questions at massive remote sensing image data management. By the study, it put forward a quick indexing mechanism which is an image pyramid structure model based on a linear quad-tree technical way, and carried out the integrated management between remote sensing image data and metadata by the relational database technology. At the end of paper, it analyzed the technical ways of building a system of massive remote sensing image data management, and proved the practicality of that way through an experimental data test.
