摘　　要：随着获取遥感影像的传感器与获取技术手段的日益先进,遥感影像的数据量空前巨大,这对海量遥感影像的管理与应用提出了更大的挑战。传统的遥感影像库系统在海量数据组织和数据快速检索上已经不能很好满足用户的需求。该文针对遥感影像库目前存在的缺陷提出一种影像组织和检索机制,并结合已经实现的系统验证了该方案的可行性。As more and more kinds of sensors and techniques are used to acquire remote sensing images, the data size of it is so colossal that it is a great challenge to manage the data. However, traditional remote sensing image database system can not satisfy the requirement in huge data management and fast browse of it. In this paper, innovative ways to organize the image data and methods to search it are brought forward to resolve the problem existing in traditional remote sensing image database system. In the end, a system is developed to validate the feasibility of this scheme.
