通过研究遥感影像数据特点和分析应用现状,结合细节层次技术思想与影像金字塔模型,以优化的碎片式影像划分算法对影像进行分级分块的处理。按照共享文件目录的方式组织碎片文件,建立基于Web的分布式遥感影像数据发布框架,实现对遥感影像的快速组织与实时发布,为解决当前遥感影像数据共享问题提供了较好的解决思路。
This paper studies the characteristics of remote sensing data and analyzes application status,combines with LOD ideas and images pyramid model and uses the optimize fragmentary image division algorithm to divide images into several blocks,according to the way of shared directory to organize the fragments.It establishes a Web-based distributed remote sensing image data release framework,achieves the rapid organization and real-time release of remote sensing images,and provides good ideas to solve the problems of sharing remote sensing image data.
