针对遥感影像海量数据存储问题，提出了一种基于内存映射的指定块数据快速读取方法，并通过OpenGL对ENVI标准格式的遥感影像海量数据快速读取予以验证。实验结果表明，基于内存映射的方式能有效地解决遥感影像海量数据指定内容的快速读取问题。论文还对内存映射的原理以及基于OpenGL显示的ENVI标准格式遥感影像数据读取程序实现细节进行了描述。

In the light of problems about the large remote sensing image data storage, a method based on memory map- ping to read the specified block data fastly is proposed. That the massive data of remote sensing images on the ENVI standard format can be quickly read by this mehod is verified through OpenGL. The experimental results show that the mehod based on memory mapping can effectively solve the problem of large data specified content fast reading problems. The memory mapping principle and the read program implementation details which based on OpenGL display ENVI standard format remote sensing image data are described.
