随着信息技术和传感器技术的飞速发展,使得遥感图像的数据量呈几何级数的递增,而传统的利用文件指针来读取文件的方法,只能正确读取2GB以下的数据。针对此种情况,提出了新方法,并分析了其关键技术,用VC++给出了实现的代 码。
The rapid development of information technology and sensor technology has given rise to the geometrically progressive increase of remote sensing data. Aware of the conventional means' incapability to read file data above 2GB exactly, a new reading technique has been proposed,through analysis of its critical techniques, and lists the code segments on the strength of (VC++).
