读取TM波段3和波段4的图像，计算归一化植被指数NDVI，并用NDVI处理单波段图像，突出显示遥感影像的植被部分（输出后的图像上高亮的部分是植被区域）-Band 3 and band 4 images of a TM image are read and NDVI computed. Then a single band image is processed with the NDVI leading to the vegetation regions in the remote sensed

自己写的遥感小程序，基于GDL，能读取浏览遥感影像，显示波段信息。能读取雷达数据，图像处理，直方图等-Write their own remote sensing program, based GDL can read browse remote sensing images show band information. Be able to read the radar data, image processing, histogram

MFCGPS用来根据卫星星历计算任意时刻卫星在WGS84坐标系下的坐标。Foudation of surveying adjustment 用来计算摄影测量中影像外方位元素。Linklists是C++的动态链表，支持任意数据结构，Foudation of Geodesy 是一个用来进行高斯坐标和地理坐标相互转换的程序。GDAL用来读取遥感影像数据，设计界面和ENVI软件相似-MFCGPS any moment of the satellite coordinates in WGS84 coord
