NDVI程序
- 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
avhrr_ndvi_classification
- NDVI计算的IDL程序，可以用来学习遥感数据的操作-NDVI calculated IDL procedures, can be used to study the operation of remote sensing data
NDVI_
- 该程序实现基于野外测站数据计算NDVI值 要使用该程序，需在E盘根目录下新建NDVI文件夹，然后再NDVI文件夹内新建filepath文件夹 接收在filepath文件夹内新建file.txt文本文件 使用规则，将数据全部拷贝进NDVI文件夹，然后再file.txt文本内输入待计算的文件名，文件名之间以空格隔开 1.txt 2.txt 3.txt 处理文本数据，计算NDVI值，文本格式应该为(下面是前三行的样例) asd 650 3 77
hjndvinew
- IDL编写，对环境卫星进行辐射定标并计算NDVI值。程序设计，1、影像分块，在处理大数据时特别有用；2、XML读取，IDL提供了方便的读写XML的方法；3、日期转儒略日算法；4、表观反射率计算方法；5、字符串处理技巧等。 -IDL to prepare for environmental satellite radiometric calibration and calculate NDVI values. Program design, an image block is particul
fcmax_getmean_vimath_clip_resize
- 求长时间序列求年最大及月平均植被覆盖度FC、NDVI；计算各种植被指数NDVI、RVI、SAVI、DVI等；裁剪遥感影像的IDL批处理；重采样影像的IDL批处理-get the max value of the NDVI or FC and so on
