IDL中计算归一化植被指数需要用到的归一化植被指数计算程序-IDL to calculate the normalized difference vegetation index need to use the normalized difference vegetation index calculation program

归一化植被指数 NDVI=(NIR-R)/(NIR+R)，或两个波段反射率的计算。 本程序可以用于计算植被归一化指数，mfc界面(Normalized vegetation index NDVI= (NIR-R) / (NIR+R), or two band reflectivity calculation.)
