摘要
本文首先介绍了高光谱植被指数VIUPD,然后利用ENVI4.0对AVIRIS数据进行了预处理,并利用处理后的数据在Matlab7.0上实现了植被指数VIUPD,最后通过ENVI4.0进行了结果显示。结果表明,VIUPD比NDVI和EVI对于植被的变化更敏感。
This paper described the hyperspectral vegetation index VIUPD at the first,and then introduced the data processing using AVIRIS data and ENVI 4.0 software,as well as the AVIRIS data and Matlab 7.0 to perform the hyperspectral vegetation index VIUPD.The results showed that the VIUPD reflects vegetation and vegetation activity more sensitively than the NDVI and EVI.
