遥感卫星影像植被指数

来源:本站   发布时间: 2020-08-03 12:10:08   浏览:1502次  字号: [大] [中] [小]

NDVI:Normalized Difference Vegetation Index,归一化植被指数,从中文名这个“归一化”咱们初步就可以知道它的值范围[-1,1],所以大兄弟,值都在-100了,检查一下数据吧,但也不一定错哈,这种情况我之后会在视频里面说

 

 

再者它是一种植被指数,植被指数它又是啥,它是根据植被的光谱特性,将卫星可见光和近红外波段进行组合,形成了各种植被指数,也就是说肯定不止一种啦,比如多光谱影像中常见的比值植被指数、差值植被指数、归一化差值植被指数、抗大气影响植被指数......

 

随着高光谱遥感技术的发展,遥感仪器的波谱分辨率得到显著提高,越来越多地能够很好反映植物色素含量、水含量、叶片细胞结构等植物信息的植被指数已被发现,不光能反映植被整体状态,还可以局部反应细小的变化

 

啥叫多光谱、高光谱,简单粗暴去区分,高光谱波段多通道窄,比如Hyperion有233~309个波段,而多光谱波段少通道宽,比如ETM+,只有8个波段
