NDVI的定义,NDVI=(NIR-RED)/(NIR+RED),就算是看完这个公式,我相信大多数人仍然不知道它在说什么,那我们就一个参数,一个参数单独拆分出来解释。NIR:Near Infrared 就是近红外的意思。RED 就是红光的意思。 有很多人并不了解光谱的东东,实际上光根据不同的波长进行分类是一个很有意思的事情。其实太阳光照射的...

As shown below,Normalized Difference Vegetation Index (NDVI)uses the NIR and red channels in its formula. Healthy vegetation (chlorophyll) reflects more near-infrared (NIR) and green light compared to other wavelengths. But it absorbs more red and blue light. ...
1)normalized difference vegetation indexNDVI 1.On the basis of Normalized Difference Vegetation Index (NDVI) data with resolution of 1 km of NOAA/AVHRR in 1993 and NDVI data for MODIS in 2000 and 2006,the authors analyzed the NDVI spatial dynamic variations by changing intensive parameters in th...

The normalized difference vegetation index (NDVI) is often used as a marker of surrounding greenness in epidemiological studies aiming to evaluate the health effects of green space in urban settings. However, it is not clear the relationship between built environment characteristics, including green spa...
