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 ...

Two decades of normalized difference vegetation index changes in South America: identifying the imprint of global change. International Journal of Remote Sensing 25:2793-2806.Paruelo JM, Garbulsky MF, Guerschman JP, Jobbagy EG. 2004. Two decades of normalized difference vegetation index changes ...
Crops with yellow canopies have higher reflection in spectrum 0.59–0.63μm and 0.69–0.73μm.Normalized difference of yellow vegetation index (NDYVI) was proposed by using yellow, red-edge1 and NIR band of Gaofen-6 images.NDYVI achieved great performance in discriminating rapeseed with winter wh...
Normalized difference vegetation index NDVI is derived from the red (0.58–0.68 μm) and near-infrared (0.73–1.10 μm) reflectance ratio, based on the fact that chlorophyll absorbs red whereas the mesophyll leaf structure scatters NIR (Reed et al., 1994).NDVI=NIR−REDNIR+REDwhere NIR is...

We used the normalized difference vegetation index (NDVI) as a proxy for NPP. Because of the negative biases due to sensor degradation of MODIS Terra62, NDVI estimations were exclusively based on MODIS Aqua product MYD13Q1 with a horizontal resolution of 250 m × 250 m. Cloud contaminatio...
