Often we encounter multi-spectral and hyper-spectral sensors offering multiple NIR bands. For instance, the WorldView 3 sensor has 8 MS bands, out of them, two bands fall within NIR region.
Near-IR1: 770 - 895 nm
Near-IR2: 860 - 1040 nm
In case of hyper-spectral imagery, there are number of NIR bands with narrower bandwidth. So, in terms of NIR spectral range, there are many choices which apparently makes it hard to select suitable NIR band to compute spectral indices like NDVI.
What are the conceptual and theoretical basis to select optimal NIR spectral range to compute NDVI?
