A function for developing remote sensing indices for soil assessment

Description

The function determines commonly used remote sensing indices with relationship with soil surface or vegetation cover characteristics.

Usage

imageIndices(blue, green,red,nir,swir1,swir2,index)

Arguments

blue	blue image band with wavelength range: 0.452-0.512 µm
green	green image band with wavelength range: 0.533-0.59 µm
red	red image band with wavelength range: 0.636-0.673 µm
nir	NIR image band with wavelength range: 0.851-0.879 µm
swir1	SWIR image band with wavelength range: 1.566-1.651 µm
swir2	SWIR image band with wavelength range: 2.107-2.294 µm
index	index from combination of image bands such as NDVI, SAVI, SI, etc. The default is NDVI.

Details

The indices are based on multispectral bands: blue, green, red, NIR(near infrared), SWIR1 (short-wave infrared1) and SWIR2(short-wave infrared2)

Value

dimensionless remote sensing index
