imageIndices {soilassessment}

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
