spliceCorrection: Splice correction of a spectral matrix acquired with an ASD spectrometer

Description

Corrects steps in an input spectral matrix by linear interpolation of the values of the edges of the middle sensor

Usage

spliceCorrection(X,wav,splice=c(1000,1830),interpol.bands=10)

Arguments

X

numeric data.frame, matrix or vector to transform

wav

numeric vector with band positions

splice

numeric vector of the two positions of the splices, default = c(1000,1830) corresponding to the splices of the ASD FieldSpec Pro spectrometer.

interpol.bands

number of interpolation bands

Value

a matrix with the splice corrected data

Details

Spectra acquired with an ASD FieldSpec Pro spectroradiometer usually exhibit steps at the splice of the three built-in sensors, positioned at 1000 nm (end of VNIR detector) and 1830 nm (end of SWIR1 detector).
