In serbinsh/R-FieldSpectra: Functions for processing field spectroscopy data. Current supported instruments include ADS FieldSpec, Spectral Evolution, and Spectra Vista Corporation

Convolve field spectral observations to airborne/satellite spectral bands/channels.

Description

Convolve field spectral observations to airborne/satellite spectral bands/channels.

Usage

convolve.spectra(
  field.spectra = NULL,
  start.wave = NULL,
  end.wave = NULL,
  sensor = NULL,
  year = NULL,
  spc = NULL
)

Arguments

field.spectra	Input field spectra. If a single spectra then the format can be either column or row major with the wavelengths either a column of data or the column headers. If multiple (i.e. a matrix of data) the input should be in row major format with the column headers as wavelength numbers. See examples below.
start.wave	Starting wavelength of field spectra
end.wave	ending wavelength of field spectra
sensor	The sensor (e.g. "AVIRIS", "Landsat 5", "Landsat 7", "MODIS"). Current options are: "AVIRIS" More to come in the future
year	[Optional] E.g. year=2011. If the AVIRIS sensor is selected this allows the user to select a specific spectral calibration based on the year of data aquisition. Defaults to 2011.
spc	[Optional] Option to use custom spectral calibration information. Format: band number, center wavelength, FWHM. NOT YET IMPLEMENTED
output.dir	[Optional] Directory to output the convolved spectral data. If not set the results are only pasesd back to the working environment

Value

output.spectra Returns a matrix of convolved spectra
