pr_create_swir: pr_create_swir

In lbusett/prismaread: Import PRISMA L1/L2 hyperspectral data and convert them to a more user friendly format

Description

helper function used to process and save the SWIR data cube

Usage

pr_create_swir(
  f,
  proc_lev,
  source,
  out_file_swir,
  out_format,
  base_georef,
  fill_gaps,
  wl_swir,
  order_swir,
  fwhm_swir,
  apply_errmatrix,
  ERR_MATRIX,
  selbands_swir = NULL,
  in_L2_file = NULL
)

Arguments

f	input data he5 from caller
proc_lev	'character' Processing level (e.g., "1", "2B") - passed by caller
source	'character' ["HC0" | "HRC"], Considered Data Cub, Default: 'HCO'
out_file_swir	output file name for SWIR
out_format	'character“ ["GTiff" | "ENVI"], Output format, Default: 'GTiff'
base_georef	'logical' if TRUE, apply base georeferencing on L1, L2B/C data, using the "Georeference from input GLT" procedure explained here: https://www.harrisgeospatial.com/docs/backgroundgltbowtiecorrection.html, Default: TRUE
fill_gaps	'logical' if TRUE, when georeferencing on L1, L2B/C data, substitute missing values with results of a 3x3 focal filter on the georeferenced data, Default: FALSE
wl_swir	passed by caller - array of PRISMA SWIR wavelengths
order_swir	passed by caller - ordering of array of PRISMA SWIR wavelengths
fwhm_swir	passed by caller - array of PRISMA SWIR fwhms
apply_errmatrix	'logical' if TRUE, set pixels with values above 0 in the SATERR_MATRIX data cube (for L1) or ERRMATRIX cube (for L2) to NA, Default: FALSE
ERR_MATRIX	'logical' if TRUE, also save the SATURATION ERROR MATRIX Data, Default: FALSE SATURATION ERROR MATRIX is coded as: 0=pixel ok; 1=DEFECTIVE PIXEL from KDP 2= Pixel in saturation. 3= Pixel with lower radiometric accuracy, due to coregistration effects. 4= Pixel becomes NaN or Inf during processing.
selbands_swir	'numeric array' containing wavelengths (in nanometers) of bands that should be extracted from the SWIR data cube. If not NULL, only the bands with wavelengths closest to these values are extracted, Default: NULL
in_L2_file	'character' full path of an L2B/C file to be used to extract georeferencing info and angles for a corresponding L1 file. If not NULL, and 'in_file' is a L1 file, the LAT and LON fields used for bowtie georeferencing are taken from the L2 file instead than from the L1 file. The ANGLES data are also retrieved from the L2 file if requested.

Value

the function is called for its side effects
