compMetaLandsat: Get calibration information from Landsat 8 standard level 1B/T filename

Description

The function scans a Lansat metadata file for various calibration and orbit coefficients as well as some sensor specific data.

Usage

compMetaLandsat(files)

Arguments

files

Path and filename of the Landsat metadata file.

Value

• data.frame containing the following information for each band/layer:
  • DATE date (e.g. 2013-07-07)
  • SID sensor id (e.g. LC8)
  • SENSOR sensor name (e.g. Landsat 8)
  • SGRP sensor group (e.g. Landast)
  • BID band id (e.g. 7)
  • BCDE band code (5 digit standard name, e.g B001n)
  • SRES spatial resolution of the sensor band (e.g. 30 for 30 m x 30m)
  • TYPE type of the sensor band regarding wavelength (e.g. VIS)
  • SPECTRUM spectral range regarding radiation source (e.g. solar)
  • CALIB type of applied calibration (e.g. SC for scaled counts)
  • RADA addtition coefficient for radiance conversion
  • RADM multiplication coefficient for radiance conversion
  • REFA addtition coefficient for reflectance conversion
  • REFM multiplication coefficient for reflectance conversion
  • BTK1 brightness temperature correction parameter
  • BTK2 brightness temperature correction parameter
  • SZEN sun zenith angle
  • SAZM sun azimuth angle
  • SELV sun elevation angle
  • ESD earth-sun distance (AU)
  • LMIN Minimum wavelength of the band (micrometer)
  • LMAX Maximum wavelength of the band (micrometer)
  • RADMIN Minimum radiance recorded by the band
  • RADMAX Maximum radiance recorded by the band
  • REFMIN Minimum reflectance recorded by the band
  • REFMAX Maximum reflectance recorded by the band
  • LNBR Layer number from 1 to n layers
  • LAYER Layer name
  • FILE Filepath of the data file
  • METAFILE Filepath of the metadata file
