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)

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. Landsat)

• 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)

• RID region id (e.g. R00001) for multi region Satellite objects

• 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

Arguments

files

Path and filename of the Landsat metadata file.

Examples

path <- system.file("extdata", package = "satellite")
files <- list.files(path, pattern = glob2rx("LC08*.TIF"), full.names = TRUE)
