convRad2BT: Convert a band's scaled counts to brightness temperature

Description

Convert a band's radiance values to brightness temperature without any kind of atmospheric correction etc.

Usage

# S4 method for Satellite
convRad2BT(x)
# S4 method for RasterStack
convRad2BT(x, k1, k2)
# S4 method for RasterLayer
convRad2BT(x, k1, k2)

Value

If x is a Satellite object, a Satellite object with added converted layers;

if x is a raster::Raster* object, a raster::Raster* object with converted layer(s).

Arguments

x

An object of class Satellite, raster::RasterStack or raster::RasterLayer providing radiance values.

k1, k2

Temperature correction parameters.

Details

The conversion functions are taken from USGS' Landsat 8 Data Users Handbook which is available online at https://www.usgs.gov/landsat-missions/landsat-8-data-users-handbook.

Examples

path <- system.file("extdata", package = "satellite")
files <- list.files(path, pattern = glob2rx("LC08*.TIF"), full.names = TRUE)
sat <- satellite(files)  
sat <- convRad2BT(sat)
