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

## S3 method for class 'Satellite':
convRad2BT(x)
## S3 method for class 'RasterStack':
convRad2BT(x, k1, k2)
## S3 method for class 'RasterLayer':
convRad2BT(x, k1, k2)

Arguments

x

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

k1,k2

Temperature correction parameters.

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).

Details

The conversion functions are taken from USGS' Landsat 8 manual which is available online at http://landsat.usgs.gov/Landsat8_Using_Product.php.
