surfaceTemperature: Estimates Land Surface Temperature from Landsat Data

Description

Surface temperature is estimated using a modified Plank equation considering empirical constants for Landsat images. In addition, this model implements a correction of thermal radiance following to Wukelic et al. (1989).

Usage

surfaceTemperature(thermalband, thermalband2, sat = "auto", LAI, aoi, method = "SC", WeatherStation)

Arguments

thermalband

Satellite thermal band. For L8 this should be band 10.

thermalband2

Second thermal band. Only needed for split window method. For L8 this should be band 11.

sat

"L7" for Landsat 7, "L8" for Landsat 8 or "auto" to guess from filenames

LAI

raster layer with leaf area index. See LAI()

aoi

area of interest to crop images, if waterOptions("autoAoi") == TRUE will look for any object called aoi on .GlobalEnv

method

"SC" for single channel or "SW" for split window algorithm. "SW" is only available for L8

WeatherStation

Weather Station data
