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, sat = "auto", LAI, aoi, WeatherStation)
Arguments
thermalband
Satellite thermal band
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
WeatherStation
Weather Station data
