calcSR: Calculates surface reflectance for L7

In water: Actual Evapotranspiration with Energy Balance Models

Description

Calculates surface reflectance from top of atmosphere radiance using the model developed by Tasumi et al. (2008) and Allen et al. (2007), which considers a band-by-band basis.

Usage

calcSR(image.TOAr, sat = "auto", aoi, incidence.hor, WeatherStation,
  surface.model)

Arguments

image.TOAr	raster stack. top of atmosphere reflectance image
sat	"L7" for Landsat 7, "L8" for Landsat 8 or "auto" to guess from filenames
aoi	area of interest to crop images, if waterOptions("autoAoi") == TRUE will look for any object called aoi on .GlobalEnv
incidence.hor	solar incidence angle, considering plain surface
WeatherStation	Weather Station data
surface.model	rasterStack with DEM, Slope and Aspect. See surface.model()
