Calculates surface reflectance for L7

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

1
2
calcSR(image.TOAr, sat = "auto", ESPA = FALSE, 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

ESPA

Logical. If TRUE will look for espa.usgs.gov related products on working folder

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()
