Description

This function calculates the TOA (Top Of Atmosphere) reflectance considering only the image metadata.

Usage

1
calcTOAr(image.DN, sat = "auto", aoi, incidence.rel, MTL)

Arguments

image.DN

raw image in digital numbers

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

solar incidence angle, considering the relief

MTL
