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
incidence.rel
solar incidence angle, considering the relief
MTL
Landsat Metadata File
