This tutorial is about the image conversion to Radiance at the Sensor’s Aperture or to Top Of Atmosphere (TOA) Reflectance. It is assumed that one has the basic knowledge of SCP and Basic Tutorials.
SCP includes several tools for preprocessing images such as Landsat, Sentinel-2, Sentinel-3. Using satellite images from various sources could require the preprocessing and radiometric correction.
Usually, remote sensing images are delivered as calibrated Digital Numbers (DN), and the conversion to radiance or reflectance can be performed through parameters that are provided with the image.
This tutorials aims to describe how to perform the conversion to TOA reflectance of remote sensing images. The calculation can be performed for all the bands at once in Band calc, knowing the required parameters.
Following the video of this tutorial.
