Introduction to ARCSI for Generating Analysis Ready Data for Landsat and Sentinel-2

The following tutorial provides an introduction to analysis ready data (ARD) and atmospheric correction using ARCSI. The main datasets used for the tutorial are some Landsat 5 scenes, these are smaller in file size and therefore quicker to download. However, Sentinel-2 is also addressed and the modifications to the Landsat 5 commands provided as examples. […]
