I am doing land cover classification over the whole country of Djibouti.
I am downloading Sentinel 2 images for this purpose. I have realised doing land cover classification over a large area needs downloading several images as I was used to smaller regions prior to this.
My question is, is there a simpler way to do land cover classification over a whole country without downloading several images, doing atmospheric correction (and other preprocessing procedures) where such kind of procedures may be faced with time constraints.
I hear coding may assist but I am not good in this area. Anyone who has had such a similar workload can advise me. I am using QGIS 3.14
