Sentinel images have very good resolution and makes it obvious that they are huge in size. Since I didn’t want to waste all day preparing them for my research, I decided to write this code which runs all night and gives a nice image-set in following morning.

In this post let me go through the contents inside a level 1 image archive when you download one. Continue reading
