Working with two or more S2 data

Dear all,

I’d like to know how to obtain a S2 image which represent the difference between two S2 data in input. I want to know how to do that because because I need to improve my Supervised/Unsupervised classification.

Thank you so much.


You need to resample both to a common resolution, afterwards you can do a collocation of both products. Then you can do Band Maths between the bands. You can drop the collocation if both products have the same size and cover the same region.
