I am planning to carry out LULC map using Sentinel 2 image.
However, I have few queries
- I am going to use sentinel 2 L2A. Do I need to calibrate the image radiometrically by applying atmospheric correction?
- Which calibrated image should I use for my above project , ToA OR BoA?
- The proposed area is a mountainous region, is it possible to apply topographical correction in SNAP toolbox?
Any technical advice or documents related to my question is much appreciated
