Hi guys.

I have some questions for you. I've seeing a lot of people using sentinel 2A images without atmospheric correction because they say _MSIL2A products are already corrected.

However, it's not very clear.

I'm doing tests with Sentinel images, but soon I'll be working with aerial images from drones. Those will have to be corrected too? Because if so, it would delay my work a bit since I was planning to use Agisoft Metashape to produce orthophotos and then use a GIS software to create image classification.

Does anyone have a better methodology for that? By the way, I forgot to say that the work is related to precision agriculture.

Thanks!
