Random Forest Steps in SNAP

Ok i just need to ask some basics because im new to the SNAP application.
So the casual process for any Supervised Classification is:

  1. Resample
  2. Reproject
  3. Create Vector Datas (Water, Buildings, Vegetation…)
  4. Raster - Classification - Supervised Classification - Random Forest

That’s all? or i need to be carefull for some things… or i forgot somethings

Thanks again.

The reprojection step might not be necessary. I made a classification on a S2-MSI without reprojection a few days ago.

When i try to use supervised classification it appears an Error about the dimension sometimes…
