I'm new to using satellite images. I'm using Landsat images from USGS (Level 1 data), so terrain-corrected. I want to manually delineate different forest classes using false color composites.
Do these satellite images need to be pre-processed prior to doing this?
I won't be doing any calculations and I don't need pixel values to show reflectance or radiance.
I'm simply wondering whether the images not being atmospherically corrected for will impact their visual look?
I don't want to do all this work if it isn't actually necessary for my purposes, so I'm wondering if someone can help me with this.
