Archeological Sites

Yes! Multiple folks have used the normalized difference vegetation index (NDVI) to look for signs of archaeological sites based on plant growth patterns.

These folks used SkySat in Rome: https://www.mdpi.com/2072-4292/14/4/959/htm

These folks used NDVI from RapidEye in Egypt: https://www.sciencedirect.com/science/article/abs/pii/S2352409X17300561?via%3Dihub

And these folks used PlanetScope NDVI and some other indices in Romania:https://www.mdpi.com/2072-4292/12/12/1975/htm 

Has anyone looked at nearshore, submerged archaeological or historical sites such as shipwrecks?
