In the viewfinder_1 data there is a "ghost-hill" in my area. The hill does
not exist in real-life.

Even in the low-resolution viewfinder_3 data there is no hill - correct.

The Copernicus data also does not have the "ghost-hill", but also the high
resolution.

So, IMHO the Copernicus data has a better quality compared to the viewfinder
data.
