For example on wikipedia for Switzerland it says the country has an area of 41,285 km². Does this take into account that a lot of that area is actually angled at a steep inclination, thus the actual surface area is in effect larger than what you would expect when looking onto a map in satellite view?
Fractals are self-replicating while surface area or coastline of a country are inherently finite. You could very accurately measure the surface area, but there’s no reason to do that.
