Sooooo... makes no sense that it ISN'T foot for foot, meter for meter.
Yeah the problem here is that we dont really know distances nor the borders. :-/
So while two landscape objects distance is abstract ... another can easily be exact.
Imagine it as if you were taking map of any state, then you cut off all those empty space between cities and squeeze it together ...
There is no exact formula, sometimes you lost mile of forest, sometimes you loose thousand miles.
Obviously distances will be messed bcs nobody will know if this cliff is suppose to be next to the grove or miles away.
