Hi Maria and welcome,
A Pov unit is whatever you want it to mean :)
It has no relation to real life units so it can be one meter, one kilometre one
centimetre or even a foot, yard or mile.
There is a problem if you mix very small and large distances so a scale model of
the solar system is a no-no.
If you are using a heightfield then the image fits into a 1 by 1 by 1 cube. So
scale the X-Y axis's by the image resolution and the z axis by the desired
height.
