Map altitude to elevation?

[sannegovaert]

I notice we have altitude in the source data. Is that something we could map to elevation?

It looks like this has a too big error.
For example, for the first line row altitude is 52 m, while it is on the DIjleberg (51.01191329956055,4.51769495010376) which should be about 12-13 m.a.s.?
@b-dhondt Do you know?

@sannegovaert : no, I don't. In geopunt, I find a height of about 9 metres for this point.

There are some different reference systems used across Europe (Belgium: TAW). Maybe this is a different, local system (Danish?)? Still, I would find this a big difference.
