[Therion] Point Depth

[Torsten Schnitter]

Hi

I don't know any map with both marks in it as I can remember.

But a possible use for both within a map may be given.
E.g. if you have a cave with a depth of 10m at the entrance at an altitude of
100m above sealevel.
A km inside you may have also a depth of 10m but the altitude may be 120m or
just 80m (whatever).
It is possible the aquifier to be not at the same level all the time.
So may be there is a use for both markers.

Thanks for help.

best,
Torsten
