[PROJ] Greek geoid model 2023

[Javier Jimenez Shaw]

Hi Nikos

Thanks for your answer.
Yes, more digging would be really appreciated. Every country and agency
works different... and also they change along time.

In Greece there is a vertical CRS  in EPSG, "Piraeus-heigh"
https://epsg.org/crs_5716/Piraeus-height.html

BTW, I do not know that do you mean with epsg:27000 (there is no such a
crs).

Cheers
Javier.
