[OSM-talk-be] Maritime boundary

[Sander Deryckere]

Hi all,

Just heard Bart Tommelein on De Ideale Wereld this evening, state secretary
of the north sea (amongst other things). There he said that the north sea
is a pure federal responsibility, but the beach is a regional (thus
Flemish) responsibility. However, the boundary isn't the high water line
(which we tag with natural=coastline), but the official boundary is the low
water line (I assume it's the average low water line here, though it could
also be the most extreme low water line).

I guess, ideally, this should be reflected in our data, where we tag the
intermediate section as tidal too.

Now, the only thing we're missing is actual high and low water data :)

So if anyone knows about open, high position datasets that contains the
tidal regions, that would be great. Else we might try to split it with
estimated data.

Regards,
Sander
