Are you meaning the horizontal line half way between Vic and Tas in bass straight? If it is it is the state border between the two not the maritime boarder.
I am currently tidying the existing maritime boarder to correctly render with mgkmap and mapnik using osm rules for maritime boarders. It doesn't seem to need the baseline I was talking about originally. The line around the coast is the 12nm zone that we now can see. http://www.ga.gov.au/oceans/mc_amb-bndrs.jsp http://wiki.openstreetmap.org/wiki/Proposed_features/Maritime_borders If I have made a mistake interpreting it let me know.

Bass Strait seems to have been given over to international waters according to that statement. There are some weird lines around Vic / Tas and the Bass Strait islands at the moment on zoom level 7 which i assume are linked to this converstation.

Which was made redundent by creating shape files from the coastline segments before relations existed, although this is probably still a lot more useful. > The maritime borders are 12nm out to sea from the coastline. See below link. Yes, but coastlines should be much less nodes otherwise you start hitting problems similar to those in the Philippines... _______________________________________________ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
