I didn't know about the practice of mapping the coastline along the baseline, AFAIK we don't map the baseline, only their 12nm offset (maritime borders) Vice versa, the practice is mapping the baseline along the coastline. But I think this is no a good idea, because baseline extend up a bit

By default baselines match with mean low water spring, meanwhile natural=coastline is tagged at mean high water spring. It would be good define some rules related to maritime boundaries don't agree with UNCLOS, .e.g. peruvian boundary extends up 200 miles away the coastline.

I don't know the Australian baseline, this is only an example. Sometimes the countries define a straight baseline that close a bay. Of course, Andrew have the freedoom to use, e.g. the tag description=* to do the mentioned difference. > No, it is not a political issue, the position of the base

An exact limit between the open ocean and a sheltered coast is too arbitrary as natural feature. It seems a political issue. You can use boundary=maritime + border_type=baseline for excluding internal waters from the open ocean, according of laws of the country. Check the article https://en.wik

I've learned a lot from the comments here, based on others comments I think the solution to my issue is to use a tag like like coastline=pelagic (from wikipedia "A pelagic coast refers to a coast which fronts the open ocean, as opposed to a more sheltered coast in a gulf or bay.") on the oceanic co

No, I just tagged the edge of the bay as natural=coastline because this is the top of the tidal range. Even being more rigorous the natural=coastline must be shifted far away towards west of current position. The lower part of Georges River is a typical ria: an unglaciated valley submerged into

Initially I was concerned that by changing the tagging from natural=water, water=bay to natural=bay that the whole bay would be rendered as land since that's what the wiki suggests. I now see that the same user changed the edges of the bay to be natural=coastline to prevent this. I'm agree now tha

I don't think it does to be too fussy about what is 'river' and what is 'sea' and what is 'estuary'. Near where I live, a hydrologist would classify the Hudson River as 'estuary' as far as http://www.openstreetmap.org/way/90929525 because it has a measurable tide right up to that point. Neverthele
