Proposal talk:Tag:natural=baseline

The tag sounds like a boundary rather than low tide line

There is already an approved tag for the administrative "baseline" used to calculate national borders: boundary=maritime + boundary_type=baseline, and the baseline isn't a natural feature, but a political boundary.

If you want to map the average low tide line, such as the "mean low water springs" or "mean low water neaps", this might be under natural=* with a value like natural=low_tide_line or natural=mean_low_water_springs or natural=mean_low_water_line or similar. But the current proposal for natural=baseline isn't a good idea. --Jeisenbe (talk) 01:00, 3 September 2019 (UTC)

The idea was to tag the natural low tide line, which is the basis for the maritime boundary. This boundary can be normal or straight, the former being the natural low tide line, and the later is used for river mouths and some bays. The natural=baseline just felt right, but natural=low_tide_line works fine too. --Iagocasabiell (talk) 10:34, 5 September 2019 (UTC)

In archipelagos the baseline is very differnet than the low tide line, and the same thing happens with some bays, where the political baseline cuts across the mouth of the bay, rather than following the low tide line, so I think it would be important to avoid confusion. --Jeisenbe (talk) 14:00, 5 September 2019 (UTC)

Ok, I think these other proposals will avoid confusion:

• Proposed_features/Tide_lines
• Proposed_features/Tag:natural=mean_low_water_springs
• Proposed_features/Tag:natural=mean_high_water_neaps
• Proposed_features/Tag:natural=mean_low_water_neaps

Thanks, Proposed_features/Tag:natural=mean_low_water_springs should be clear. It's not a very common term, but it should be known by people who would be interested in mapping such things. But are you personally interested in mapping the high water neaps and low water neaps? How do you plan to do this? Unless there was some official info available to import, I would think it would be quite hard to precisely map all 4 different lines, especiall the neaps, which are more a statistical property. --Jeisenbe (talk) 03:29, 6 September 2019 (UTC)
