An isthmus is a narrow strip of land with water on both sides that connects two bigger land masses, see e.g. the L'Isthme de Penthièvre, which connects the peninsula of Quiberon with mainland France: https://www.openstreetmap.org/node/2450239624#map=11/47.5485/-3.0755 Promontories, headlands and capes seem to be almost synonymes, see e.g. the definitions by Merriam-Webster: * promontory: (a) a high point of land or rock projecting into a body of water; (b) a prominent mass of land overlooking or projecting into a lowland * headland: a point of usually high land jutting out into a body of water: promontory * cape: a point or extension of land jutting out into water as a peninsula or as a projecting point The difference from a peninsula (from Latin paeninsula = 'almost island') seem to be the connection to the mainland: it is significantly wider in case of a promontory/headland/cape, but an isthmus in case of a peninsula. Merriam-Webster: * peninsula: a portion of land nearly surrounded by water and connected with a larger body by an isthmus See also the diagrams on this web page: http://www.eschooltoday.com/landforms/what-is-a-cape-and-peninsula-landform.html > I would think all of these should come under natural=x, & should be > mapped as they are named: =headland, =cape, =peninsula, =promontory etc etc If promontory, headland and cape is already part of the name, why duplicating it with different tags?

Re: [Tagging] Feature Proposal – RFC – place=peninsula
" I would think all of these should come under natural=x, & should be mapped as they are named: =headland, =cape, =peninsula, =promontory etc etc " +1 That's been my general practice as well. The designations of cape, point, peninsula, headland, etc., are all arbitrary and come from historical usage.

The natural=cape wiki makes reference to See Also natural-isthmus (but the page doesn't exist!) & lists natural=headland (also doesn't exist) as a Possible Tagging Mistake. Why? When I've looked at a few headlands I know, a couple of them are listed as place=locality, name=Indian Head, which, to me, doesn't really ring true? I would think all of these should come under natural=x, & should be mapped as they are named: =headland, =cape, =peninsula, =promontory etc etc Thanks Graeme ___ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging

Re: [Tagging] Feature Proposal – RFC – place=peninsula
> Is there an upper cut-off where things stop being a peninsula? Hmmm ... not really. And it doesn't have to be the same body of water either - the Upper and Lower Peninsula of Michigan State are isolated by the collective waters of the Great Lakes. The Iberian Peninsula in Europe, the Korean Peninsula, Florida, are also quite large. Not to get to fractal, but peninsula can have peninsula. The 'base' which connects also is quite varied, sometimes a river, a piedmont, or the ridge line of a major drainage. Local here, we have Camano Island, which is really a peninsula.

Re: [Tagging] Feature Proposal – RFC – place=peninsula
I would also think natural= is a "nicer" approach :-) Under the list of examples given on the proposal https://wiki.openstreetmap.org/wiki/Proposed_features/Tag:place%3Dpeninsula I was quite surprised to see India listed as a peninsula? https://www.openstreetmap.org/node/4869234021#map=4/17.85/78.18 I guess it is, as it's a (big!) lump of land sticking out into the water, but I have always seen it referred to as the Indian Sub-Continent? Is there an upper cut-off where things stop being a peninsula? Thanks Graeme ___ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
Re: [Tagging] Feature Proposal – RFC – place=peninsula
I would not disagree with the reasoning fur the use of either tag but have used natural=peninsula extensively in my Alaska mapping so I prefer going forward with that one.

A peninsula is a land form, on the other hand, we're also using place=* for islands, islets and continents (as well as oceans and seas), which are also land forms. But i were fine with natural=peninsula too. The main thing for me is that we can agree on one tag. ___ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
