Can we discriminate please between a pier on piers (e.g. made from oak or concrete piers) and a quay with a closed mural/wall? Bigger piers with walls you find rails on small ones not. Even pontons should be signed as those. We can leave that questions up to next saison (nothern hemisphere) where I hope to drag a flock of people to their boats and canoes to mape waterways. scoid 10:56, 3 November 2006 (UTC)

The Isle of Wight has a number of piers, ranging in size from short narrow ones, to one with both a road and a train line on it. This larger one (see picture) I drew as an area, but still tagged it on my local OSM data as manmade=pier, whilst the smaller ones I just tagged the segment as manmade=pier.

Lost in translation

How to tag piers that doesn't fit this description? There are languages that use the same word for pier, warf, quey, breakwater, etc. I have until now not seen a clear definition to tag the warf or the quey, and neither clear definition of these. These pages should also be inter-linked, so that people looking for the one or the other can be guided to the right tag. --Skippern 10:44, 27 August 2009 (UTC)

Yes, it's a mess with different meanings, translations and synonyms. I will try to give a structure to the marine-related pages based on IHO definitions (why reeinvent the wheel), starting on Marine_Mapping with the already suggested structure. Obviously it would make sense to have also an alphabetical index which includes the synonyms. I will take this into account. --HeikoE 11:11, 27 August 2009 (UTC)

Enable routing for pier needs highway tag

If a pier should be usable for routing its seems to be necessary to add a highway tag and not only to be connected.

Why does it have to end on the shoreline?

Why should a pier share a node with the shoreline? Some piers don't stop at the "average maximum water level", which is used to draw the shorlines. Most piers stop at the "expected absolute maximum water level", which is normally further into the land than the shoreline. I don't see any reason (routing, rendering, ...) why it should share a node with the shoreline. --Sanderd17 10:03, 21 September 2012 (BST)

You make a fair point. PeterIto 22:38, 21 September 2012 (BST)
I concur, let's map reality --Kaitu (talk) 16:11, 11 February 2016 (UTC)

Shouldn't we be mapping piers (those elevated on pilings or stilts) as Bridges? And Quays as Shoreline? And Gangways as Bridges? and Floating Docks (Pontoons) as something other than Piers?

Shouldn't we be mapping Piers (those elevated on pilings or stilts) as Bridges? And Quays as Shoreline? And Gangways as Bridges? and Floating Docks (Pontoons) as something other than Piers? For marine navigation this could come in handy for routing purposes. I wonder how OpenSeaMaps contends with these issues?--Fabflockfinder (talk) 16:04, 12 August 2013 (UTC)

The difference between a pier and a bridge seems to be that the bridge has land on both ends while the pier does only on one end. Yet the limitation to the jetty-like definition (docking station for boats) makes this tag unusable for bridges/piers that are meant e.g. as viewpoints. See and or for such a cases. It would be good to drop that requirements and maybe add it as another tag (e.g. jetty=yes). --MomoMilkiway (talk) 18:38, 27 May 2021 (UTC)

Shipping piers

Most piers are T shaped for docking freighters, but these are not given in the illustrations - could lead to errors. Jamesks 09:07, 17 Feb 2017 (UTC)

Seasonal piers?

Having edited OSM for quite some years I have become increasingly aware of how many (especially small, private piers along danish coasts) that really exist only during summer. I've given up on mapping most of what appears to be private piers, but still see other mappers add them. Should we tag them seasonal=*, map or not map them (since they're often hard to keep track of)? --Hjart (talk) 07:40, 1 September 2019 (UTC)

What happens to the structure during winter - is it disassembled and placed in a shed? Ecatmur (talk) 16:02, 30 October 2019 (UTC)
My guess is that they are covered by water in the winter. That can happen with some "fixed", none floating piers. --Adamant1 (talk) 01:35, 2 January 2020 (UTC)

area=yes ???

If it shound be an area we should use area=yes, do we? taginfo has about 87.222 hits in combination with area=yes. So this should be documented. Right? --EinKonstanzer (talk) 18:19, 20 September 2021 (UTC)

Yes, this should be documented, I have added this to the page. Dmgroom (talk)
@Dmgroom: Is area=yes really needed? I cannot imagine a closed way with man_made=pier which is not an area area but, please, proof me wrong. --Skyper (talk) 15:29, 5 March 2023 (UTC)
Imagine four narrow piers joined together in a square pattern. Being narrow each pier is not drawn as a closed way. Dmgroom (talk)
I see. If these are four narrow piers why would you map it as a single closed way instead of four connected open ways? If you need to map it as a single closed way area=no might be an option instead. --Skyper (talk) 14:06, 1 May 2023 (UTC)
Because it could be argued it is in fact [one narrow pier in a square pattern], also imagine a narrow circular pier which was not an area, see links for actual examples mapped by other mappers.Dmgroom (talk) 15:11, 3 May 2023 (UTC)
Thanks, both examples are tagged with area=no. I would say area=yes is the default and not needed and area=no should be used for closed ways which do not represent an area. --Skyper (talk) 11:07, 4 May 2023 (UTC)

Improvement to How to map section

Hello! The section “How to map” mentions to add a highway=* feature to connect the pier to the main road network, but doesn’t specify connecting the highways to ferry routes or terminals, which is important for routing. The text could be updated to clear this up.

I propose changing the two sentences that start with “Lastly,…” to say instead “Lastly, usually due to ferry terminals and routes, create a highway depending on how the pier is modeled. If the pier is modeled as a linear way, add a highway=* tag to the pier and ensure it connects to the main road/pedestrian network. If the pier is modeled as an area, create a separate highway=* feature that connects the ferry terminal/route to the greater road network.” Thanks! --Awiseman (talk) 20:01, 13 January 2022 (UTC)

Ok, I'm going to update the page with this info --Awiseman (talk) 19:52, 26 January 2022 (UTC)

The highway tag isn't required as the primary purpose of a pier is for people to walk on it. (See also railway=platform). Routers should be able deal with such items, even when modelled as a closed polygon.--DaveF63 (talk) 15:35, 27 June 2023 (UTC)


What if the pier looks like a fishbone, with many many parking spaces for boats each with their own little outlines?

Can I just use an outline for the whole pier plus boat parking spaces? Or must I add each little individual boat parking space somehow? And what about the name for the pier, how is that going to get rendered along with the pier? --Jidanni (talk) 09:44, 3 October 2022 (UTC)

As usual in OSM we start with a broader approach and add further details afterwards. I do not see a problem with a fishbone shape. If you want to tag each individual space, we might need some new tags to define it appropriate. Rendering is a different task and up to the rendering machine but if we have designed a clean tagging system it should not be a major issue for the renderer to support it. --Skyper (talk) 14:17, 1 May 2023 (UTC)
