Adding amenity=ferry_terminal icon

[kocio-pl]

Resolves #869.

Rendered like bus stop - z=16:

z>=17 (with osmic icon):

[kocio-pl]

Edited version, based on osmic with top inspired by MapQuest Open icon (both are too solid and look rather like bollard for me):

I don't think there is a gain from adding a large specific symbol for this purpose. The meaning is perfectly clear with just a generic square symbol which uses less space and adds less clutter to the map.

[matkoniecz]

Yes, especially that symbol is not really recognisable. Generic square seems much better.

[kocio-pl]

Hm, you may be right. However I'd like to hear if there are some counterexamples, where just the dot with label would be suboptimal choice maybe?

[matthijsmelissen]

At larger terminals, such as here, it might not always be immediately clear which building is the ferry terminal.

[kocio-pl]

So maybe we should show this icon just for areas? Or maybe push it even deeper into z18+ or z19+?

[ximex]

the icon itself looks good.

[matthijsmelissen]

Is is not possible to come up with a simpler symbol for 'ship'? The 'terminal' concept will be clear enough from the ship, I think.

[kocio-pl]

Any ideas are welcome. How should it look like?

I can also split this PR into generic blue square part, which is not controversial, and we can add the icon later, once there is one drawn and approved.

[matkoniecz]

I think that splitting is a good idea.

[pnorman]

Not sure how well it works - it can't always be distinguished from a bus stop

Remember, the marked points are not on the water's edge.

See for example, Tsawwassen. Now, this should probably be an area, but the centroid of the area isn't going to be at the coastline either.

Sidney International is an area, as are Swartz Bay and Langdale.

A ferry icon is useful at lower zooms to show where the terminal is, but at high zooms its pretty eident where the road meets the water. If we wanted an icon there, we should do it based on where the lines touch, not ferry terminals, which are different.

[kocio-pl]

I guess the best choice for terminal icon could be something like what we will shortly use for the ford: just the water and the arrows for showing there is a way over it. However the question is if we want to distinguish those icons, and if yes - in what way should they be different?

[kocio-pl]

What about simpler shape like this:

[matkoniecz]

How it works for places from #1673 (comment) ?

[kocio-pl]

Sidney:

Swartz Bay:

Langdale:

Tsawwassen node is overcrowded with tags (ferry_terminal+locality+traffic_signals), so not suitable for testing this icon.

[kocio-pl]

Maybe we should use the aeroway color for ferry terminal areas too. I guess this might be even used for all the transport terminals (like bus stations).

[sabas]

Rendering the area could be useful.
Should the single berthing points inside the terminal be tagged differently?

@sabas From what I understand on a complex facility amenity=ferry_terminal should be the whole area (buildings, parking spaces), This extends the meaning ferry_terminal a bit but in 2007 there was not so much hindsight (http://wiki.openstreetmap.org/wiki/Talk:Proposed_features/Ferry_Terminal)

EDIT: mooring=ferry is not defined for nodes. So the usual approach seems to be to just end the ferry route on a pier and optionally mark the pier with mooring=ferry.

[jojo4u]

@kocio-pl I improved Tsawwassen.
The other examples suffer from "too much highway=service", something I already fixed on Tsawwassen and will be on Swartz Bay (https://www.openstreetmap.org/note/393069)

[kocio-pl]

First I will have to learn how to tag the airport, then find out what parts ferry terminal consists of, and in the end try to find some analogies. It would be also good to study bus and railway station - or maybe also other transportation stations, to be as universal as possible. However I'm not into transportation too much and try to do few other things, so the help would be welcome.

I just thought it would be dead easy task... =}

[matkoniecz]

Unfortunately in current state it is not ready for merge and it seems unlikely to change in the near future - so I will close it for now.

Updated/new PRs solving this problem are welcomed!

Almost everything is harder than it seems before starting it.

[kocio-pl]

Sure, currently I plan to start with defining airport/heliport/ferry(port) as a similar big areas.
