Proposal talk:Aeroway=heliport

Lacking definition

As it is the proposal lacks any definition what a heliport is supposed to be and how a mapper can decide if something is supposed to be tagged aeroway=heliport, aeroway=helipad, aeroway=aerodrome or something entirely different.--Imagico (talk) 17:44, 23 September 2015 (UTC)

I would agree with the above, there is no clear criteria for what this proposed tag should apply to. Helipad is pretty clear, it is the area one lands a helicopter on. I do not know this means in the modified section: "aeroway=helipad - definition clearing and links to aeroway=heliport" I guess my main concern is for the existing aeroway=helipad objects. Are they intended to be changed? --Bgirardot (talk) 17:52, 23 September 2015 (UTC)

These pages should be just completed to make people aware of a heliport tagging - nothing more. --Kocio (talk) 18:19, 23 September 2015 (UTC)

In my proposition criteria should simply be like this:

• if this is not only for helicopters (planes probably), than it's aeroway=aerodrome
• if this is only a landing place for helicopters (without additional infrastructure), then it's aeroway=helipad
• if this is more than a landing place for helicopters (with additional infrastructure), then it's aeroway=heliport

Is it clear now? I thought "Aerodrome (AE: airport) for helicopters" definition covers it good enough. --Kocio (talk) 18:17, 23 September 2015 (UTC)

That helps - So my understanding is that for some places, there would be both aeroway=helipad and a larger area enclosing that, aeroway=heliport. I would think there would be no way to have a heliport without at least one area or node marked helipad. Much like we don't have an aerodrome without a runway. And, if I understand things correctly, a confusing statement to me "definition clearing" means "definition clarification", making the definition of helipad more clear. "clearing" in english means "removing" or "wiping away" or "empty" partly why I was not sure how this affects the existing helipads. --Bgirardot (talk) 18:34, 23 September 2015 (UTC)

You're right, I meant clarification, of course. I'm not sure if the heliports always have at least one helipad - maybe some of them can have blurry area for landing, but probably most of them look like you've just described it. --Kocio (talk) 18:43, 23 September 2015 (UTC)

Yes, these criteria make sense. You could clarify 'additional infrastructure' somewhat further (i.e. more than just landing aids) --Imagico (talk) 18:48, 23 September 2015 (UTC)

Is this definition proper or you'd like to change anything? --Kocio (talk) 20:13, 23 September 2015 (UTC)

I imagine the additional infrastructure is hangars, passenger terminals, fuel service, control tower, passenger parking, fire/crash response, and/or taxiways to the "runway" (the one big named&numbered helipad runway) for large helicopters. Javbw (talk) 00:44, 24 September 2015 (UTC)

Sure, I just want to know how should the definition look like. In general I don't like putting all the possible or typical things there, because they are not essential, which causes heavy confusion in some cases (it's like defining a bicycle to have 2 wheels, which is typical, but makes a problem when trying to tag 3-wheeled ones). We could of course make it additional list named "typical infrastructure" - or just refer to the aerodrome page. --Kocio (talk) 10:29, 24 September 2015 (UTC)
