Proper feature of Airport taxiways and aprons

[lucas...@gmail.com]

What is the preferred method of drawing airport taxiways and aprons. Should the primary category be "Tarmac" and additional categories be "airport"? Or should the primary category be "Airport Ground/Buildings" and the additional category be "Tarmac". Tarmac as the primary looks better, IMHO, as the darker gray stands out above the lighter gray of the airport polygons.

There's a similar discussion going on about hydrologic (seach on
"tributary") features. My guess is that there's an international body
that controls feature names associated with airports.

"Tarmac" is properly a type of road surface. Not all airport ramps
and aprons are paved with tarmac. Tarmac feature in GMM also shows an
airplane icon, which can get the airport feature busy with icons when
airstrip is also used.

I do not agree with this line of reasoning. We should focus on
creating good data, and not be hindered by the current rendering
scheme used by Maps/Map Maker. The rendering scheme can always be
changed in the future, and if things aren't rendered well, that's a
separate issue we should bug the Map Maker team about.

Thanks Prateek. You explained it pretty well :-)

I'm not sure that the original question has been answered:
"What is the preferred method of drawing airport taxiways and aprons?"

I agree we shouldn't depend on a particular representational
implementation, which can change. But the question of what
constitutes "good data" is still open.

Hey Rich,
Sorry about that. I see that there are multiple questions here. Let
me get to them one by one.

Q. Why should we mark Taxiways/Aprons as Tarmac when in reality some
of these are made up of concrete?

A. Tarmac is a term generally used to refer to Taxiways and Aprons
even though some of those may have been built by concrete. Tarmac
pavements on the other hand refers to the apron/taxiways made
completely by Tarmac material. So, Tarmac in Map Maker refers
specifically to the airport taxiways/aprons. Hence the airplane
icon :) But here's where you do have a valid point about Tarmac's
icons populating the airport when Airstrip comes into picture. You can
post this on the Issue Tracker as a feature enhancement precisely
stating about removing airplane icon for Tarmac.

Q. Now comes the bigger question whether Tarmac should be used as
Primary category or as Additional category? And which is the correct
approach and why?

A. If a specific category is available as primary category, then we
should use it for marking the feature. However, if we want to
elaborate an existing primary category, then we should do so using
additional ones. May be the following example will help clarify this:
We don't any primary category for marking abbeys. So in such case, we
encourage mappers to use Primary category as "Monastery" and
additional category as "Abbey". As far as Tarmacs are concerned, we
have it specifically to mark Airport Taxiways/Aprons. So, we might as
well not want to include any additional category for this.

So, Lucas is correct in using "Tarmac" as the primary category. But
as Prateek suggested, the approach shouldn't be biased on the current
rendering scheme(including icons as explained earlier)

Please let me know if you have any further doubts. Also, thanks for
bringing this to my attention, Rich :)

Map Maker Guide

Thanks for the clarifications!

These threads make me happy.  Rich, as always, thanks for your consistent thoughtfulness and presence here.  Prateek, thank you for disagreeing respectfully (and with the answer, not the person).  Lucas, thank you for returning to thank the folks who replied to you (I always feel bad when Map Maker users post detailed replies and don't get any appreciation in return).  And lastly, even though I work with Map Maker Guide and am obviously biased, I still want to give MMG a shoutout for his dedication to this community. :)
