Add support for taxiways and aprons.

[PlanMan1717]

Runways are good, roads are good, taxiways and aprons, however, are not.

PHTO, Hilo International Airport, Hilo, Hawaii.

Could you go into more detail on what you're seeing vs. what you're expecting to see?

Those tags already do have some rudimentary support in OSM2World, but I'm sure they could look better. As I don't know much about airports, I'd be happy to learn how they could be improved.

I am no OSM expert either, but I can give you my best take on the matter.

Runways and taxiways are both appropriated by <tag k="aeroway" v="taxiway"/> and <tag k="aeroway" v="runway"/>

It should be noted that runways and taxiways are represented by ways or areas, and frequently exist together.

Runways

• Are always represented by the direction they face on a compass.
  • But they do this by lopping off the last digit and rounding.
  • So a runway going west (270 degrees) is runway 07.
• Come in pairs, so...
  • The compliment of a given runway is the runway number subtracted from 36.
• Can have a R or an L.:
  • If there are two parallel runways, a distinction must be made, a suffix, L, indicating "left"; and R for "right".
  • Always from the pilot's perspective.
  • If there are 3 parallel runways (very rare) then the center one is given C for "center".

The structure and composition of a runway:

Runways are multi-thousand feet long strips that frequently land many hundreds of heavy jets in any weather. They are designed to be as informative as possible while not interfering with a planes approach.

This is the part where I insert a disclaimer.

"I am not a pilot; just an enthusiast. Therefore, don't take what I say as complete, thorough, and/or a guide to land a plane... it is just to provide details pertaining to creating a realistic(ish) OSM datapoint."

Reference this diagram:

Taxiways

• Are how planes get from parking to the runway.

• They are referenced by a letter, A - Z.

  • If there are more than 26 taxiways, then start using two letters, "AA", "BE", etc.
  • If there are multiple taxiways that are near each other and do essentially the same thing, use letters and numbers.

• Have a particular line pattern.
