I’m new to this.

I did what most people probably do and added/adjusted footprints of houses in my neighborhood. Great but I soon noticed that there were choices to be made about what did or didn’t get included, what level of detail to go to, etc. and no really obvious source of guidance about that.

Which is probably just as well, because if there were masses of prescriptive guidance about every little thing a new user would get buried. Anyway. I settled on what seemed reasonable to me and fleshed out the neighborhood a bit. Fun.

I’m a private pilot, so I checked out my local airport to see how things looked there. It was really quite good in some respects, if a little out of date. But again since there’s no guidance the previous editors had just made reasonable assumptions and got on with it. I noticed a few taxiway connections were missing (I taxi along them regularly so I know they’re there!) and added them. Then realized that the previous editor had only been adding taxiways that correspond to the painted lines. Reasonable but in reality things are more joined up than that. Food for thought.

So I thought I would check out a large nearby airport. Whoever did this has made a different set of assumptions about what a reasonable level of detail is. Nothing wrong with them, just different.

Then I checked out Chicago O’Hare. Wow. Someone went to town here. Every single parking spot in the parking garage is individually mapped. That seems excessive (and dragged my machine to it’s knees as well). I’m sure some aggregation would be better. Never mind.

Checked out Newark. Much more reasonable level of detail here. But I suppose that depends on what you expect people to use it for. JFK is different again.

It seems like it would good to define use cases and detail levels for this. Not to be prescriptive, just to give editors some kind of framework to consider if it helps organize their work. The wiki does have some information but it’s more about the specifics than overall organization. I expect GIS professionals have a whole framework for this kind of thing but that would be overkill.

I’ll see if I can find anyone interested it working on this. I’m too new around here to figure out how to do that though.
