Hello, in the search for POI, I searched Orlando International Airport but it does not appear in navigator, yet well encoded in OpenStreetMap (https://www.openstreetmap.org/relation/1144866), why?

tomas

if you mean Orlando Sanford International airport, then it is there

florian

no I'm not talking about Orlando Sanford International airport (KSFB) but to Orlando International Airport (KMCO)

tomas

it does seem to have icon (POI), just polygon

florian

he is listed as an airport, what difference it https://www.openstreetmap.org/way/224534817 ?

POIs can be nodes (single points), ways or relations.

In May I reported a (supposed) bug about POIs where Navigator doesn't show POIs that are "relations" compared to the common "node" and "ways" POIs.

I never got any reaction.

It was this topic: http://forum.mapfactor.com/discussion/7148/poi-bug-with-park/p1

And as mentioned: The top one (Orlando International Airport) is again a relation where the second one is a way.

So a confirmation of the bug I also mentioned.

And no way to turn on openstreetmap a relation in a way?

hvdwolf

No, relations should be used when talking about relations. A way can be part of a relation.

This article explains it pretty well: https://wiki.openstreetmap.org/wiki/Elements

The simplest explanation could be a hospital consisting of multiple buildings. The buildings are ways and these ways belong to the relation hospital.

Or think of a building with an "inner hole" like a football stadium: It consists of an outer way (line of nodes) and an inner way (line of nodes). Together they form the relation of the football stadium (maybe even with a couple of smaller buildings)

and it is not possible to take the whole of the airport as an area?

hvdwolf

I suppose that is possible but you should never tag for some Navigation app. It's a bug in Navigator. When I tested with my relation bug in the other topic it could be found by OsmAnd and either MagicEarth or Maps.me. I can't remember which one I tested.

It would be terribly bad if someone put a lot of time in creating such a relation and someone else either replaces it or "doubles" it by adding an area.

Never try to "correct" good data because of a faulty app (in this case)

florian

I asked as most airports are represented as area (way)

hvdwolf

I understood what you meant, but defining an area is mostly a lot simpler than creating a relation consisting of a few or many ways or other relations. Some people spend a lot of time in defining objects into great detail. I have seen the same for train stations, shopping malls, cathedrals and again football stadiums and even old castle ruins.

It's like redrawing Michelangelo's "The creation of Adam" into some "stick figure" drawing because your child (Navigator) does not understand it.

You might undo some artist's creation.
