markalex2209 (May 29 2024 at 19:25): markalex2209 (May 29 2024 at 19:25):I have question about malls. This two in particular: Rimi in Jelgava and Rimi in Daugavpils, but in more general sence about all similar cases.
If retail building is mainly occupied by supermarket and a bunch of smaller stores along the entrance, is that considered a shop=mall or not? And if not, how those buildings should be tagged?
Also, should a separate POI shop=supermarket be mapped inside of those buildings?
HellMap (May 29 2024 at 19:38):shop=mall is a bit of a troll tag, because it's technically not a shop but a location with other shops. So it should only really be used to group shops that are un the same location/building. If you think of it more like "amenity=mall", then you can add it to the area - building.
HellMap (May 29 2024 at 19:40):If a significant portion of the building is a single shop, like a supermarket with auxiliary small shops, then usually the whole building gets the supermarket tag and then only individual shops are separate. But this is subjective though - when does a primary shop become not the "containing" shop? This has a lot to do with perception on the ground. I'm not sure there is any agreement on this.
HellMap (May 29 2024 at 19:42):Vivo should probably be a mall or just retail building with shop points in it. Daugasvpils Rimi should likely stay the whole building but tagged as supermarket, not mall (although I can see an argument why someone might call it a mall).
markalex2209 (May 29 2024 at 19:50):What about additional nodes?
I assume if whole building is tagged as shop=supermarket there should not be a separate point, but for malls and general retail buildings it should be?
HellMap (May 29 2024 at 19:55):If the building itself is a supermarket, then it would have the name Rimi and whatever tags, so no separate nodes, no. Only for other small shops and places. For generic buildings, yeah, the Rimi or whatever would be its own node or even area if one maps it more accurately
markalex2209 (May 29 2024 at 19:59):Yep, thanks for explanation.
And now paying a bit more attention I see that this is exactly the way shops are tagged.
Probably I was a bit confused by how they are rendered. For example, here I thought whole building is tagged as supermarket, and additionally there is a node for supermarket. But it was only an icon added in the middles of area. :man_facepalming:
Rihards Olups (May 29 2024 at 20:15):I tend to differentiate as was suggested. If there are multiple shops in the building, the building is a mall, then nodes for individual shops - or areas, if something resembling floor plan is available (like at https://openlevelup.net/?l=0#18/56.98243/24.20345 ).
Edge cases - there's just one additional POI. For example, Rāmkalni cafe in Depo (https://www.openstreetmap.org/way/91892404), or a florist Puķu Elvis in Elvi.
Although sometimes the latter will have additional shops, making it easier to decide - https://www.openstreetmap.org/way/113899547.
Note that both of these example buildings not mapped as mall, one is building=commercial, one building=retail. Might be another thing to unify and document.
Rihards Olups (May 29 2024 at 20:17):As for the example in Daugavpils, that seems wrong. I'd move Rimi to a supermarket node and remove name from the building way.
markalex2209 (May 29 2024 at 21:16):I tend to differentiate as was suggested. If there are multiple shops in the building, the building is a mall, then nodes for individual shops - or areas, ...
I'd say that this somewhat inline with wiki for mall (at least my reading of it). But such an approach would result in almost all standalone buildings of Rimi/Maxima needed to be tagged as mall, since I think all of them have this row of smaller businesses. And quick check in overpass doesn't seem to indicate that this is how shops are tagged now.
Rihards Olups (May 30 2024 at 10:01):It's kinda close to that, except that mall tag is not used that often - usually used when the shopping centre itself is named.
Another example of building=retail: https://www.openstreetmap.org/way/219117487 .
markalex2209 (May 30 2024 at 14:04):This is a reasonable rule of thumb.
markalex2209 (May 30 2024 at 14:10):Maybe one exception would be a T/C Minska, but it's so strange, that I don't want to touch it: multiple addresses, multiple entrances to unconnected parts (a couple casinos, a proper mall and a supermarket with small businesses along the entrance, and a couple more business accessible only from outside)
Rihards Olups (May 30 2024 at 16:24):Haha yeah, I recently was there and it indeed seemed rather messy, and it had this "nineties, barely post-occupation" vibe :D
I wouldn't mind having Biķernieku Rimi and others tagged as malls, it could be slightly more consistent.
Although the question is how many extra shops would make a mall.
https://www.openstreetmap.org/way/159875789 seems non-mallish.
