Add rendering for amenity=marketplace

[sommerluk]

It would be nice to get rendering for “amenity=marketplace” with an icon and its name.

Some facts:

– 22 827 objects with “amenity=marketplace” in the database

– Wiki says to use it only an areas, not on nodes. But taginfo say that nearly 50% of the usage is on nodes (and the other 50% on areas).

– Is often used together with “building=yes” (20% of total usage) and “landuse=retail” (10% of total usage)

isn't this either already covered by the additional tag building=yes or
highway=pedestrian+area=yes ?

Not for some martketplaces - https://www.openstreetmap.org/way/115973623 - multiple buildings, parts of buildings, this area is not highway=pedestrian+area=yes (rather multiple highway=service + foot=yes), inside larger landuse=retail

• multiple buildings, parts of buildings, this area is not
  highway=pedestrian+area=yes (rather multiple highway=service + foot=yes),
  inside larger landuse=retail

I see, still there seems to be some outdoor area missing like
highway=pedestrian+area=yes or highway=* + area=yes and the mapping looks
kind of preliminary (the boundary is very rough and not quite precise)

This seems to be duplicate with shop=market (which is less commonly used).

For market places that are nearly permanently in operation, rendering makes sense. The same holds for markets that are not permanently in operation, but for which the market stands are always there.

I'm not sure about rendering weekly markets on city squares, of which no presence on the ground is visible other than the day they are in oepration.

Unfortunately, the wiki isn’t very clear about that. So I fear that in the database we have both (permanent markets und weekly markets) with the same tagging: amenity=marketplace.

what if the market is there Mondays, Wednesdays, Fridays and Saturdays?

I think if it's a regular market place, it doesn't have any other important objects which could be in conflict, so the exact opening times should be tagged with opening hours tag, like we do with shops - this is a social agreement to expect it to be working/present in some days/hours/times and not in the others, but the most important thing is where they are located.

there are both cases: markets that close (no access, shops closed) and markets which are typically public squares and open all the time but where the shops/booths close
or leave.
On the marketplace object I'd use opening hours only in the first case, otherwise service_times might be more appropriate. For individual stands / shops we would still tag opening hours as usual.

Still no change ?

[kocio-pl]

As far as I can see, the discussion reached no conclusion yet. Any ideas how to get there?

Maps.me has this icon :

Rendering could be with an icon and name for both, points and areas. And for areas additionally same area rendering like for retail.

The icon could look like one of these:

2:

This one is maybe nicer.

3:

This one works maybe better when there is noise in the background.

Amenity colour or shop colour?

[kocio-pl]

I guess 2 (the solid one) fits better our icon style. Shop color should be more informative, since we use brown for many different things.

[sommerluk]

Some more icon versions:

4:

5:

I tend to use number 5 it is both

• solid
• closed shape that works well on noisy background

About zoom level: Supermarket starts at z16 with its own icon, most other shops start at z17 with a dot, and at z18 with their own icons. I tend to start with marketplace also at z17, but directly with the icon.

The wiki says: 'The traditional market square is a city square where traders set up stalls and buyers browse the merchandise.'

I suppose that includes market squares that have a weekly market but without fixed amenities. That includes market squares in most European cities. Do we really want to render them all?

why not, they are usually very significant for the settlement

My local experience is that most of the time this is only their historical role. Today they tend to be just regular city square with shops around, not booths inside.

[sommerluk]

I would say that these cases should not be tagged with amenity=marketplace.

In West Africa, this tagging refers normally to a real marketplace currently in usage. It exists also in almost all bigger towns, aside of supermarkets. And in most villages, it is even the only place where you can buy food, so it’s often at a central place in the village and an important place for the life of the village.
