Underground malls are often mapped with location=underground and layer=-1 and more negative values can be used for the underground levels of features within the mall.
But how should we specify the location of an entrance to the underground mall? There is an amenity=parking_entrance tag for the entrance of an underground (or aboveground) parking structure, which allows routing and rendering applications to show this location specifically. It could be useful to map the location of the mall entrances, both for underground malls and large above-ground malls, so that the main mall entrances can be located separately from all the individual shop entrances. T he tag indoor=yes can be used with entrance=yes to show that this door is within the mall, but there isn't a specific way to show the main entrance/exit from the whole shopping centre, when the outer way of the area doesn't intersect with the entrance=yes node. This would be common with underground malls, where the entrance may be inside of, or even outside of, the polygon that outlines the area of the mall, because the escalators or stairs are usually not right at the boundary. Would something like entrance=mall or mall=entrance work? Or do we need a subtag for entrance=yes? _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
