as far as I understand current indoor tagging scheme focuses on rooms (e.g. a room has name and maybe a function). But imagine the situation for really large rooms, for example an airport or even a large supermarket. There you’ll have different sections within a single room, e.g. border control, arrival gates, departure gates or in the supermarket example greenstuff department, drugstore, wearables and so on. Thus the existing tagging wouldn’t help if I don’t invent “virtual” rooms.
I would like to hear your ideas how to map that? Also let me know if I misunderstood something with the existing mapping proposal.
I think, border control is zone so you can draw it as area (like room). Good solution will be make a zone with multipolygons and add specific tags to walls (ex. barrier). In the future routing can use this (one wall open on another room). Maybe has someone better idea?
The problem here is, that the proposed tagging schema at http://wiki.openstreetmap.org/wiki/IndoorOSM doesn’t feature zones. According to wiki there are buildingpart=room, buildingpart=hall, buildingpart=corridor, buildingpart=verticalpassage, but in general I think that scheme is more or less ‘room-based’. I don’t see how to tag anything within a room, corridor or hall.
