This page is intended to collect all ideas concerning indoor mapping activities.

It is useful for tagging, to refer to the Simple Indoor Tagging schema.

Use cases

Indoor maps or information can be used for various applications, e.g.

  • Indoor Navigation/Routing
  • 3D Visualization
  • 2D Maps
  • Public Participation
  • Emergency response
  • Interested Amenities Display (e.g. Toilets, Fire Extinguisher, First Aid Box)

for different venues, e.g.

  • Airports
  • Hospitals
  • Hotels
  • Universities
  • Schools
  • Museums
  • Train and subway stations
  • Shopping Malls
  • Smart buildings
  • multi storey parking decks
  • other public buildings

The indoor/use cases page contains a list of venue use case examples, with sample maps from the venues, as well as various components of indoor addressing according to each case.

Description indoor= is a map that displays indoor data. A MapComplete theme: On this map, publicly accessible indoor places are shown.
OpenLevelUp allows to navigate inside levels of a building interactively and displays pictures from the web, Mapillary or Flickr. OpenStationMap is a project to map stations with routing, indoor, 3D and of course station specific features.
Simple indoor editor.

There is now a new subforum for Indoor-Mapping:

Let's try to increase the communication in this project. --Andi 12:03, 3 October 2012 (BST)

Make your indoor navigation app content discoverable

There is an API proposal you can implement on your backend to ensure other apps can link to your indoor navigation app.



For the current consensus see Simple Indoor Tagging. The tags below may be outdated or no longer used.

Tags in use

Please see Tagging above for more detailed information

  • level=n - indicates floor level; interpretation of the values varies (see key page)
    • <n> is usually an integer number, sometimes also one or two characters, sometimes combined (e.g. A,B,C,1,2,3).
    • in any case, <n> should be ascending (towards the sky).
    • in some cultures base level is indicated by level 0, in other cultures ground floor is level 1 (or A).
    • there are also usages reported where fraction numbers are used (e.g. level=2.5) indicating a "mezzanine" or "intermediate level" (e.g. intermediate stairway platforms).
  • room=yes - see key wiki page for additional values to describe the type more detailed. Room number ref=* and room name name=* are tagged as appropriate.
  • entrance=yes - building entrance
  • window=yes - windows
  • door=yes/hinged/sliding/no - interior doorways
  • capacity=* - the occupant capacity of a room, storey, building or part of a building defined as the maximum number of persons it is designed to hold
  • highway=elevator - elevators
  • highway=steps - stairways
    • conveying=yes/forward/backward/reversible - escalators
  • indoormark=beacon - Bluetooth, NFC, or QR beacon for indoor positioning.

Proposed Tags

  • indoor=yes - Indicates any osm object being inside a room, a building (or both) or a shelter.
    • mandatory has to be discussed, I would prefer an outdoor=yes for the difficult cases. --Saerdnaer 16:48, 28 March 2011 (BST)
  • highway=corridor - Indoor ways, under some previous indoor tagging schemes, and as of 2019 a de facto standard. Another de facto standard for mapping interior routes is highway=footway+indoor=yes.

Tagging proposals more concerned with the 3D shape of the building

Previous tagging proposals

There are also some abandoned and inactive proposals (oldest last):


Available renderers:


  • The altitude value of GPS devices could be used to identify in which level of a parking multi storey a car is located.
This won't be possible until someone invents a new GPS system that is a lot better at vertical accuracy. --Cartinus (talk) 14:27, 24 June 2013 (UTC)


  • To go from point A to point B, need to consider:
    • levels
    • stairs
    • escalators (conveying)
    • elevators (lifts)

Devices / Technologies

  • High sensitivity GPS device
  • Step counter
  • Compass
  • Acceleration sensor
  • Counting the number of wheel turns in cars / Tachometer
  • Counting the number of floor tiles
  • RFID
  • WLAN
  • Bluetooth
  • Camera
  • Audio footprint for rooms
  • Laser rangefinder (e.g. Hector SLAM [1])
  • Visual/Depth/Stereo SLAM (with software like RTAB-MAP [2])
