Hello Peter,thank you for your comment.Indeed it seems to be quite difficult to achieve indoor mapping with OSM and JOSM at this moment. However there's currently a great deal of research being invested by universities on this topic. Our university (TU München) had several bachelor theses on the topic and our computer science department got mapped to some degree in multiple layers (see http://www.openstreetmap.org/?minlon=11.6665525436401&minlat=48.2617683410645&maxlon=11.6693410873413&maxlat=48.2632865905762). Me and three other master students got asked by our university to create a prototype routing application for Windows Phone as part of Imagine Cup. We are currently getting support by Microsoft and several local public transport organizations to connect valuable data into the prototype. I think when it's possible to prove that there is demand - by endusers and companies, more OSM users get interested in mapping buildings in their environment. Having a standard at that point in time will be crucial. There's already a lot going on with staircases, layers and certain elements on these layers. However there is nothing yet on doors and the mentioned feature proposal seems to fit naturally in there. I have been reading into OSM now for two days so I barely scratched the surface but I guess a CS graphics chair could add 3d plugins to JOSM to enable layered mapping. Do you know of anything in that direction?  Andreas

    Hi Andreas.


    I am kind of a detail mapper (mapping sidewalks as own ways and so
    on), but I am not sure about indoor mapping in general.


    All OSM editor programs I know are not well fitting into the area of
    editing more than one level/layer: bridges are okay as nodes are not
    on the same location most often, but more is difficult.

    If you ever tried to map a stairway from basement to the first floor
    (or above) of a building, winding around in between, you will
    probably know what I mean.


    Mapping rooms is similar: Often Walls are exactly on top of each
    other (as they carry the building's structure and roof).


    You see: mapping rooms is not trivial in general, but IMHO the
    problem is even bigger, if one already mapped the rooms of a
    building, while another one wants to fix e.g. the shape of the
    building itself (this may happen often).

    What to do now with the rooms?

    Of course that's a problem we always have when editing other's work;
    but here it's really much data that has to be corrected, and it's
    difficult to do so.


    Room entrances of course are only useful in combination with rooms -
    so that's my answer to your question.



    I would appreciate additions to JOSM (and other editors) helping to
    deal with problems like this: multiple levels, the always discussed
    problem of parallel osm-ways describing a road and so on.

    If there would exist software support, I can imagine useful
    additional mapping, yes.

        There is a feature regarding entrances to buildings. For me it
        seems to be suited for indoor mapping to be used for entrances
        to rooms too. Would be nice to get comments on this.
