I am not hear about it yet but may be Google Map offer this service of indoor mapping. I will be search about it in English and then share here. Can you translate this article in English?
They have been encouraging building owners to survey their own facilities with a camera and post and contribute to the google maps internal street view team. I remember reading a post about it on a forum a while back.
How exactly are you able to do it? I saw a building on Miami beach that had their office done. I was able to drag the little orange man from the map and actually walk through their office. Is this something that google does for you or you do yourself and submit it to them
I assume, in near future, probably next year, this should be something, you do yourself by use of tango technology and of course submit it to them.
For me reason enough to develop our own, open source indoor maps.
Here map(http://here.com) introduced indoor mapping first and their collection is bigger than Google. Their 3D imagery is also better than Google in most places.
@Nagesh_Blr: please note that there is a big difference between the OpenStreetMap data and the map on osm.org. It is very well possible that some buildings are completely mapped in 3D and with indoor information, without this being visible on osm.org. At this moment osm.org does not show any indoor data at all.
You could use e.g. OpenLevelUp! to visualize the indoor data of OpenStreetMap
