Have you looked into implementing an indoor layer? #40

There are some proposed tagging schemas out there and many buildings are already stored in osm see: http://wiki.openstreetmap.org/wiki/IndoorOSM

We are considering looking into implementing something for this and I just wanted to see if you had given it some thought or if it was already underway.

Awesome project by the way!!!

Indoor layers would be a great addition! I had a look at it while experimenting with S3DB buildings but nothing implemented so far. As one should be able to highlight specific features dynamically I think the jts geometry layer that is currently in the making might serve as a base. I've put a very rough sketch in vtm-jeo repository, indoor_sketch branch (vtm-jeo is what I gave to another student as a start for writing the jts layer).

So basic rendering could be there soon. To cache objects sqlite might be worth looking at - not sure if android has rtree enabled but a simple tile index might suffice. A bit more tricky will probably to implement the object picking.. There is probably a lot more to do than I can't think of atm. Just go ahead and let me know when you are in trouble with OpenGL or some quirks in the library

the osmindoor.json is made with overpass-api: http://overpass-turbo.eu/s/2uq screenshot_2014-02-12-05-07-41 .
