Any News For Indoor Navigation?

I opened a new discussion named "floor maps, what's for ?". I was asking what I might do with that control, but nobody replied . I thought it might help to perform autonomous indoor navigation. I saw many old (3 years) community discussions asking for the same issue, but floor maps could't help, and there was no ezb solution for that. Dj Sures was working on that at the time, facing some problems. Are there any news ?
