I wanted to know, are there any formats/data structures made specifically for indoor mapping? I have looked at OpenLayers + GeoJSON however:
How will I sync up the coordinates of my local map and the ones GeoJSON uses? (I think this is done by georeferencing the map if I understood correctly)
How will I handle different floors and manage routing (when I eventually come to that) if GeoJSON has no support for that?
That's why I wanted to know if there are any specific solution that would be beneficial for making an interactive indoor map with support for multiple floors and routing!
I've already looked at a bunch of questions which helped me a lot, but I haven't found a good answer to my questions.
