I already tried adding a model based on its lat/lon. Unfortunately, the gps in mobile devices is not accurate enough to position the model exactly where I want it to be. It seems like no matter what I do, the real-world lat/lon is between 5 and maybe 20m off (even if I filter location results to be better than say 4m horizontal accuracy). If you don’t care about exact positioning and orientation, it could work. Say you walk around your neighbourhood and you see objects placed around certain locations like a park, sone other open area, etc. But if you want the model to always stick to exactly the same point, it will be a lot harder, even if you use third-party services like Mapbox.
