Not only a lot of features are missing but most of those visible are off by a great distance. And then it's also difficult to add landmarks to the scenary because there is no accurate reference point to help positioning objects. Will we use osm in the future ? And since osm is far from being exhaustif how to make a choice of wich one between osm and vmap to use to generate a tile ?
