Can anyone please tell me name of any country or city of world which has almost correct OSM dataset or which has better osm data quality. |

IMHO there is no such thing as a correct (or perfect) data set. For starters, the world is in constant movement: new buildings are erected, new roads are constructed down, shops close and new ones open. Although we try to catch those things are quickly as possible, we will always a be at least a bit behind the facts. Furthermore there are so many things that we can map besides roads and buildings: addresses, POIs (shops, restaurants), amenities (schools, benches, waste bins), etc. but also characteristics such as 3D properties, indoor mapping, turn lanes, surfaces, opening hours, etc. I could go on for awhile here. We could probably also keep on improving the accuracy of mapped roads and buildings, let alone of small features. I think we are nowhere near the perfect map. That being said, take a look at German cities, Nottingham or London in the UK, they are usually considered well mapped. Or perhaps any Dutch town, as they imported all buildings and addresses, which gives the map an impression of being complete. Perhaps it is useful that you extend your question to give us an idea what your definition of "correct" or "perfect" is. |
