Osmose-QA is a quality assurance tool that detects issues in OpenStreetMap data.
It detects a very wide range of issue types. It is also useful for integrating third-party data sets by conflation.
Feel free to report any problem, idea or new open data you want to add to Osmose on our Github: Osmose-QA
In no case Osmose-QA should provide you the absolute right way to map, always keep a critical eye.
