How accurate is open street maps?
The analysis shows that OpenStreetMap information can be fairly accurate: on average within about 6 metres of the position recorded by the Ordnance Survey, and with approximately 80% overlap of motorway objects between the two datasets.
Why is OSM so bad?
One of the most significant technical problems with OSM is the lack of a review model, that is for a change to the map to be staged and then reviewed before being applied. Not having this functionality caused ripples of problems throughout the system, some of which I’ll discuss here.
Does Apple use Open Street Maps?

Why is the accuracy of OpenStreetMap so important?
Accuracy of a map is as important as completeness. This page discusses sources of error, and how correcting other peoples errors based on one source of data can be a problem. OpenStreetMap is still in the process of building basic map coverage in many areas. The degree of accuracy that is reasonable depends on the existing data.
Is the open street map available for free?
OPEN STREET MAP IS AND ALWAYS WILL BE AVAILABLE FOR FREE. Don’t get me wrong, I use Google Maps almost everyday for real-time traffic information and as my main navigation app. It is a great mapping service. No doubt. But although it’s free of charge, there is a certain cost associated with using Google mapping services.
When did Foursquare start using OpenStreetMap data?
Telenav has started using OpenStreetMap data in their Skobbler navigation app. In fact more and more major organizations are choosing OSM for their maps. In February 2012, Foursquare switched to the OpenStreetMap powered Mapbox platform. In March 2013, Wikipedia started using OSM as well.
Is it safe to use an old map?
Old maps should be used with caution. They are likely to have inconsistent errors across the whole map, as well to more obvious problems – the above map also has some nearby hospitals for tuberculosis, many of which may have closed. Perhaps more important than absolute accuracy is how roads and other features connect.
