For a long time MapSphere data plugins provided the detailed data mainly for the USA. Now there are new layers with a larger world-wide coverage and usually a higher precision and accuracy. One of them is based on the free OpenStreetMap data, which is created by thousands of users who submit their tracks to a common database.
There are several features related to GPS and MapSphere Online. For example now while traveling with MapSphere you can specify your vehicle type and other users will be able to see it on their maps.
