23’000 Km of New Ways in 12 Months

Mid October 2012 I produced updated statistics on road lengths in OSM for Switzerland, a year later it is time for an update.

The statistics show an increase of a total of at least 23’000 km from 152’000 km a year ago to 175’000 km now. As already seen in the last update the length of all roads with higher classification does not show much movement, a clear indication that the major road network is very complete.

Growth is mainly due to the increase in minor roads, tracks and paths mapped, which in turn is likely to have been driven by improved coverage with aerial imagery in 2013.
