Routing View EU 2010-12

by Pascal Neis - Published: December 24th, 2010

Short update with new statistics for the “Routing View EU“. Overall the following amount of errors appears for “Europe” at the middle of December 2010:

  • Unconnected Roads: ca. 112600
  • Duplicate Ways (number of duplicate segments): ca. 139000
  • read more about the error-types here

This means that altogether there are 5100 new unconnected streets and 20000 duplicate way segment errors have been fixed (last month we had 107500 unconnected roads and 160000 duplicate way errors). In total we have an increment of 1300000 (+4.6%) new OSM way segments for routing in the past 5 weeks in “Europe” (this is nearly twice the number in comparison to one month ago)!

The following image shows the amount of errors divided by country for today’s Europe dataset:

In the past month several other countries were able to reduce the amount of errors, such as in: Austria (-3200), France (-4400), Italy (-2100), Portugal (-1200), Sweden (-2000), Switzerland (-4828 !!) and the United Kingdom (-3700). So I think the award for this month goes to Switzerland 🙂 . Germany keeps going on with its negative trend: A gain of about 2700 errors! It seems like the German OSM community is primarly tracing from Bing-imagerys, doesn´t it?

In the following diagram the bars for each country shows the total amount of errors for 1m, 2m, 5m unconnected & duplicate way segments:

As usual for Germany, the comparison of federal states (includes the error type “Unconnected 1m”):

(Nearly all federal states have a positive value regarding the amount of errors, except Rheinland-Pfalz, Sachsen, Schleswig-Holstein & Hamburg)

This was my last blog post for this year, so Merry Christmas and a Happy New Year 2011!
