  • Routing View EU 2010-11

    And again, here are the new statistics for the “Routing View EU“. Overall (according to the Geofabrik extract) the following amount of errors appear for Europe at the middle of November 2010: Unconnected Roads: ca. 107500 Duplicate Ways (number of duplicate segments): ca. 160000 Unfortunately this means that overall only 500 unconnected streets and 22000…

  • Growing agreement to contributor terms

    As I mentioned in an earlier post, since October 10th there is a list of OSM member accounts available that have agreed to the contributor terms. The file is available here and it will be refreshed every hour. I created a diagram that shows the increase of the number of accounts in the past. So…

  • How did you contribute to OpenStreetMap ? Version 2.0

    Since my last blog post there are some small improvements available for the “How did you contribute to OpenStreetMap?” website. The following picture shows the changes. First (1) I imported the new full history (10/22/2010) and normal planet dump file dated 10/27/2009. Completely *new* is the second OSM map which shows the “last” contributed node…

  • Change of OSM object numbers through relicensing – Vers. 1

    Most of you know that OSM will change its license. This means that all data of the OSM project must be relicensed and therefore the contributors have to accept the new contributor terms.

  • *.osm or *.pbf ?

  • Using OpenHeatMap

    Nearly three months ago I saw a tweet by mapperz (here). The tweet introduced http://www.openheatmap.com (OHM) : “Turn your spreadsheet into a map” . A very interesting tool. Unfortunately I completely forgot about it in the past weeks until last night. I was looking for an easy method to present some data on a map.…

  • Contribution in percentage

    Some time ago I saw a diagram on the OpenStreetMaps statistics pages which showed the contribution of OSM Data by contributor in percent (here). This diagram was created last year (2009). I tried to repeat this interesting analysis with the latest OSM data to see if there have been any significant changes. The following diagrams…

  • Routing View EU 2010-09

    The OSMI Routing View for entire Europe is available for two weeks now. I try to create the stats for the view once a month as I did before. For all readers that are not familiar with the Routing View, you can find some information about it here: OSM Inspector (OSMI) – http://wiki.openstreetmap.org/wiki/Osmi OSMI Routing…
