OpenData vom Bundesamt für Kartographie und Geodäsie vs. Crowdsourced OpenStreetMap in Deutschland – Ein Vergleich Offener Daten
Nach knapp 1.000 Tagen Abstinenz (endlich?) mal wieder ein Blog Post von mir. Aufgrund des inhaltlichen und räumlichen Bezugs diesmal auf deutsch. Ein „offizieller offener“ Datensatz von einer Bundesbehörde? Gut, wie sieht’s im Vergleich zu gemeinsam zusammengetragen Daten aus, z.B. OpenStreetMap? Lassen sich Unterschiede in der Qualität feststellen? Sind die Datensätze womöglich auf Augenhöhe oder…

#100 – Thank you!
While I was working on my latest blog post, I realized that I had already written 100 posts over the past nine years. All posts have one thing in common: They are about the well-known and maybe never ending OpenStreetMap project …

New metric for measuring the “qualitative nature” of OpenStreetMap activities @ How did you contribute ?
Back in June we had a twitter chat about potential new features for the “How did you contribute to OpenStreetMap” (HDYC) website. One suggestion was to “show more relevant information about skills, tagging system or the quality of contributions” of a project member …

Additional insights about OSM changeset discussions: Who requests, receives and responds?
Last year I wrote two blog posts about the OpenStreetMap (OSM) feature that allows commenting on contributor map changes within a changeset. The first blog post showed some general descriptive statistics about the number of created changeset discussions …

Adding Indicators to OSM Map Edits Assessment
Almost two years ago I published a web service that finds suspicious OpenStreetMap (OSM) map changes. You can use the service here and find some more information in previous blog posts. Especially Changeset discussions revealed that they are more or less de facto standard for communication between contributors during map change reviews. However, when I…

Public profiles on “How did you contribute to OSM?”
The web page “How did you contribute to OpenStreetMap?” (HDYC) provides individual detailed information about project members. Some time ago, the page has been revised, that member profiles can only be accessed, when users logged in with their OpenStreetMap (OSM) user account. This feature has been implemented, after a long…

Review requests of OpenStreetMap contributors
– How you can assist! –The latest version of the OpenStreetMap editor iD has a new feature: “Allow user to request feedback when saving”. This idea has been mentioned in a diary post by Joost Schouppe about “Building local mapping communities” (at that time: “#pleasereview”) in 2016. The blog post also contains some…

Detecting vandalism in OpenStreetMap – A case study
This blog post is a summary of my talk at the FOSSGIS & OpenStreetMap conference 2017 (german slides). I guess some of the content might be feasible for a research article, however, here we go: Vandalism is (still) an omnipresent issue for any kind of open data project. Over the past few years the OpenStreetMap…

Reviewing OpenStreetMap contributions 1.0 – Managed by changeset comments and discussions?
The OSM project still records around 650 new contributors each day (out of almost 5,000 registered members per day). Some countries (such as Belgium or Spain) already provide platforms to coordinate the introduction to OSM for new mappers. Others use special scripts …

A comparative study between different OpenStreetMap contributor groups – Outline 2016
Over the past few years I have written several blog posts about the (non-) activity of newly registered OpenStreetMap (OSM) members (2015, 2014, 2013). Similarly to the previous posts, the following image shows the gap between the number of registered and the number of active OSM members. Although the project still shows millions of new…
