OpenStreetMap
I have put OSM Analytic Difference Engine on github. In short its a backend for a live service providing real-time insight into edits within a region of interest. Special focus has been made to analyse the changesets and provide a concise description of what has changed.
Some of purposes of this engine:
- Prof-of-concept for an improved changeset-info service (improved compared to looking up changeset details on osm.org)
- Provide insight into changes in your area of interest
- Improve team spirit of a regional OSM team/task-force.
- Quality insurance through peer review
- Learning by seeing how other make edits to your region of interest.
The service is available as a web-service and provide three different information elements:
- An overall summary with a overview map containing bounding boxes of recent edits
- A list of changesets with analytic details
- A visual diff for the changes of each changeset (try the ‘VisualDiff’ link on each changeset)
Example of the analytic details:

Nice tool !
I often use achavi to view changesets, maybe you could add it next to Visualdiff ?

Very interesting. I love the concept of this.
How do you deal with non-atomic changesets? I can’t imagine generating the diff can be simple in cases you have changesets overlapping in time windows & affected feature sets.

(I am strongly of the opinion that we need to look at getting functionality like this integrated into osm.org at somepoint in the near future)

Nice.
Would it be possible to drive this using the augmented diffs from overpass so you wouldn’t have to hit the API for the history?

Hi,
I haven’t compared the features of the augmented diffs vs. what this tool does, so I really can’t say.

I’ve been asking myself the same thing - the information you pull from the official API should all be available from the augmented diffs, without needing to put any load on the official API. BTW, I’m currently running an instance of this showing changes in Franconia, but I’m not sure this will be a permanent installation yet.
