Hi,

   I've added a world-wide license change map to OSM Inspector:

http://tools.geofabrik.de/osmi/?view=wtfe&lon=-1.80469&lat=35.88371&zoom=2&overlays=overview,wtfe_point_harmless,wtfe_line_harmless,wtfe_point_modified,wtfe_line_modified_cp,wtfe_line_modified,wtfe_point_created,wtfe_line_created_cp,wtfe_line_created

This is based on the per-object data I have on wtfe.gryph.de, combined with a current planet file. The view is updated nightly, and drawn on OSMI using a large bitmap for the smaller zoom levels, and detailed shape files for the higher zooms.

The shape files and overview bitmap can be downloaded separately from a temporary server (http://176.9.53.72/); the shape files are probably the easiest starting point for someone who wants to draw their own maps or make other analyses. They are quite large though (more than 1 GB each) so don't expect to be able to just open them in QGis ;)

Statistics are available on http://tools.geofabrik.de/osmi/munin.html, an detailed documentation on http://wiki.openstreetmap.org/wiki/Remapping/ODbL%20Layer%20on%20OSM%20Inspector.

I'm not sending this to talk/twitter/blogs etc just yet because I was hoping that some of you might test drive the service and do a few spot checks to see if it does what it is supposed to do. Such a spot check would typically consist of zooming in to an area where something is red or orange, clicking on the object to see its ID, then use the OSM data browser to look at the object history to see if that object really has a relicensing issue.

I'm happy for technical discussion to take place here but I'll send a similar message to legal-talk so that if there are questions more legal than technical, they can be discussed there.

Bye
Frederik
