Editor popularity II
Just for fun, here’s an animated one:
Each frame shows the majority editor in each pixel over a moving 7-day period starting at the date in the lower left of the frame.

Editor Popularity
A while ago, I made a visualisation showing which were the most widely-used editors for OpenStreetMap. This was based on the created_by tag, which isn’t an ideal way to do things because different editors treated that tag in different ways. Since the API 0.6 upgrade, there has been a better method: changesets.
Each pixel is coloured by what proportion of changesets intersecting that pixel were uploaded by that editor; red for JOSM, blue for Potlatch and green for Merkaartor. Don’t read too much into it, though, as the editors have different behaviour when opening and closing changesets.

Wembley Mapping Party Animation
Here is an animation, like this one, but for the period covering the Wembley mapping party a week and a bit ago.
A high res version, which is much, much better, is here.

Party Progress
I’ve been playing with the diff import for osm2pgsql, which now works wonderfully, and trying to set up a (nearly) live tile-server. To test it, I set it running over the weekend after the Euston micro mapping party, grabbing some tiles every hour and turning them into a movie. It covers the period from about 5pm Friday to 10am this morning with one frame per hour.
