Last week Stephan released the neat “Where Did You Edit?” webpage. A world map indicates where in the world you have been editing OpenStreetMap (OSM) nodes. Unfortunately it is based on a full history OSM planet dump which is nearly two months old. Also, the map does not include any tools to zoom into or drag the map. However, Stephan mentioned that he is working on these functions. Keep up the good work, Stephan!

Based on my OSM changeset table of “How did you contribute to OpenStreetMap ?” I created a slightly different webpage and used a different approach. I used the weekly OSM changeset files and I presented the results in an OpenStreetMap including zoom and drag functions. Your contributions are indicated by a “Heat-Map-Overlay”. For this overlay I am using Bjoern’s OpenLayers addon. For better performance I generalized the total changesets of each OSM contributor. This means that it is possible that not every little contribution from a member is taken into account and displayed in the map. Anyway, I think the results are quite impressive, aren’t they?

The following picture shows the heat map of Harry’s OSM contributions. Really nice! But honestly: Harry, did you visit all places in person? 🙂

I think you will find other incredible OSM Contributors Heat Map stories?! You can find “Your OSM Heat Map” (aka Where did you contribute to OpenStreetMap?) here: http://yosmhm.neis-one.org . I can update this website every week if you like …
