During my really great vacation in Sweden I had some time to do some further adjustments to the well-known “Your OSM Heatmap“-webpage. For the new readers: “Your OSM Heatmap” shows the contributions of an OpenStreetMap user as a heatmap overlay. You can find my blog post with some more information here.

However, I think it would be a fantastic idea to add a time slider to the webpage. You can find it now below the map! The year of your first and last contribution is on the left and right end of the slider. With the slider you can visualize your OSMtastic-work over time. The following image shows the webpage including the time slider:

As a second feature you can now use, beside your OSM heatmap-link, the permalink of the map to point to an individual position of your heatmap! Finally I have updated the data for the webpage with the latest OSM changesets. Overall the heatmaps for about 150 000 contributors are available. Remember: Not *every* registered OSM member did contribute to the project.

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?

Last weekend I added some information to “How did you contribute to OpenStreetMap ?“. The “ChangeSets” (1) of an OpenStreetMap contributor can be seen now too. To be more specific, you get the following numbers:

• ChangeSets == Overall amount of your ChangeSets
• Changes == Overall amount of your changes within your ChangeSets
• First ChangeSet == Date of your first ChangeSet
• Last ChangeSet == Date of your last ChangeSet

You can make this information visible by clicking the “more“-link (2)! In the following picture below you can see the new add-on:

Notice that the date that is shown in the ChangeSet-information field (see image above) is always the same as the date that is being displayed underneath the “Your last Node … “-image (3). Check it out here: http://hdyc.neis-one.org
