ThinkLemon’s been working on this for a while, and now his KML lists of impact structures have become quite the resource. Another must-have, for schools as well.

Notes on the political and scientific impact of digital maps and geospatial imagery
Thanks for mentioning. :-)
I am thinking about other ways I could distribute the data like ‘the smallest impact craters’ or ‘the most recent impacts’. So this won’t be the last. Maybe I’ll dabble with the Google Maps API…
I’ve also been thinking about building a list of (super) volcanoes in the same manner. But it seems others are working on that already. Besides that, most volcanic data mentions height, but not the (crater) diameter.
