I am currently working on a project to map the bus transport in Iceland. I have a full list of all BUS stations along with their internal IDs (see here: names). Using the Nominatim geocoding tool from OpenStreetMap, tool I was able to pinpoint many of the stations to their approximate locations. In some cases the results were far off, like when the bus station Gerði was mapped to the town Gerdi, Afganistan. In some cases it threw no results, I then placed them in the Fossvogur bay, for the time being. So this is the result.
Here you can look at the map in detail. The coordinates come from OpenStreetMap/Me and that part is under a free Creative Commons Licence, the underlying map is from Google Maps and is copyrighted.

If you happen to live in the area and feel like adjusting the map, you can do that: It is open for all to edit under: http://maps.google.com/maps/ms?vps=2&ie=UTF8&hl=en&oe=UTF8&msa=0&msid=211352181949628755701.0004b6686d1871ab4b12a
(Note that when you click this link, Google Maps divides the PlaceMarks into four pages, which is kinda annoying, but can be lived with for such a small project.)
There you can also download the .kml file of the locations for your own purposes.
