I have compiled a complete tour of all the known impact sites on earth from the Earth Impact Database including a few overlays. Please let me know if there are any problems and if you have better data for some of the more obscure craters.
I would welcome any feedback from those of you who have tried it, both positive and negative. Replies in this thread would encourage me to continue the work.
If you wish to keep the download up to date keep checking back on this post. I am making regular updates to the tour. Even better you could toggle it as a favourite thread and then receive an email when it is updated.
