Copy-n-pasted impact data from the following web table...
http://www.solarviews.com/eng/crater.htm
Into the following excel spreadsheet...
impact.xls
Then edited Mjolnir Norway and changed "73°48N" to "73°48'N" (ie, added the single-quote, for minutes)

I annotate these locations onto a map using the annotate 'pie' function.
I shade the dots (pies) based on the size of the impact crater
(since the larger ones are more important, I want them to be "on top"
if there is any overlap of dots).

And, probably the neatest feature - I've set it up to "drilldown" to
a zoomed-in google satellite map, when you click on the dots (the zoom
is based on the size of the crater, so hopefully the crater will be
nicely visible in the google map).
