Has anyone created a SR4 Interactive Map (similar interface to Google Maps, Map Quest, etc) that shows stuff like where certain landmarks (Archologies), roads, boarder crossing points, and other relevant info?

There's a data set for Google Earth floating around. A search in DS should find it.

I have found using google maps at present a good way to generate street maps should they be needed. Just keep in mind what barrens means and that the strip of road has not seen a road crew in ove 50 years.
