[Taxacom] odometer georeferencing

Like many who antedate 1995, I've got a huge body of observations 
"georeferenced" by odometer readings along highways.

Kari Gunson - http://www.eco-kare.com/ - has proposed to GIS these by 
listing the geographic co-ordinates of every 10m of the highways they're 
along, so I'll just be able to select reference points from web maps, 
calculate the distance from the reference points, and then assign the 
observation the co-ordinates that match these distances.

I wonder if this method has been used by others, and if there's any 
place where such tables are archived? I haven't tried to search for such 
accounts on line, since I don't know what the method would be called.
