It's pulled from the same information that generates the 24k topo, but 
it looks to be a relatively new venture and is being honed as people 
with specific skill-sets come into the mix.  There are a number of 
threads about it on the Groundspeak forums that I came across today 
dealing with the building project that is...everything.  Even if this 
isn't as detailed at a true 24k topo map, it's SO much better than the 
100k stuff Garmin puts out.  Maybe it's a 1:25000 scale.  :)
