I just had a prospective client ask me about using the US National Grid as an index grid for a county-level bike map. Has anyone else run into this?
Given its apparent growing adoption by emergency responders, it may make sense for recreational maps, but I wonder about its universality vs lat-long for people using GPS units. Remember when some folks were saying we "must put lat-long on every map or we will lose market share once everyone has a GPS"?
I found this interesting document about implementation in cartography on the Minnesota state web. It looks like you could index just with a small subset of the long string, for (say) a 1 km square, or a 0.1 km square.
Thoughts?

I have never used Lat/Long on my hiking maps. I've always used UTM with NAD83. Apparently it is identical (at least the scale that I am mapping) to the USNG. Maybe I am crazy but I just like base-10 mathematics.
