Hi!!
I am speaking to a group next week about material in our Map Collection.
I was trying to verify some info that I thought I had read on this list ---
that there are 55, 000 --- 7.5 minute maps
and that USGS completed mapping the entire US at this scale in the last
5 to 7 years????
How far off is my memory??
Called USGS and they didn’t seem to have this info at their finger tips….
thought someone on the list might.
Thanks
