Subject: Re: Seeking Map Count for USGS Topos by State (fwd)
Hi;
I have a list of total quads per state. Each count includes all 1:24,000,
1:100,000, and 1:250,000 maps for each state, including all border
sheets. I can break out just the 1:24,000's if that is what you want. Any
given border sheet is counted in each appropriate state count.
I'll be happy to either post the list to Maps-L or send it to anyone that asks.
Thanks,
Russell Guy
