Linda,
I believe Brian is asking for a state-by-state breakdown of how many sheets
cover each state. Let me say that this is a bit tricky in terms of counting
because each state has what I call "border quads" that overlap two states.
However, if I can start the ball rolling, I believe Pennsylvania is covered
by 884 quadrangles at 1:24,000. Maybe there's a quick machine-method of
converting the overall data count into state-by-state but if not then the
next best thing would be to have a librarian from each state report in and
Brian can build a database from there and then share with everyone?
