Howdy: Here at U of U, I'll soon have two projects going in the Map
Collection: a major stack shift; and retrospective conversion of topo
sheets, including reclassing the different series which have
historically lodged together with the 7.5-minute quads. I'm trying
to plan for the space needed for these series. Does anyone have
statistics on the volume of sheets produced in the obsolete series?
These are: 30-minute maps at scale 1:125,000;
60-minute maps at scale 1:250,000;
1:31,680-scale maps;
6-minute (scale 1:24,000); and
15-minute (scale 1:48,000);
And do I understand correctly that the 60-minute maps were confined
to the western states, while the 30-minute ones were primarily
eastern states? Thanks... Ken Rockwell
