Resizing topographical maps?
I have a USGS 1:24,000 scale map (saved in PDF) that I would like to resize to a 1:25,000 so that it can be used with military protractors. Will resizing the map affect the accuracy? Does anyone have experience with this? Mathematically it should be reduced to 96%, but when I simply hold the protractor up to my monitor (viewed as full size) it appears to require reduction to 91%. Any advice on this matter?

Your screen is likely not accurate, so ignore what you measure on the screen. The calculation is correct, and printers should be more accurate than screens so print at 96%. The accuracy of the map should be materially unaffected.
