MINSCALE/MAXSCALE questions, cont'd

[Stephen Woodbridge]

There is no intuitive way that I have found to relate scale to maps
areas. I typically set up my scales using:

20M, 4M, 2M, 1M, 500K, 150K, 50K, 25K, 10K, 7.5K, 5K, 2K

Or something like that. Where the image is 300 x 200 and the width in
miles below are based on the scale bar

20M is VA, OH and north to all of ME or 1200 mi
4M is roughly MA, CT and RI or 120 mi
2M is roughly 60 mi
1M is roughly 24 mi
500K is roughly 8.5 mi
150K is roughly 2.4 mi
50K is roughly 1.2 mi
etc

This should give you an idea of what value ranges you should be looking at.
