Since people are actually posting on this... (which has never happened before)

How do you know which years to put when the question is like "x is in purple because it was built in between _____ and ______?") I never seem to get them right, and I always feel like the answer changes. Anyone know how to do 'em?

Off the top of my head, I seem to recall purple has to do with changes to the map that haven't been verified, or map revisions, or something of that sort. I think there should be something on the topographic map that explains what it means.

I never had a question ask that between two dates, but on the map, there would be a place where it tells you when the map was photorevised.

On most maps, the date of the changes made in purple will show up on the map in purple text in the bottom margin (I believe on the left side.) It probably says "Photo-Revision or Photo-Revised in (Date)" Sometimes it is tricky on some maps when there are 40 different years and they all mean something else with non-descriptive descriptions.

I know where they are, but all of the maps have something along the lines of

Topography taken by aerial photo in ______, revised _______.
Cultural changes in _________, etcetcetc. There are at least 4-5 years they mention, and then 2-3 more on the photo revision section.

Well, this is what I would do:
1) Usually, each map has a date where the data was field checked (or topo. was gathered)
2) Then, there is a date where the photorevision took place.
3) my answer would be the difference between these two dates. :D

What area topographic maps do you think they will give at nationals?
