Map Help?

[weknowhowtolive]

Hello there, I like the forum!

I'm trying to find some very detailed map information for Civil War battlefields. I'm currently trying to help a group of people make a very detailed and historically accurate Civil War MOD for a game. I've found some good overviews with locations of blocks of troops, buildings, etc, and its helpful, but i'm also looking for stuff more like this

http://www.civilwarbattlefields.us/chancellorsville/chancellorsville_0005a.jpg

except....more readable.

I dont know if they exist, I've seen them for other wars, and of course, arial photographs for WW2 and such, but I'm having a hard time finding civil war maps that arent just blue and red lines.

I'd also really like some good pictures of the area, either old or current.

Thanks for any help in advance!
