I am having trouble finding collarless 7.5 minute topo quads for use in ArcMap. Is there a way to remove collars from these files? I downloaded Tiff files and they are already in the right projection and everything so I am hesitant to mess with them too much....
any advice?
Collarless maps?

Global Mapper. It has an option to automatically remove collars, works on DRG's but also many other maps with collars.

Agree. Global Mapper works great. If it is just a few that you need, you could try seamless.usgs.gov as it will give you the continuous coverage. Or just reply or pm me and I can cut the collars off for you.

The ones available from geocomm.com already are collarless for many areas.

Dependent on your scale... USAPhotoMaps is free and downloads the TerraServer maps, which it can export to JPEGs w/ world files quite easily... The only caveat is it fails when crossing UTM boundaries. Still, a very nice, easy program.

I can also recommend Global Mapper, it's highly recommended. I personally used it and it works really great.
