Hi Matt I am trying to overlay AGS created cache layer over a KaMAP created Cache Layer of the same data set. However, even after following the tips in this forum, I am unable to get them lined up. The AGS layer is not lining up at the correct coord position. I have generated the AGS cache and set the layer creation with the right extent and tile origin.
Though your e-mail is dated May 16 2008, Hopefully May I seek your help in trying to resolve this? If so I can provide more info on my problem.
