I can't find the instructions telling how to make a difference map. I'm at 99.6% and am really struggling with the last. Can someone tell me how to make the difference map using Photoshop. I've done it before but forget how. -Joe

Please, any help would be appreciated. Been wall hugging for days and can't find the last 0.4%. I created a high res stiched map and I'd like to do a compare on that too. map flipping isn't showing me anything. I know there were instructions here but I can't find the thread. -Joe

It's linked to here in Livingston's sticky, it's the 'LuXa' method. Essentially you layer both maps and photoshop can spot any differences. The problem is clouds and any imperfection of lining up register.

For future reference, map questions need to be refered to the mapping thread stuck to the top of each explorer forum.
