Mark, Take the pixel size in meters and multiply by 4,000; that will get you close. So for a image with a pixel size of 5 meters, a good scale would be 1:20,000. Any larger than that (say 1:10,000) and you'll start to see pixel edges.
Unless you meant something else?... Best Regards, Brent Fraser > Hello, > > I created a tile index for an air photo.
