I have been creating a map of a Golf course in North Branch Michigan. I have been loading the world imagery and at first, when I zoomed in past say 1:1000 to like 1:852, the image set would switch to a real nice, high resolution image. I even processed the golf course without any data to look at the image. That is the image I digitized some information off of, but, now when I zoom in, I don't get that final image set...it just stays on the one above it and just gets more blurry as you go in further. Why doesn't that last image come up any more? I have an example of the same spot on both. I can't get the nice one to come up anymore. Not a cache thing. That's all fine.
