I have a tpk that is 8.5 GB and uses a custom scale from 1:2400 to 1:40. This is high res 1 inch imagery but the areas covered are not very large.
When I go to publish the tpk in AGO the Manage Tiles button tells me there are 26 Billion tiles! ( Even after I remade it using 512x512). Manage is telling me it will be 1 PB just for the 1:40. It just keeps spinning and refuses to unpack anything.
Why is it showing such an enormous size when the tile cache is just 8.5 GB on disk? I did a Mange build with a AOI.
I did a one image test before and it worked fine - total of 7,000 tiles.
I can share if needed.
