Hi Jeff, I was looking for the helpful or answered option for your last post, but the best I could do was Like it. Maybe because I hijacked Josef's discussion I don't have permissions to mark it answered.
Working on it. Details:
One of the good things about vBulletin was that every thread and every post had its own unique URL. We used that in order to move stuff over and fully redirect everything. We have a database of all reply posts that were marked as the answer (the green check mark) either by the original poster, and MVP, or a Moderator. We have to get that information moved over asap. Until then it's not even possible for us to manually mark them one-off unfortunately.
I know this is an old thread but this was very helpful. I found my tiling scheme file under C:\Program Files (x86)\ArcGIS\Desktop10.5\TilingSchemes and added in the few lines of xml noted above. I am uploading UAV imagery to ArcGIS Online and kept running in the zoom issue until I found this...Thanks!
