I am trying to display historic Sanborn maps over aerials to show changes over time. I georeference the images and then build mosaic datasets in ArcGis Desktop in order to create a tile package and share the package to ArcGis Online. This technique has worked well for other years that I have done (project introduction: http://olympiahistory.org/category/historic-map-overlays/ .) In the latest map, there seems to be ghost tile fragments that are outside of the are covered by the Sanborn map that appear at different scales. I think that the ghost tiles are fragments of overviews.
After you get tiles published on ArcGis Online, can I somehow turn tiles off and on to see if I can get rid of the ghost tiles? I tried tile manager on the the layer detail page, but that seems to just publish more tiles and not get rid of the ones I don't want.
This is a link to the map with which I am having trouble: http://arcg.is/1K7rBEc I am also attaching an annotated image of one of the ghost tiles.
