I have a high resolution imagery set 6" per pixel that I would like to create a basemap from. The resulting tile service looks good until you zoom out to between the 1:1000 and the 1:5000 scale. At this point the edges get very jagged. Do I need to insert another scale value? say 1:2500? would that allow it to still work well with other cached data or would I need to have all the reference layers cached with the same set of scales?
In writing the question I'm betting I do need to add a scale value to get the quality I want at that zoom level. The biggest question now is what impact would customizing the scale values have to the responsiveness of other tiled layers displayed on that basemap?
