Kelly Gerrow and anyone else!
Q -In addition to the resampling parameter and max scale, what other service properties need to be modified to show the cache below the original lowest scale?
It appears the example link you provided (including my own hosted tile layers) still shuts off below 1128 even with resampling on and the max scale property =71. Is that what everyone else is seeing or maybe I'm missing something? (wouldn't be the first time, and won't be the last!)
Both of our services (we have same the cache scales, max scales, and resampling properties) only show through LOD ID 19, even though we've explicitly set max scale to 1:71 (or LOD ID 23) and have resampling on. Once you zoom below to LOD 20/1:564 and lower, our layers shut off (and cannot be turned on).
Important side note - using this workflow for ArcGIS Server Services
I was able to successfully use this workflow for my ArcGIS Server cache map service (and image services) to display below its LOD ID 19, however, I had to take one more step: I had to run the "Manage Map Server Cache Scales" tool in ArcGIS Desktop in order to add the LOD's to my service. This created the extra LOD's in my service, albeit empty tiles (which is what I want - to just show the tiles from LOD 19 at levels 20 thru 23 instead of generating a cache for those levels). Only after I completed this step, did my cache stay on (resample) at LOD 20-23.
Q - My experience using ArcGIS Server/Desktop to get this to work leads me to wonder if there is a similar function available using the Rest Admin Interface in the hosted environment (tiles.arcgis.com admin)?
Q - Does the "edit" function allow syntax that would enable you to add another level of detail, similar to the running the ArcGIS Desktop tool "Manage Map Server Cache Scales" on a cached map service?
I did try running the Manage Map Server Cache Scale tool against my Hosted Tile Layer, but I get blocked (probably rightfully so due to access constraints) with an error code: ERROR 001195: Could not connect to the caching service on the server. The caching GP service may not be running on the server./failed to execute.
Any advice would be great! I think i'm all hacked-out until I get some input from the community. thanks!
