Is there a way to extend visibility of cached Aerial Photo Image Service beyond the cached LOD?

[GerberMatthew]

Hi All,

Is there a way to extend visibility of cached Aerial Photo Image Service beyond the cached LOD?

I have a cached image service on ArcGIS Server 11.x that is cached to LOD19.  Due to the frequency of the imagery being updated, and that no additional clarity will come from generation more tiles, I am not wanting to increase the processing load to extending the cache to LOD20 or 21.

The users just want to be able to zoom in "Enlarge" the feature they can already see on LOD19.

Yes, I can make a basemap with both, a cached service down to 1:1128, then dynamic service from then on.  But I am seeing a return lag when switching from one service to the other, and when no addition detail is going to given, was hoping there was a setting/solution i could apply to the cached service.

PS.  I have found if I load the image services tile package into ArcGIS Pro and publish it as a WMS, it stays visible indefinitely.... but I feel this is a very awkward way of solving the problem.

Not sure if it would work for you, but have you enabled Resampling on the cashed Image Service?

Must also update the Min/Max scale for Resampling.

This used to only work in AGOL, but supposedly has been fixed in Enterprise now.

We have been using resampling with image services to accomplish what you are asking about. But it only works with the new Map Viewer (https://support.esri.com/en-us/bug/the-image-service-fails-to-honor-the-resampling-paramet-bug-00012...).

Set the resampling to your highest and lowest view scales and when you go to cache the image service make sure you uncheck any scales you do not need (anything below 1128 in your case).

Here are the Resampling parameters for one of our image services using the ArcGIS Online/Bing Maps/Google Maps tiling scheme. Our cache stops at 1128 for this service but the maximum scale for the resampling is zero so users can zoom in completely without the image disappearing in ArcGIS Enterprise or ArcGIS Pro.
