I have a set of images that I would like to publish to AGOL as a single layer (and further use it as a layer for existing web map). The problem is when publishing it as a service, estimated cache size exceeds 6 TB and I'm not sure what is the limit for publishing data as organization, I believe 6 TB is too much. I would like to ask if there is a way to combine my imagery to a single layer after I publish them all separately, so that I would have a layer rather than a set of layers under the group name.
Can you provide some more information?
What workflow are you using that 6TB was estimated?
Are you using ArcMap or ArcGIS Pro?
What size of area do you images cover? What coordinate system are they in?
What levels of zoom do you want the data to display at?
