Where should I store a mosaic dataset? File geodatabase or Enterprise geodatabase? Currently we have a stand along Image Server(9.3) without ArcGIS Server installed on it, and users load image services via the ArcMap image server client. I am migrating our ArcGIS 9.3 image services and I was planning on using a fIle geodatabase located on the same server as our ArcGIS server. I was then going to share these out as Image Services to distribute to our end users. We will be using ArcGIS 10.2.2.
