In traditional image production workflows, imagery is processed in multiple steps, with the imagery being sampled multiple times, and being read and written to disk multiple times. This reduces image quality and production efficiency. The linear workflows also are susceptible to bottlenecks when a single parameter in the workflow is not available or needs to be changed. ArcGIS Image server enab...
