At WSL (Swiss Federal Research Institute for Forest, Snow and Landscape), we are currently using ArcMap with Stereo Analyst for our stereo interpretation tasks. We currently have three stereo applications and three full time stereo interpreters. In our applications, the interpreters work at a sample plot for about 10 minutes and then go to the next one (which is usually on another stereo pair). This workflow is smooth because the stereo images are programmatically loaded using the SDK.
We can only migrate to ArcGIS Pro (Image Analyst) when stereo images (or mosaic datasets) can be loaded automatically. Otherwise, it takes the interpreters too much time to manually load them.
