We have a lot of students at WSL (Swiss Federal Research Institute for Forest, Snow and Landscape Research) who are doing stereo interpretation. They are not trained in correctly setting the height of the cursor (e.g. on top of a building or a tree).
A “Split Screen” mode would help them to get trained: in the top part of the Stereo Map there is “Default” (both images on top of each other), in the bottom left part there is the left image and in the bottom right part the right image. When the cursor is at the exact same location in the left and right image, the height is correct.
