I'm displaying two (or more) geo-coincident images that are locked in roam and zoom. When I move the system cursor over image 1, I want to see a cursor(s) in the other images at the same geo-location. For applications that depend on a human to determine what the object is at a particular location, it is helpful to have multiple sensor types and for small targets, it is very helpful to have a cursor pointing at the exact same pixel(s) in the different images.
