In Image Analyst, the height (z-value) of the stereo cursor can be changed by rotating the mouse wheel. I use a standard mouse. When I rotate the wheel one notch, the height interval of the stereo cursor is as follows:
- approximately 0.5 meters on some ADS images
- approximately 1 meter on other ADS images
- approximately 2 meters on Ultracam frame images
I haven't found out why the above intervals are different, and what influences these intervals.
