A stereoscope in which a digitally stored image can be seen through either or both eyepieces and compared with an object which can also be seen through either or both eyepieces. Digital images of objects can be stored. Both the images to be stored and the stored images can be digitally manipulated, i.e. magnified, rotated or warped.

Soft copy port

A cartographic apparatus for determination of the elevations of features and heights of objects from stereoscopic images of complementing input records includes a parallax bar and movable reticles for generating a floating mark over points of interest in the records. The apparatus also includes a microprocessor to compute compensation factors based on values determined during initial set up and means responsive to those factors to compensate automatically for y parallax and for errors in x parallax difference as the floating mark is moved and to compute automatically object heights and feature elevations.
