Abstract
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.
