Zoom Transfer Scope.
Abstract
This report covers the acceptance and engineer design tests and evaluation of the Zoom Transfer Scope, an instrument designed primarily for map revision, map completion, and map compilation. The report concludes that:--(1) with the exception of the frame design and slight reduction in achieved resolution at the higher magnifications, the instrument meets or exceeds the requirements of the technical characteristics; (2) the Zoom Transfer Scope appears to be an excellent instrument for many planimetric compilation and map revision operations when using vertical or near vertical frame photography; (3) in the stereoviewing mode, the Zoom Transfer Scope provides a means for limited contour compilation and intensification and permits a comparative analysis of a wide variety of photographic products, and (4) because of the severe reduction in the usable field of view, the instrument is not as beneficial for rectification purposes as originally envisioned, particularly when photographic inputs with tilts of 15 degrees or more are used.
