Title: TESTS AND EVALUATION OF AN EARTH CURVATURE CORRECTION DEVICE
|
||
|
|
Subject: Tests and evaluation were made of an internally developed Earth Curvature Correction Device for use with an anaglyphic projection-type stereo plotter in military mapping. Tests of the device were carried out on the High Precision Military Stereoplotter. The report presents evidence of the state of calibration of the plotter, the flatness of a steroscopic grid model, and the accuracy of the curved surface developed by the correction device when compared to computed va The corrections were measured by elevation readings in a grid model with the device in operation and by dial gauge readings referenced to the plotter table.
