dc.description.abstractThe application of the digital computer has been extended to include the analysis of analog records. Cartographic data, a highly sophisticated form of analog record, must be digitized by suitable devices for the development of an Automatic Cartography System. This thesis describes the results of tests performed on one such digitizer and the feasibility of a proposed improvement. The low cost, position-sensing servomechanism of the Pencil Follower manufactured by d-mac Company Ltd., exhibits characteristics which were undesirable when digitizing maps and charts; namely lag, inconsistent resolution, and poor lock-on. The feasibility of replacing the servomotor drive with a stepper motor drive was investigated, with the necessary circuitry developed and tested. Preliminary tests were performed on a one axis model to verify the proposed melioration.en_US
