Function

TO PROJECT STEREOSCOPIC MODEL IN ORDER TO INTERPRET, MEASURE & PLOT DATA GATHERED FROM AERIAL SURVEY PHOTOGRAPHS.

Technical

DESIGN PERMITS A CLOSE-SPACED PATTERN OF LUMINOUS DOTS TO BE PROJECTED & FORMS AN ELEVATION REFERENCE PLANE IN THE STEREOMODEL. THE 2 PROJECTORS ARE RAISED OR LOWERED IN UNISON, MOVING MODEL DATUM WITH RESPECT TO THE REFERENCE PLANE. CONTOURS & PLANIMETRIC DETAIL ARE TRACED FREEHAND ON MAP SHEET ON TABLE BELOW (REF.1) "The Gamble stereoplotter was designed by Samuel G. Gamble, Dept. of Mines & Technical Surveys, Canada, & mfd. by PSC Applied Research Ltd., of Toronto, Canada. This instrument utilizes either multiplex or Balplex projectors to form the stereomodel in anaglyphic projection. A very close-space pattern of luminous dots is projected to form an elevation reference plane in the stereomodel. Raising & lowering of the projectors in unison moves the model datum with respect to the projected elevation reference plane. Contours & planimetric detail are traced freehand on a map sheet mounted directly upon two supporting tables. The handheld tracing pencil thus becomes the floating mark in the projected model."
