Period

c. 1960s- early 1990s.

Canada

Element of A8 plotter used in Canada's national mapping program c. late 1960s-early 1990s, and an example of the last analogue plotting devices used by the Topographic Service of Canada. With the exception of the Wild A10 [few of which were used in Canada], this machine was the most sophisticated plotter available before digital technology. This plotter was converted c. 1995-96 to digitize the motions (X,Y & Z) with the addition of encoders and a control pad which interfaced to a computer. The Kern encoders and control module were installed by Terra Surveys of Ottawa when they rented this machine for the MOM project, completing the large scale mapping of Riyad, Saudi Arabia. The A8 was on loan to Terra for the duration of the project's digital compilation stage. [Ref. 1]

Function

To secure selected image [aerial photograph or negative] within plotter.

Technical

One of two image or picture carriers supplied and used with plotter. Identical to picture carriers for A7 Universal Autograph, facilitating movement of mounted images directly from one machine to the other: as the two plotter models were often used within the same facility, this greatly facilitated operations and was an attractive feature. [Ref. 4, p. 50]
