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]

Technical

Largest of 3 plotting table sizes available for use with A8, the 110 x 140 cm plotting surface was recommended for mapping at large scales. (Ref. 4)
