| Abstract: | The Canadian government's imaginative approach to fostering scientific excellence produced an environment ideal to draw the very best from Uki Helava's fertile intellect when he joined the Photogrammetric Section, Division of Physics, NRC, Ottawa in 1953. Initial work on error control in aerial triangulation led into the design of instruments for image measurement. This work culminated in the production of the NRC Monocomparator, but Helava's main effort was devoted to the analytical plotter, for which a working model was exhibited in 1963. Difficulties with the commercialization of this device led to Helava's decision to leave NRC in 1965. |
