This is a set of five photographs of CAPT James ‘Jim’ Leslie Stedman in the field demonstrating the setup of prisms used as electric distance measurement (EDM) receiver reflectors for tellurometer equipment and the sighting of a large surveyor’s light. This equipment was deployed in establishing mapping and geodetic control operations. The photos were most likely taken in the late 1950s or early 1960s. The tellurometers of this era were man-portable systems that improved geodetic survey efficiencies for rapid network extension and densification replacing triangulation with EDM and theodolite traverse sometimes using Bilby Towers to extend line lengths. Jim Stedman later reached the rank of Colonel, was Director of Military Survey from 1975 to 1978 and was appointed as Colonel Commandant (honorary appointment, Retd) of the Royal Australian Survey Corps from 1978 to 1983.
