David HillanThe author, David Hillan, became a registered Surveyor in NSW in 1952 and later in other States of Australia. During this time, he was engaged on a wide variety of surveys covering marking original country sections, townships, engineering surveys, ai photo control for map making, tunnel alignment surveys and reconnaissance for major projects. The work in marking out sections involved the search for blazed trees of early surveyors from the nineteenth and twentieth centuries. His work on photographic tunnel cross sections won a prestigious award in a professional journal in 1955. This technique has subsequently been used extensively overseas. In the mid-seventies he developed an original photographic survey method to determine flight paths of aircraft for the control of noise. A paper on this was presented to a Parliamentary Select Committee. He was involved in maritime search and rescue for more than thirty years and some of the techniques used in that activity have been utilised in this investigative research. In addition, he was an Olympian, having been section manager for his sport at the 1972 Munich and 1976 Montreal Olympic Games as well as manager of many other international teams. Read More Read Less
