100 Years of National Topographic Mapping Conference, Canberra 2011
- Video acquired by Owen Pappy Gyles during the 1968 Mapping Control Surveys in WA and supplied on DVD by Peter Langhorne. Note that there is no sound track.
Segment one shows the field party coping with the flooding around Muggon Homestead and segment two travelling and arriving by boat at the Houtman Abrolhos Group off Geraldton. It is difficult to identify all those personnel in these sequences but the field party comprised the following members; Peter Langhorne, David Roberts, Vic Bosnic, David Hutton, Peter Blake, Bob Goldsworthy, Ed Ainscow, Ted Rollo, Owen Gyles, Les Dawson, David Ireland, Don Girvan, David Lewington, H. Hodge, John Weller, John Patrick, L. Marden and V. Elias.
- Video acquired during the 1969 Groundmarking for Aerodist field season.
Due to the cost, having a movie camera in the field was a rare occurrence. During the 1969 Groundmarking for Aerodist field season, however, Oystein Berg captured some of the different aspects of the field work that year on his movie camera. Thanks to Oystein a selection of short sequences have been extracted and may be selected and viewed here . Note that there is no sound track.
- Deal Island is the largest of the Kent Group of islands in Bass Straight. In the early summer of 1952 and later in early 1953, Deal Island was occupied by National Mapping's Reg Ford and an assistant to undertake the Bass Strait Triangulation which linked the geodetic surveys on the mainland with those on Tasmania. On both occasions, the Deal Island party was transported by the mailman on his regular run from Port Albert, Victoria. After being landed at the jetty at East Cove, the climb to the Deal Island Lighthouse took some 5 to 6 hours, the summit being almost 1,000 feet above sea level. While the Deal Island Lighthouse made a fine observing target it could not be used as an observing platform. The station mark for observing on the peak was thus some 680 feet from the lighthouse which was on a slightly lower peak. It was then necessary to measure down through a steep gully and up the other side to the centre of the lighthouse, and also read the required angles so that the calculation of the correction for the eccentric light could be made. During this survey, the line Deal Island back to Mount Fatigue, Victoria, was the longest observed at almost 84 miles (130 kilometres approximately). Now living outside of Yarram, Victoria, ex-Natmapper Laurie Edebohls became interested in this bit of history and arranged a flight over Deal Island in July 2017. This short (about 3 minutes) video (no audio) was acquired by him during the flight.
