See the report for further information. The values provided in spatial coverage are approximate only. Remarks Aerial Photography This is the latest of many unsuccessful attempts at acquiring aerial photography of Macquarie Island. If aerial photography is to be considered a priority for the Mapping Program's support of the scientific community it is evident that a different approach is required. Attempting to acquire a systematic coverage during a three to four day re-supply visit is unrealistic owing to the short time frame, emphasis on cargo operations and generally poor weather conditions. Other options put forward by Noel Ward in January this year are: - Leave a suitably equipped aircraft on the island for a short summer season - During a short ship visit place one aircraft under the control of the mapping program so that cargo operations cannot compromise attempts at aerial photography - Engaging a contractor to acquire photography on a pay on results basis Because of the weather conditions it is unrealistic to expect to be able to acquire photography of the whole island in one mission during a re-supply visit. The aircraft is required for cargo operations and it takes about 1-2 hours to equip the helicopter. If an aircraft were equipped and dedicated to the aerial photography it may be possible to photograph the island 'bit by bit' as the weather allows. To improve response time most of the camera equipment could be permanently pre-fitted to the rack and a full wiring harness developed. This would reduce the time it takes to fit the camera equipment into the helicopter, enabling a faster response when weather conditions become suitable for aerial photography. GPS Problems at Hurd Point Problems with the Leica GPS equipment prevented the measurement of the baseline from the Aurora Camera Stand NMX1 to Hurd Point Trig NMX7. These problems may have been avoided if the surveyor, Frank Hoogesteger, had had the opportunity of testing the equipment prior to the departure of voyage 3. Taken from sections of the report: Introduction This report details the survey work carried out on Macquarie Island during November and December of 1996 by the Australian Surveying and Land Information Group (AUSLIG) on behalf of the Australian Antarctic Division's Mapping Program. The principle aim of the program was to acquire aerial photography to enable the production of a new topographic map of the island. A number of other tasks were also required to be carried out. This report deals with each task and the results achieved. The survey work was carried out by the following people: Frank Hoogesteger - Tasmanian Department of Environment and Land Management Roger Handsworth - Platypus Engineering Richard Lemon - Australian Surveying and land Information Group Although this report touches on the work carried out by Roger Handsworth and Frank Hoogesteger, it does not cover the specifics of their work, that being the subject of separate reports to be submitted the them. Time Frame The Macquarie Island field party departed Hobart at about 5pm on Monday 25th November 1996 aboard the Aurora Australis, voyage 3 of the ANARE re-supply season. Voyage 3 arrived at Macquarie Island at about 9am eastern standard summer time (UT+11) on Thursday 28th November. The survey party departed Macquarie Island at about 10am on Monday 2nd December and arrived back in Hobart at about 7am on Thursday 5th December 1996. This provided three and a half days on the island in which to complete the survey program. Aims and Project Brief The 1996/97 Survey Program for Macquarie Island lists the following tasks and those responsible for their execution: 1. Aerial Photography of the island and station area (Lemon/Handsworth) 2. Precise leveling from AFN station, AUS211 RM1 and RM2 to Garden Cove Bench Mark AUS228 (Lemon) 3. Field survey of station buildings and services to check and update Digital Station Information System (Lemon) 4. Install tide gauge staff and carry out water level observations at Garden Cove (Handsworth/Lemon-assist) 5. GPS baseline from the AFN Station AUS211 to the Garden Cove Tide Gauge Bench Mark AUS92 (Lemon) 6. Retrieval of corner cube reflectors for use on Heard Island (Lemon) 7. Re-establish the Management Zone boundaries and identify to the new Station Leader (Hoogesteger) 8. Level connection by GPS from the aurora camera stand NMX1 to Hurd Point Trig. NMX7 (Hoogesteger) 9. Level connection by EDM from Hurd Point Trig NMX7 to tide gauge sensor (Hoogesteger) 10. Download data and Check Hurd Point Tide Gauge. Install temporary tide staff at Hurd Point and take water level and temperature readings (Hoogesteger) 11. Carry out maintenance of the tide gauges at Garden Cove (Handsworth) 12. On an opportunity basis check height and position of features on the plateau for ground truthing of SAR DEM (Lemon) These tasks are listed in order of priority.
