Discussion took place on the benefit in assembling a complete accessible archive of these early GPS epoch campaigns to encourage use of the data by researchers to compute independent results. In addition to data from the epoch campaigns, Mr Mullins added that GPS data from the South Pole station for a number of periods was archived at USGS Reston and was available for research use.
A delay had been encountered in receiving data from the Great Wall station but the full data set was being assembled and about 70% of the data had been collated so far. The following five groups would then analyse the data using different software approaches ie:
Links to tide gauges had been made at a number of sites :
The meeting complimented Germany on the success of the field campaign and looked forward to seeing the results of the analysis at the Cambridge meeting, perhaps as a special symposium session.
Reference to some publications arising from SCAR EPOCH Campaigns
In addition to access to the data from the SCAR EPOCH GPS campaigns of temporary occupations, the trend world wide was to establish permanent GPS trackers. This was the case in Antarctica and Rogue receivers were now operating at the following sites :
To clarify the situation at McMurdo, Mr Shupe gave an illustrated presentation of the history of the McMurdo GPS sites and also the Ashtech receivers at the South Pole.
The meeting agreed that a geodetic information outlet should be put up on the WWW possibly under a SCAR Working Group on Geodesy and Geographic Information home page. It was considered timely to prepare a full history of the permanent GPS sites and to identify access to data being collected and archived.
The meeting was sympathetic but indicated that at this stage the focus on the GIANT program was to establish a geodetic infrastructure of precise points around the Antarctic continent at the sub metre level. This would then be used to bring all surveys onto the one datum or reference frame. Such an integration of surveys was still a long way into the future. At this stage each nation held its own geodetic records and image or photo idents for ground survey points were usually made so that the information could be used for mapping. In some areas it would now be possible to use photogrammetric points to produce good image points such as with the recent GPS controlled aerial photography of the dry valley areas by the co-operative USA/NZ projects.
Dr Kieffer distributed a proposal outline which he had submitted to NASA seeking support to establish a Polar Ground Control Point Library consisting of digital image chips surrounding a survey control point. The meeting indicated that the GIANT program was one of a number of programs undertaken by the Working Group on Geodesy an Geographic Information and that Dr Joern Sievers was the convenor of a similar program looking at the use of satellite imagery in Antarctica. Mr Manning said he would correspond with Dr Sievers initially as he is the appropriate person for Dr Kieffer to discuss his proposal.
Mr Mullins introduced Dr D. McAdoo, chief Geodynamics Branch of the NOAA Geosciences Laboratory who was arranging to take a FG5 to the McMurdo area in the 1995/96 summer. Dr McAdoo proposed observations at a number of sites to minimise the disadvantages of the immediate McMurdo base area, possible sites were :
Dr Grant pointed out the desirability of observing at least one site in New Zealand during transit of the instrument through New Zealand. Mr Manning also raised the possibility of flying it across the Tasman to the VLBI/GPS site in Hobart.
Mr Manning later circulated Table 1 as a draft Absolute Gravity program and invited comment.
