Attribute_Accuracy_Report:

See the readme file in the download directory for full details on methodology used and descriptions of these data. The strain-grids were surveyed using Leica series 399 dual-frequency GPS receivers. The stop-and-go technique was chosen for this work as it provides a very efficient and relatively robust method for surveying large numbers of points in areas with good horizon visibility. The technique combines dual-frequency carrier phase data from a fixed receiver with those recorded by a roving receiver occupying discrete points (in this case the strain-grid markers). In the field reference receivers were set-up locally on the glacier surface for each survey due to the lack of nearby rock outcrop. Coordinates for the reference receivers were later computed using the AUSPOS online GPS processing service maintained by Geoscience Australia. AUSPOS imports raw data submitted via the internet and processes it differentially against a network of nearby permanent GPS sites in Antarctica (e.g. at Casey, Davis and Mawson). The AUSPOS derived coordinates were then used to provide fixed reference for the ensuing survey network adjustments (using least-squares) incorporating the stop-and-go baselines. This was accomplished by post-processing of the data using commercial GPS processing software. The relative precisions of the stop-and-go baselines are typically at the centimetre to sub-centimetre level (as shown in the spreadsheets). The absolute accuracies of the coordinates, however, would not be better than +/- 2cm in horizontal and +/- 5cm in vertical, accounting for the small accumulated errors of the fixed reference station that arise from: (i) precision of the AUSPOS output, and; (ii) centimetre to sub-centimetre movements of the reference station, on the slow-moving glacier platform, during the survey periods.
