AUSGeoid98 v.1.0 data files: Cambridge Gulf (sd52-14)
Dataset Identification:
Resource Abstract:
AUSGeoid98 data files contain a 2 minute grid of AUSGeoid98 data covering the Australian region, which you can use to interpolate
geoid-ellipsoid separations for the positions required.You can use your own interpolation software, or you can use Geoscience
Australia's Windows Interpolation software (Winter). The data files are text files in a standard format that cover the same
area as standard topographic map areas. Files covering both 1:250,000 (approximately 100 x 150 km) and 1:1,000,000 (approximately
400 x 600 km) map areas are available. There is a 4 minute overlap on all sides of each area. Data format: AUSGeoid98 data
files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98
data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only
2 decimal places. AUSGeoid98 deflections of the vertical were computed from the geoid-ellipsoid separation surface, while
the AUSGeoid93 deflections of the vertical were computed from OSU91A.
