National Gravity Compilation 2019 Ausdrape elevation geoid grid
Digital Elevation data record the terrain height variations from the processed SRTM surface elevation 3 second grid data with a drape surface overlain. This National Gravity Compilation 2019 Ausdrape elevation geoid grid is elevation data for the 2019 Australian National Gravity Grids B series. These data are used in the project No. 202008. The grid has a cell size of 0.00417 degrees (approximately 435m). All data (i.e., ground, airborne and marine derived from satellite altimetry) were vertically continued to this surface during processing. The surface was generated to mimic a smooth airborne survey drape surface with a minimum surface clearance of 250 m and an isotropic maximum climb and descent rates of 25 m per km. The ground surface data were derived from SRTM data with 3 second grid cell size. The data are given in units of meters. The data are given in units of meters.

- Statement
-
This National Gravity Compilation 2019 Ausdrape elevation geoid grid contains the elevation data for the 2019 Australian National Gravity Grids B series (Lane et al., 2020a) relative to the geoid vertical datum. These data are used in the project No. 202008. The grid has a cell size of 0.00417 degrees (approximately 435m). All data (i.e., ground, airborne and marine derived from satellite altimetry) were vertically continued to this surface during processing. The surface was generated to mimic a smooth airborne survey drape surface with a minimum surface clearance of 250 m and an isotropic maximum climb and descent rates of 25 m per km. The ground surface data were derived from SRTM data with 3 second grid cell size (Gallant et al., 2011; CGIAR-CSI, 2019). The data are given in units of meters. Details of the processing steps used in the generation of this surface and its relationship to the data processing can be found in Lane et al. (2020b). The processed data are checked by GA geophysicists using standard methods for assessing quality to ensure that the final data are fit-for-purpose.
