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. {"type": "Polygon", "coordinates": [[[107.9979, -48.0021], [164.0021, -48.0021], [164.0021, -7.9979], [107.9979, -7.9979], [107.9979, -48.0021]]]} 107.9979 164.0021 -48.0021 -7.9979 Ausdrape Australia DEM EARTH SCIENCES Earth sciences Elevation GADDS2.0 NCI None Published_External airborne digital data geoid geophysical survey geophysics grid raster survey 202008 terrain File available for download in various formats from the GADDS2 portal documentDigital The Geophysical Archive Data Delivery System (GADDS2) portal provides HTTP download of geophysics datasets in a number of formats.
