5028 Block 2 (Southeast) Grid of the Digital Elevation Model (DEM) derived from the radar altimeter and GNSS

A Digital Elevation Model (DEM) is a 3D representation of terrain elevation. It is derived from the radar altimeter and GNSS on the Survey aircraft. The GNSS height measurements are geoidal values derived using the Australian Vertical Working Surface (AVWS). This survey was acquired under the project No. 5028 for the Geological Survey of Western Australia (GSWA). The grid has a cell size of 0.000204 degrees (approximately 20m). The data are given in units of meters.
