Gippsland 1" digital elevation model clip GA

## **Abstract** \n\nThe dataset was derived by the Bioregional Assessment Programme from the Geoscience Australia, 1 second SRTM Digital Elevation Model (DEM). The parent dataset(s) is identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.\n\n\n\nThis dataset shows the elevation of the land surface in metres. The 1" SRTM Digital Elevation Model (GA) has been clipped to the 2015 Gippsland region groundwater model (Beverly , 2015). This dataset was reused in the Bioregional Assessment Programme without modification.\n\n## **Purpose** \n\nThis dataset shows the elevation of the land surface in metres.\n\n## **Dataset History** \n\nThe data was obtained from the 1 second (\\~30 m resolution grid cell) Shuttle Radar Topography Mission (SRTM).The STRM global elevation data was collected by Space Shuttle Endeavour during eleven days in February 2000. The data was acquired by interferometric synthetic aperture radar based on interference patterns between radar signals collected by two antennas. The Shuttle was oriented to point the antennas at 45° to the ground to optimise the effect of topography on the interference patterns.Obscured regions such as zones of large topographic variation were evaluated by collecting overlapping swathes from different orbits.\n\n\n\nThe Gippsland Regional Model Extent (8e56c1ca-3fe9-4eb6-9ac0-75ba3f4058f8) was used to extract the Model clip from the SRTM data.\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (2000) Gippsland 1" digital elevation model clip GA.
