With respect to the 83 onshore data, the Defence Imagery and Geospatial Organisation (DIGO) supplied the 84 DTED (Digital Terrain Elevation Data) Level 2 data which 85 has been authorised for Australian Tsunami Warning System use only. This data has a resolution of 86 1 second (about 30 metres), produced from 1:50 000 contours, elevations and drainage. 87 The Department of Land Information (DLI) has provided a 20m DEM and orthophotography 88 covering the NW Shelf. This data set is not bare earth and as a result, we have 89 chosen to use the 30m DTED Level 2 data due to its bare earth thingo. 85 A number of sources have supplied data for these two studies.

The Australian Hydrographic Office fairsheet data has also been utilised. 97 98 The coastline has been generated from the DIGO DTED2 and modified using the aerial photography and the two detailed 99 surveys provided by WA Department of Planning and Infrastructure.
