The Office of Security and Emergency Management, within the Department of Premier and Cabinet (DPAC) supports and responds to, emergencies arising from natural disasters and as such undertook to assess the impact of the winter 2016 flood event. A component of the assessment was to define the flood extent. The June 2016 HWM Flood Extent dataset was built from the June 2016 HWM Cross Section dataset. The June 2016 HWM Cross Section dataset was used to generate Triangular Irregular Network (TIN) Surfaces covering the required area of interest. This produces a TIN Surface of the HWM Flood Heights. The HWM TIN's were Converted to the Flood Raster HWM GRID Surfaces. The difference between the HWM Raster and DEM gives the areas of inundation, and the Extent of the Flooding. This extent was converted to Vector Data and polygonised. These polygons indicate the derived Flood Extent boundaries.
