Castlereagh River Digital Elevation Model
The Castlereagh River 5m Digital Elevation Model (DEM) is generated from all relevant data available on the Elvis - Elevation and Depth - Foundation Spatial Data (Elvis) platform with a resolution of 5 Metres or higher. Source datasets with a resolution higher than 5m have been resampled to 5m. This elevation model is generated using 5011 datasets from a total of 5760 datasets sourced from multiple providers including State and Territory Governments. The capture dates for input data range from 24/04/2011 - 09/05/2017. See Table 1 below for further information. The area covers the land mass of the Castlereagh River drainage basin as defined by the Bureau ofMeteorology Geofabric.

<div>A 10m buffer was applied to the extent of the drainage basin to ensure overlap with neighbouring basins.</div><div>Datasets available in the Elvis platform that intersected the buffered basin area were downloaded. Where</div><div>multiple datasets overlapped, the cell value from the most recently captured data was used. As required,</div><div>individual tiles were resampled to 5m resolution, reprojected to GDA2020 and aligned to the whole 5m grid</div><div>value to ensure cell alignment between datasets. Nearest neighbour resampling method was used for each</div><div>of these steps. Tiles were then mosaicked to form a single raster output. In some areas small holes were</div><div>present in the mosaicked product due to the input tiles not aligning or overlapping completely. Data gaps</div><div>less than or equal to 15m (3 cells) were filled by interpolation. Cells within larger data gaps were assigned</div><div>“no data” values in the output mosaic.</div>
