Brief description

The Richmond 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 from 1972 datasets sourced from multiple providers including State and Territory Governments. The capture dates for input data range from 19/03/2010 - 15/09/2015. See Table 1 below for further information.

The area covers the land mass of the Richmond River drainage basin as defined by the Bureau of Meteorology Geofabric. Near shore bathymetry data has also been included in the final raster.

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

Near shore bathymetry datasets were downloaded from the Elvis platform and mosaicked into a single bathymetry raster. The bathymetry and terrestrial area outputs were then mosaicked to form a single product covering both the terrestrial area and near shore bathymetry. In instances of overlap between the two, cell values from the terrestrial dataset were used in the resulting DEM.

Data has been sourced from the captures and custodians listed in Table 1.
