Comments
2008-09 Future Coasts Victorian Bathymteric DEM and contour values across tile boundaries have been constructed to ensure smooth consistent bathymetry values. 
 
Missing Data
Comments
Voids exist in bathymetry values in shallow water areas due to the Lidar sensor unable to reach sea floor from factors such as wave break and turbidity.
