Description

Lidar laser strikes have been classified into ground and non-ground using a series of algorithms tailored for major seafloor combinations across project areas. The quality of the classification is further improved by manual checking and editing of the seafloor Lidar using imagery as a reference.

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.
