Victorian Coastal Digital Elevation Model 2021 (VCDEM): 10m Resolution Bathymetry

A 10-meter resolution Digital Elevation Model (DEM) for the Victorian coast, integrating new bathymetric datasets to update versions from 2017 and 2010. The dataset, produced by Veris for the Department of Energy, Environment and Climate Action, includes both high-resolution and seamless gridded outputs. It serves as a foundational product for the Victorian Coastal Mapping Program to improve understanding of dynamic coastal processes and risks.

Use Cases

• Model coastal inundation and sea-level rise impacts based on high-resolution elevation and bathymetry.
• Analyze coastal erosion and sediment transport patterns based on the seamless topographic-bathymetric surface.
• Assess coastal habitat changes and vulnerability based on the integrated elevation model.
• Support marine spatial planning and infrastructure risk assessment based on the foundational coastal mapping data.

Strengths

• Gridded spatial resolution equal or superior to 10 meters.
• Vertical uncertainty meets IHO Order 1b specifications, which is better than 0.5 meters.
• Integrates new bathymetric datasets not present in the 2017 and 2010 versions.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The high-resolution product contains gaps where data does not meet the 10m/0.5m specifications.
