Victorian Coastal Digital Elevation Model 2021 (VCDEM) - 250cm

Victoria, Australia's coastal elevation and bathymetry data, updated in 2021 by integrating new datasets. The dataset is foundational to the Victorian Coastal Mapping Program and is produced by Veris. It includes high-resolution and seamless gridded outputs with a spatial resolution equal to or better than 10 meters.

Use Cases

• Model coastal erosion and inundation based on high-resolution elevation and bathymetric data.
• Analyze seafloor topography for marine habitat mapping based on the integrated bathymetric datasets.
• Improve hydrodynamic and sediment transport models based on the seamless elevation product.
• Assess coastal infrastructure vulnerability based on the updated digital elevation model.

Strengths

• Spatial resolution is equal to or superior to 10 meters for both major outputs.
• 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.
• Available in multiple common geospatial file formats including TIFF, GEOTIFF, and JPEG 2000.

Limitations

• The high-resolution product contains gaps where data does not meet the 10m/0.5m specifications.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total dataset size are unknown, which may limit suitability assessment.
