Victorian Shoreline Profile Timeseries from 1930 to 2023

Shoreline profile timeseries from 1930 to 2023 across sites monitored by the Victorian Coastal Monitoring Program. Data includes short-term and long-term shorelines derived from UAV surveys, satellite imagery, and aerial photos, with vertical uncertainty for UAV DSMs estimated at 0.1 m. The dataset is provided by the Department of Energy, Environment and Climate Action and was last updated in June 2026.

Use Cases

• Modeling long-term coastal erosion trends based on shoreline data from 1930 to 2023.
• Comparing shoreline positions derived from UAV surveys (including vegetation) with those from the VCDEM (excluding vegetation).
• Assessing shoreline change uncertainty using the provided 1 m cross-shore uncertainty estimate for UAV DSMs.
• Analyzing mean annual mid-tide shoreline trends from satellite imagery for the period 1988 to 2021.

Strengths

• Covers a long temporal range from 1930 to 2023.
• Vertical uncertainty for UAV-derived Digital Surface Models is quantified at 0.1 m.
• Incorporates data from multiple sources: UAV surveys, the Victorian Coastal Digital Elevation Model (VCDEM), satellite imagery, and aerial photos.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The alongshore spacing of 30-m may be too low to define complex, small-scale shoreline features.
