VCMP Sites - Shoreline Trends: Victorian Coastline Change 1988-2021

34 years of shoreline change data from 1988 to 2021, collected along Victoria's coastline. The dataset features short-term trends from drone surveys and long-term trends from satellite imagery, processed to a 30-meter transect framework. It is produced by the Victorian Coastal Monitoring Program under the Department of Energy, Environment and Climate Action.

Use Cases

• Modeling coastal erosion risk based on linear regression trends at 30-meter transects.
• Comparing short-term drone-derived shoreline changes with long-term satellite trends.
• Assessing horizontal uncertainty in shoreline position for different data sources and time periods.

Strengths

• Horizontal-vertical uncertainty of 0.1 m or better for drone survey outputs.
• Long-term trends cover a 34-year period from 1988 to 2021.
• Standard deviations and 95% confidence intervals are included for each data point.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Older aerial images (pre-2000) can have horizontal uncertainty estimated at up to 10-m.
