VCMP Sites - Shoreline Timeseries: Victorian Coastline Data 1930-2023

Shoreline timeseries data from the Victorian Coastal Monitoring Program spans from 1930 to 2023 across sites along Victoria's coastline. The dataset includes short-term and long-term shorelines derived from multiple sources, including UAV surveys, satellite imagery, and aerial photography. It is provided by the Department of Energy, Environment and Climate Action.

Use Cases

• Analyze long-term shoreline change trends based on data from 1930 to 2023
• Compare shoreline positions derived from different methods like UAV DSMs, satellite imagery, and aerial photos
• Assess cross-shore uncertainty in shoreline position based on the described vertical uncertainty and beach slope assumptions
• Model coastal erosion and accretion patterns using the time-series of shoreline proxy and backshore lines

Strengths

• Covers a long temporal range from 1930 to 2023
• Integrates multiple data sources including UAV surveys, satellite imagery (DEA), and aerial photography
• Provides specific vertical uncertainty estimates for DSMs (0.1 m) and horizontal uncertainty for newer aerial images (3 m or less)
• Includes a defined shoreline proxy based on specific contour levels (1.0 m AHD for open coasts, 0.5 m AHD for bays)

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 as noted
