Shallow Inlet Seagrass Meadows: Spatial Extent and Density from 1999

Shallow Inlet Seagrass 1999 is a geospatial polygon dataset mapping the extent, species distribution, and density of seagrass meadows in Shallow Inlet. The data was created by the Victorian Fisheries Authority from 1999 aerial photography and ground-truthing. It was last updated on the platform in April 2026.

Use Cases

• Map historical seagrass meadow extent based on the described spatial polygons.
• Analyze species distribution patterns within the mapped seagrass beds.
• Assess habitat density for ecological modeling based on the described density attributes.
• Establish a 1999 baseline for studying changes in coastal vegetation over time.

Strengths

• Data is derived from aerial photography combined with ground-truthing, suggesting a validated mapping method.
• The dataset has a clear temporal anchor from 1999.
• Available under a permissive CC-BY-4.0 license for reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified as the underlying data is from 1999, despite a 2026 platform update.
