1997 aerial photography and field observations were used to map the spatial extent, species distribution, and density of seagrass and submerged aquatic vegetation in the Gippsland Lakes. The dataset is provided by the Victorian Fisheries Authority and was last updated in April 2026. It is available in multiple GIS formats including DWG, MIF, DXF, SHP, and TAB.
Use Cases
- Analyze seagrass spatial extent based on mapped polygons
- Study species distribution patterns based on identified vegetation types
- Assess habitat density based on field observation data
- Create GIS overlays for environmental planning based on the geospatial layer
Strengths
- Data is derived from both aerial photography and field observations, suggesting a multi-source validation approach
- Available in seven GIS file formats (DWG, MIF, DXF, SHP, EXTENDED TAB, GDB, TAB), offering flexibility for different software
- Last updated in April 2026, indicating metadata maintenance
Limitations
- Row count is unknown, which may limit suitability assessment
- Column-level documentation is absent; field semantics must be inferred after download
- Data is from a single year (1997), limiting temporal analysis
