A polygon layer of rectangular cells aligned to 5-minute increments of the GDA94 latitude/longitude graticule serves as an indexing mechanism for point record observations of flora and fauna. The layer covers southeast Australia from 139°E to 151°30'E and 33°S to 42°S, incorporating substantial areas of South Australia and New South Wales plus Bass Strait and Tasmania's north coast. It was published by the Department of Energy, Environment and Climate Action and last updated on April 9, 2026.
Use Cases
- Indexing flora and fauna point observations based on the 5-minute graticule grid.
- Aggregating biodiversity data into standardized spatial units based on the polygon layer.
- Mapping species distribution patterns across southeast Australia based on the defined geographic extent.
- Integrating ecological survey data with other geospatial layers using the consistent GDA94 coordinate system.
Strengths
- The geographic extent is precisely defined from 139°E to 151°30'E and 33°S to 42°S.
- The data is provided in multiple GIS file formats including DWG, MIF, DXF, SHP, TAB, and GDB.
- It uses the GDA94 coordinate reference system, a standard for Australian spatial data.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- The description metadata is limited; actual data quality requires manual inspection after download.
