Drainage Basin Polygons for Greater Geelong

Greater Geelong municipality's dataset contains polygon features for all man-made 'wet' and 'dry' drainage basins. The City of Greater Geelong created and maintains this dataset, which was last updated in April 2026. It provides the geographic boundaries and hydraulic function classification for these engineered water management structures.

Use Cases

• Classify basin types ('wet' vs 'dry') using polygon attributes for hydraulic function analysis.
• Calculate total catchment area coverage by summing polygon geometries for stormwater capacity planning.
• Assess spatial distribution of man-made basins by analyzing polygon locations relative to urban features.
• Integrate basin polygon layers with other geospatial data using the GCS_WGS_1984 coordinate system for comprehensive environmental modeling.

Strengths

• Polygon data covers all drainage basins within the entire Greater Geelong municipality.
• Includes classification of basins by hydraulic function ('wet' vs 'dry').
• Data is provided in multiple standard geospatial formats (GEOJSON, SHP, WFS, WMS).

Limitations

• Unknown total row count for basin features.
• No temporal data range is provided for when basins were constructed or recorded.
• Limited to man-made basins, excluding naturally occurring waterbodies.
