National Surface Hydrology Polygons of Australia

The dataset represents Australia's surface hydrology at a national scale. It includes natural and man-made geographic features such as watercourse areas, swamps, reservoirs, and canals. These polygon features topologically connect with hydrology line features to form a complete flow path network for the entire continent.

Use Cases

• [Modeling continental water flow] based on [a topologically connected flow path network]
• [Mapping man-made water features] based on [polygons for reservoirs and canals]
• [Assessing wetland extent] based on [polygon features for swamps]
• [Analyzing watercourse areas] based on [national-scale hydrology polygons]

Strengths

• Provides a complete national-scale representation of Australia's surface hydrology.
• Includes both natural and man-made water features, enhancing utility for diverse applications.
• Features are topologically connected to form a continental flow network, supporting hydrological modeling.

Limitations

• Specific column names, row counts, and data size are not provided in the source metadata.
• The listed last update date of 2026-04-30 appears to be a future date, which may indicate a data entry error or placeholder.
• License and author information are not specified, which may restrict clarity on usage rights.
