CTH Surface Hydrology Polygons (National)
The Surface Hydrology Polygons (National) dataset presents the spatial locations of surface hydrology polygon features and its attributes. The dataset represents the Australia's surface hydrology at a national scale. It includes natural and man-made geographic features such as: watercourse areas, swamps, reservoirs, canals, etc. This product presents hydrology polygon features which will topological connect with the hydrology line features and forms a complete flow path network for the entire continental of Australia.
The Surface Hydrology Polygons (National) dataset is a collaborative effort by Geoscience Australia and state governments. Geoscience Australia has conflated a 1:250,000 national digital surface hydrology dataset from and aggregated best available jurisdiction dataset. This dataset contains the hydrology polygon features only.
