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.

国家级地表水文多边形（Surface Hydrology Polygons (National)）数据集展示了地表水文多边形要素的空间位置及其属性信息。本数据集以国家尺度表征澳大利亚的地表水文特征，涵盖自然与人工地理要素，包括河道区域、沼泽、水库、运河等。本数据集所包含的水文多边形要素将与水文线要素实现拓扑关联，共同构建覆盖整个澳大利亚大陆的完整水流路径网络。
