Agricultural Dam Boundaries in Western Australia

Over 175,000 agricultural dams in Western Australia are mapped in this dataset. It was created by the Department of Primary Industries and Regional Development using deep learning segmentation on 2018-2019 satellite imagery.

Use Cases

• Analyze dam distribution and density across Western Australia for agricultural water resource planning.
• Use spatial boundaries to assess irrigation infrastructure proximity to farmlands.
• Filter dam features using the applied deep learning binary classifier methodology for quality control.
• Integrate dam boundaries with other waterbody datasets for comprehensive hydrological modeling.

Strengths

• Contains over 175,000 mapped dam features.
• Features were re-extracted at a higher resolution than previous versions.
• Derived from Vivid 2.0 satellite imagery captured mostly from 2018 to 2019.

Limitations

• The dataset's spatial accuracy is dependent on the resolution of the source satellite imagery.
• Temporal coverage is limited primarily to a 2018-2019 snapshot, which may not reflect recent changes.
