Winter Irrigated Crop Areas in New South Wales from 1987 to Present

From 1987 to the present day, this dataset provides a time series of irrigated crop locations and extents during the winter season in New South Wales, Australia. It is derived from Landsat and Sentinel satellite imagery and updated on an ongoing basis for selected catchments. The data is produced by the NSW Department of Climate Change, Energy, the Environment and Water.

Use Cases

• Monitor changes in irrigated agricultural land use over time based on the multi-decade satellite time series.
• Analyze the spatial distribution of winter-season irrigation based on the polygon data.
• Assess water resource planning and policy impacts based on catchment-level irrigation data.
• Validate or calibrate hydrological models based on historical irrigated area extents.

Strengths

• Time series spans from 1987 to the present day, providing over 35 years of historical context.
• Derived from publicly available Landsat and Sentinel satellite collections, ensuring a reproducible methodology.
• Updated on an ongoing basis, suggesting current data for selected catchments.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au, focusing only on NSW catchments.
