Irrigated Crop Areas in NSW Derived from Satellite Imagery, 1987-Present

A spatial dataset provides a time series of irrigated crop locations and extents in New South Wales, Australia, derived from Landsat and Sentinel satellite imagery. It is produced by the NSW Department of Climate Change, Energy, the Environment and Water and covers data from 1987 to the present day. The product includes separate datasets for summer and winter irrigated crop areas.

Use Cases

• Tracking changes in irrigated agricultural land use over time based on the 1987-present time series.
• Comparing seasonal irrigation patterns between summer and winter crop areas.
• Analyzing the spatial distribution of irrigation within selected NSW catchments.

Strengths

• Time series spans from 1987 to the present day, offering long-term trend analysis.
• Data is derived from multiple satellite sources (Landsat and Sentinel), likely improving temporal resolution.

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.
