Seasonal Persistent Green Vegetation Estimates for Australia via Landsat

Supplying seasonal estimates of persistent green vegetation cover across Australia, derived from Landsat imagery using the JRSRP algorithm. It has been superseded and will not be processed from early 2023, with an updated version available. The dataset is provided in HTML, PNG, and TXT formats.

Use Cases

• Analyze seasonal patterns of persistent green cover to study woody vegetation dynamics across Australia.
• Use the derived time series of green fraction to model vegetation phenology and its response to climate.
• Apply geospatial analysis to the PNG outputs for mapping regional variations in non-senescing vegetation cover.
• Compare seasonal estimates of persistent green cover to identify areas where non-woody vegetation remains green year-round.

Strengths

• Derived from Landsat satellite imagery, a consistent long-term data source.
• Focuses on persistent green cover, a specific metric for woody vegetation analysis.
• Covers the entire continent of Australia, providing national-scale geospatial data.

Limitations

• The product has been superseded and will not be updated after early 2023, limiting its use for current analysis.
• The specific data volume, row count, and column structure are unknown.
• Available file formats (HTML, PNG, TXT) may require processing for quantitative analysis compared to structured raster formats.

Collection Method

Derived by fitting a multi-iteration minimum weighted smoothing spline through the green fraction of the seasonal fractional cover time series from Landsat.

Freshness

Last updated metadata indicates 2026-03-20, but the data product itself is discontinued from early 2023.
