Green Accumulation Index for New South Wales 1988-2012

Featuring a Landsat-derived map of green accumulation for New South Wales, Australia, analyzing the persistence of green vegetation following greening events. It was created from satellite imagery spanning 25 years, from 1988 to 2012. The data provides fractional cover information for bare ground, green vegetation, and dead vegetation per pixel.

Use Cases

• Analyze the duration of green vegetation persistence after rainfall events using the green accumulation index for drought monitoring.
• Map areas with high green cover values to identify potential habitats for native species or near-surface water sources.
• Study long-term vegetation response patterns across New South Wales by comparing green fraction data from 1988 to 2012.

Strengths

• Data spans a 25-year time range from 1988 to 2012, enabling long-term trend analysis.
• Derived from Landsat satellite imagery, providing consistent, remotely-sensed geospatial data.
• Provides pixel-level fractional cover for three distinct components: bare ground, green vegetation, and dead vegetation.

Limitations

• The dataset is temporally stale, with the latest imagery from 2012, limiting analysis of recent conditions.
• Specific technical details like spatial resolution, row count, and column structure are not provided in the input.
• Available file formats (HTML, PNG, TXT, PDF) suggest the primary data may be presented as reports or images rather than a structured, machine-readable table.
