Sentinel-2 Seasonal Ground Cover Fraction Estimates for Queensland

Giving access to seasonal fractional ground cover estimates for Queensland, derived from Sentinel-2 satellite imagery using the JRSRP algorithm version 3.0. It includes proportions of bare ground, green, and non-green ground cover at a 30-meter pixel resolution for each 3-month calendar season. The product is experimental and has not been fully validated.

Use Cases

• Analyze seasonal changes in bare ground, green, and non-green ground cover proportions to monitor land degradation.
• Estimate persistent green vegetation fraction to identify areas of woody vegetation cover over time.
• Compare ground cover estimates in areas with less than 60% woody vegetation to assess pasture or crop health.
• Integrate the 30-meter resolution fractional cover rasters with other geospatial data for land management planning.

Strengths

• Provides spatially explicit raster data at a medium resolution of 30 meters per pixel.
• Separates persistent green vegetation from seasonal ground cover, enabling more accurate estimates.
• Covers the entire state of Queensland, offering regional-scale environmental data.

Limitations

• Ground cover estimates become uncertain in areas with more than 15% tree cover.
• The product is experimental and has not been fully validated, which may affect reliability.
• The persistent green component is derived from 30-meter Landsat data, limiting the final Sentinel-2 product's resolution.
