Seasonal Fractional Cover Summary Statistics - Sentinel-2, JRSRP Algorithm Version 3.0, Queensland Coverage
These Seasonal Fractional Cover Summary Statistics datasets provide long-term statistical summaries derived from the <a href=" https://portal.tern.org.au/metadata/TERN/13810293-c6b5-442b-bfcd-817700738e0d ">sentinel2-based seasonal fractional cover v3 product</a>, calculated separately for each fraction.
<br></br>
For each cover fraction, a separate raster image is generated for the full time series of available imagery. Each image includes the following statistical layers: 5th percentile (minimum), Mean, Median, 95th percentile (maximum), Standard deviation and Observation count.

- Purpose
- These products display the variation of the sentinel2 seasonal fractional cover fractions over long term temporal periods (e.g. 2017-2024). They are based on the JRSRP Fractional Cover v3.0 algorithm.

- <p>1) All the data described here has been generated from the analysis of Sentinel-2 data, which has a spatial resolution of approximately 10 m in the Blue, Green, Red and Near Infra-red (NIR) bands, and 20 m in the two Short Wave Infra-red (SWIR) band. The 20 m bands have been resampled to 10 m using cubic convolution, to provide a consistent 10 m data set. The imagery is rectified during processing by the European Space Agency (ESA), and not modified spatially beyond that.<br />2) The fractional cover model was compared to samples drawn from approximately 4000 field reference sites.</p>
Report
Result
- Statement
- <p>1) The Sentinel-2 Data Quality Report from ESA indicates that positional accuracy is on the order of 12 m.</p> <p>2) The fractional cover model predicts the vegetation cover fractions with MAE/wMAPE/RMSE of:</p> <ul> <li>bare - 6.9%/34.9%/14.5%</li> <li>PV - 4.6%/37.9%/10.6%</li> <li>NPV - 9.8%/25.2%/16.9%</li> </ul>

Method documentation
Process step
- Description
- The long-term statistical summary products are derived from the sentinel2 seasonal fractional cover product, also produced by the QLD DETSI earth observation team. The statistical products are derived from the full time series of imagery available for each season, defined by standard calendar seasons.
Process step
- Description
- Seasonal Statistics - 6 Band images: <br></br> band 1 – 5th percentile minimum - robust minimum value for that pixel over the length of the full time series (percentage) <br></br> band 2 – mean value for pixel over full time series (percentage) <br></br> band 3 – median value for pixel over full time series (percentage) <br></br> band 4 – 95th percentile maximum - robust maximum value for that pixel over the length of the full time series (percentage) <br></br> band 5 – Standard deviation - the temporal standard deviation of the full time-series <br></br> band 6 – Count - the number of observations statistics for that pixel are based on for that season only.<br></br>
