Seasonal Ground Cover Statistics - Landsat, JRSRP Algorithm Version 3.0, Queensland Coverage
<p>The Seasonal ground cover statistics products are long-term temporal statistic products derived from the seasonal ground cover product for each fraction across Queensland for the 30 year timeseries. There is one raster image for each season and each bare and green fraction for the full time series of imagery available. Statistics include:<br>
band 1 – 5th percentile minimum;<br>
band 2 – mean value for pixel over full time series for that season only (percentage + 100); <br>
band 3 – median value for pixel over full time series for that season only (percentage + 100); <br>
band 4 – 95th percentile maximum; <br>
band 5 – Standard deviation - the temporal standard deviation of the full time-series for that season only; <br>
band 6 – Count - the number of observations statistics for that pixel are based on for that season only.</p>
<p>Min/max (5th and 95th percentile) products are also made for each fraction using all seasonal ground cover images available during the long term data period (currently 1990-2020).</p>

- Purpose
- These products display the variation of the seasonal ground cover fractions over long term temporal periods (e.g. 1990-2020).<br> These products are based upon the JRSRP Fractional Cover 3.0 algorithm.

Data quality info

- Other
- The input imagery was processed to level L1T by the USGS. Geodetic accuracy of the product depends on the image quality and the accuracy, number, and distribution of the ground control points. The fractional cover model was compared to samples drawn from approximately 4000 field reference sites.
Report
Result
- Statement
- The USGS aims to provide image-to-image registration with an accuracy of 12m. Refer to the L8 Data Users Handbook for more detail. The fractional cover model predicts the vegetation cover fractions with MAE/wMAPE/RMSE of:<br> bare - 6.9%/34.9%/14.5%<br> PV - 4.6%/37.9%/10.6% <br> NPV - 9.8%/25.2%/16.9%.<br>

Process step
- Description
- <p>The long-term statistical summary products are derived from the seasonal ground cover product <a href="https://portal.tern.org.au/seasonal-ground-cover-australia-coverage/22022">https://portal.tern.org.au/seasonal-ground-cover-australia-coverage/22022</a>, also produced by the QLD DES remote sensing centre. The statistical products are derived from the full time series of imagery available for each season, defined by standard calendar seasons. For each pixel, the following statistics are calculated: 5th percentile, mean, median, 95th percentile, standard deviation and count.</p>
Process step
- Description
- <p>Seasonal Statistics - 6 Band images:<br> band 1 - 5th percentile minimum - robust minimum value for that pixel over the length of the full time series for that season only (percentage + 100) <br> band 2 - mean value for pixel over full time series for that season only (percentage + 100) <br> band 3 - median value for pixel over full time series for that season only (percentage + 100) <br> band 4 - 95th percentile maximum - robust maximum value for that pixel over the length of the full time series for that season only (percentage + 100) <br> band 5 - Standard deviation - the temporal standard deviation of the full time-series for that season only <br> band 6 - Count - the number of observations statistics for that pixel are based on for that season only. <br> The first 4 bands are recorded with a scaling factor of 100 for data management purposes (to ensure there are no negative values in the image).</p>
Process step
- Description
- <p>Min/Max Statistics - 2 Band images:<br> A two band image is produced for the Min/Max for full time series:<br> band 1 - 5th percentile minimum - robust minimum value for that pixel over the length of the full time series (percentage + 100)<br> band 2 - 95th percentile maximum - robust maximum value for that pixel over the length of the full time series (percentage + 100)</p>
