Seasonal Ground Cover Summary Statistics - Landsat, JRSRP Algorithm Version 3.0, Queensland Coverage
<p data-renderer-start-pos="234">The Seasonal Ground Cover Summary Statistics datasets provide long-term statistical summaries derived from the seasonal ground cover v3 data, calculated separately for each fraction. Two distinct product types are available, differentiated by their seasonal aggregation and statistical content.</p>
<ol start="1" data-indent-level="1">
<li>
<p data-renderer-start-pos="533">Seasonal Statistics per Fraction (Product Code: dpi)<br />For each season and ground cover fraction, a separate raster image is generated for the full time series of available imagery. Each image includes the following statistical layers: include:<br />band 1 – 5th percentile minimum;<br />band 2 – mean value for pixel over full time series;<br />band 3 – median value for pixel over full time series;<br />band 4 – 95th percentile maximum;<br />band 5 – Standard deviation - the temporal standard deviation of the full time-series;<br />band 6 – Count - the number of observations statistics for that pixel are based on.</p>
</li>
<li>
<p data-renderer-start-pos="1126">All-Seasons Percentile Summary (Product Code: dph)<br />This product summarises the 5th and 95th percentiles across all seasons for each ground cover fraction. It is delivered as a 2-band image, capturing the overall long-term minimum and maximum percentiles across the full time series (currently 1990-2020).</p>
</li>
</ol>
<p data-renderer-start-pos="1435">Version 4 update: Dataset filenames have been revised to now include fraction and season tags, replacing multiple stage codes. Related products are grouped under a single code for improved clarity and usability. Additionally, band values are now expressed as percentages (0–100) to match the parent seasonal ground cover dataset, rather than using the previous percent + 100 scaling.</p>

- 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:<ul style="list-style-type: disc;"> <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>

Process step
- Description
- <p>The long-term statistical summary products are derived from the seasonal ground cover product https://portal.tern.org.au/seasonal-ground-cover-australia-coverage/22022, also produced by the QLD DETSI remote sensing sciences team. 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) <br />band 2 - mean value for pixel over full time series for that season only (percentage) <br />band 3 - median value for pixel over full time series for that season only (percentage)<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)<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 no data value for all bands is 255.</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)<br />band 2 - 95th percentile maximum - robust maximum value for that pixel over the length of the full time series (percentage)</p>
