"description": "Digital Earth Australia Waterbodies v3.0 provides up to date information about the extent and location of surface water, providing all Australians with a common understanding of this valuable and increasingly scarce resource. It supports users to understand and manage water across Australia. For example, users can gain insights into the severity and spatial distribution of drought or monitor critical lakes and dams, including hard-to-reach waterbodies in remote areas and on large properties. </br></br>The product indicates changes in the wet surface area of waterbodies. This can be used to identify when waterbodies are increasing or decreasing in wet surface area.</br></br>DEA Knowledge Hub product details: https://docs.dea.ga.gov.au/data/product/dea-waterbodies-landsat/?tab=overview.</br></br>Scientific paper: <a href='https://doi.org/10.3390/rs13081437'>Krause et al. 2021</a></small>.</br></br>DEA Website pages: https://www.dea.ga.gov.au/products/dea-waterbodies",

"content": "This product shows the wet surface area of waterbodies as estimated from satellites. It does not show depth, volume, purpose of the waterbody, nor the source of the water. Larger waterbodies are easier to detect and smaller or narrower waterbodies are harder to detect. Area estimates should be compared to additional data for verification.</br></br> Many of the inaccuracies and limitations of the waterbody analysis are inherited from DEA Water Observations (WO), with this product a reanalysis and mapping product built off the WO datasets. WO has a number of known limitations, and these manifest as misclassified waterbodies within this analysis. WO uses the spectral signature of water to classify wet pixels, and is known to be suboptimal in locations where water and vegetation are mixed. This includes locations such as rivers with vegetated riparian zones and vegetated wetlands.</br></br> Due to the way WO calculates the percentage of the water body observed and the way that satellite passes observe the water body, some of the larger salt lakes in Australia have very few records currently available. If less than 90% of the total waterbody is observed on any one day, due to cloud cover or missing data, than that observation is marked as a missing value. For larger bodies, which may cross multiple swath boundaries or suffer from misclassifications (salt lakes can be misclassified as cloud due to their brightness) this can be problematic.</br></br> For a full discussion of the limitations and accuracy of WO, see <a href='https://doi.org/10.1016/j.rse.2015.11.003'>Mueller et al., 2016</a></small>.</br></br>The update from version 2 to version 3.0 of the DEA Waterbodies product and service was created through a collaboration between Geoscience Australia, the National Aerial Firefighting Centre, Natural Hazards Research Australia, and FrontierSI to make the product more useful in hazard applications.</br></br>Geoscience Australia, the National Aerial Firefighting Centre, Natural Hazards Research Australia, and FrontierSI advise that the information published by this service comprises general statements based on scientific research.
