DEA Multi-Year Water Observation Frequency Statistics (Landsat, DEPRECATED)
Water Observations from Space Statistics 25m 2.1.5 (Landsat, Frequency)
Water Observations from Space (WOfS) Statistics is a set of statistical summaries of the WOfS product which combines WOfS observations into summary products that help the understanding of surface water across Australia. WOfS Statistics is calculated from the full depth time series (1986 – 2018). The water detected for each location is summed through time and then compared to the number of clear observations of that location. The result is a percentage value of the number of times water was observed at the location. The layers available are: the count of clear observations; the count of wet observations; the percentage of wet observations over time (water summary).
This layer contains the Water Summary: the percentage of clear observations which were detected as wet (ie. the ratio of wet to clear as a percentage). No clear observations of water causes an area to appear transparent, few clear observations of water correlate with red and yellow colours, deep blue and purple correspond to an area being wet through 90%-100% of clear observations.
As no confidence filtering is applied to this product, it is affected by noise where misclassifications have occurred in the WOfS water classifications, and hence can be difficult to interpret on its own. The confidence layer and filtered summary are contained in the Water Observations from Space Statistics Filtered Summary product, which provide a noise-reduced view of the water summary.
