Derived data product DEA Water Observations
Witness the history of surface water
Digital Earth Australia (DEA) Water Observations uses an algorithm to classify each pixel from Landsat satellite imagery as ‘wet’, ‘dry’ or ‘invalid’. Combining the classified pixels into summaries, covering a year, season, or all of time (since 1987) gives the information on where water is usually, and where it is rarely.
The DEA Water Observations methodology has now been used in Switzerland, Columbia, and across all of Africa
A detailed understanding of water availability allows us to better understand wetlands, water connectivity and surface-groundwater relationships
Why monitor surface water?
Imagery for impact Protecting a precious resource in the Murray-Darling Basin
Digital Earth Australia datasets have helped raise New South Wales’ capacity for water governance by 500 per cent
Water data and Australian floods
Water observations from space contribute to a greater understanding of flooding, writes Director of DEA Product Development, Norman Mueller
