Water is one of the world’s most important resources as it’s critical for human consumption, agriculture, the persistence of flora and fauna species and other ecosystem services. Information about the spatial distribution and prevalence of water is necessary for a range of business, modelling, monitoring, risk assessment, and conservation activities. The water count product is based on water index and water masks for Queensland (Danaher & Collett 2006) and represents the proportion of observations with water present across the Landsat time series as a fraction of total number of possible observations for the period 1 Jan 1988 to 31 Dec 2022. The product has two bands where band 1 is the number of times water was present across the time series, and band 2 is the count of unobscured (i.e. non-null) input pixels, or number of total observations for that pixel. Cloud, cloud-shadow, steep slopes and topographic shadow can obscure the ability to count water presence. {"type": "Polygon", "coordinates": [[[138.0, -29.2], [154.0, -29.2], [154.0, -9.5], [138.0, -9.5], [138.0, -29.2]]]} 138.0 154.0 -29.2 -9.5 Water Count Time Series Data File documentDigital tif Landscape Data Visualiser documentDigital HTML water_count documentDigital Water Count Time Series WMS ro-crate-metadata.json documentDigital HTML Water_count documentDigital JPEG Unnamed resource documentDigital PNG
