A partnership between the European Commission's Joint Research Centre and Google Earth Engine has yielded a new online interactive mapping tool that highlights changes in Earth's surface water over the past 32 years.
The Global Surface Water Explorer, which consists of 3 million Landsat images collected over the last 32 years, shows that impacts on surface water occurrence can come from a variety of factors.
The information contained in this tool will improve additional surface modeling, help to mitigate flooding, and improve global policies and water-management decision making. The Global Surface Water Explorer tool is available to everyone at no charge.
