GDE Surface Victoria

Groundwater Dependent Ecosystems (GDEand#39;s) information derived from the Bureau of Meterology National Atlas. GDEand#39;s (surface) are ecosystems which rely on the surface expression of groundwaterandnbsp;including all groundwater-fed surface water bodies such as wetlands, rivers, lakes and springs.andnbsp;\r\n\r\nFrom The BOM Metadata link:\r\n\r\nThe aquatic GDE layer is comprised of data from the 2012 GDE Atlas layerandmdash;GDE reliant on the surface expression of groundwaterandmdash;combined with new State and regional datasets ranging from 2012 to 2016. The 2012 GDE layer was derived from a national assessment involving remote sensing using Landsat and MODIS, and GIS rules-based analysis. The States/regions that have been updated with new surface GDE data include Queensland (wetlands, waterways and springs), Victoria (wetlands, waterways and some springs), the South Australian portion of Lake Eyre Basin (wetlands and springs), New South Wales (springs) and Northern Territory (springs).\r\n\r\nThe data is categorised by and#39;potential of ecosystem to be a GDEand#39;, which is classified as either known or potential (high, moderate or low) GDEs. This classification also highlights the different data sources, i.e. from the national assessment or from other studies.
