The Aquatic GDE layer depicts aquatic ecosystems which are dependent on the surface expression of groundwater, including all groundwater-fed surface water such as rivers, lakes, wetlands and springs. It shows the ecosystems that rely on groundwater that has been discharged to the surface. |

<DIV STYLE="text-align:Left;font-size:12pt"><P STYLE="margin:0 0 0 0;"><SPAN STYLE="font-size:16pt">The Aquatic GDE layer is comprised of data from the 2012 GDE Atlas layer, GDE reliant on the surface expression of groundwater, combined with new state and regional datasets ranging from 2012 to 2019. 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 which have been updated with new aquatic 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) and Northern Territory (springs).</SPAN></P><P STYLE="font-size:16ptmargin:0 0 0 0;"><SPAN><SPAN>The data is categorised by 'potential of ecosystem to be a GDE', 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. </SPAN></SPAN></P><P><SPAN /></P><P><SPAN /></P><P><SPAN /></P></DIV> |
