Lake George water levels for the period 1987–2019, estimated using Landsat and Sentinel satellite imagery. Data were obtained by performing a query of the Open Data Cube (ODC; Open Data Cube, 2020) Landsat and Sentinel archive using scripts from the Digital Earth Australia Notebooks repository (Geoscience Australia, 2020). These images were subsequently processed to estimate lake depths based on the Lake George area/depth relationship presented in Dataset I. Refer to the Australian Journal of Earth Sciences article associated with these datasets for more information on the imagery processing methods.Geoscience Australia (2020, January).
