Maximum two-monthly surface water extent for MDB from MIM and WOFS

The multi-index method (MIM) (refer to Ticehurst, Teng and Sengupta 2022 in the Related Links for a description of the method) was developed for mapping surface water across the Murray-Darling Basin (MDB) based on Landsat surface reflectance data available in Digital Earth Australia. More than thirty years of two-monthly images of surface water extent across the whole MDB have been produced using this method, along with Water Observations from Space (WOfS) to fill in any gaps associated with cloud cover due to the different cloud masks used. The data were produced as part of the Murray-Darling Basin Ecosystem Function (MDB-EF) and Murray-Darling Water and Environment Research Program (MD-WERP) projects. Note that a new improved version has been developed and is expected to be released late 2022.
