10 m spatial resolution flood masks associated with two Tropical Cyclone Events (TC Yasa in 2020 and TC Cody in 2022) have been generated. The flood masks were generated by applying a threshold to a ratio of pre- and post-event Sentinel-1 SAR data following a method presented by UN-SPIDER and an implementation from Gandhi (2021).
Flood masks have been generated for tropical cyclone events where there was sufficient cloud-free optical images to verify that the Sentinel-1 flood masks correspond to actual flooding.
The Google Earth Engine scripts used to generate the flood masks and visually verify flooding are included in this GitHub repository.
