MMFlood: A Multimodal Dataset for Flood Delineation from Satellite Imagery

MMFlood is remote sensing dataset derived from Sentinel-1 (VV-VH), MapZen (DEM) and OpenStreetMap (Hydrography). It provides a complete and well-rounded set of data specifically designed for flood events, focusing on three main features: worldwide distribution, manually validated annotations and multiple modalities.

• 1748 pairs of SAR images and pixel-level annotations exclusively based around flooded areas and taking into account 95 flood events in 42 different countries around the world, in a time span ranging from 2014 to 2021.
• Image size <2000x2000, image resolution of 20m .
• Manually verified flood events across the world with raw SAR acquisitions derived from Sentinel-1.
• Includion of Digital Elevation Model (DEM) images.
