Flood Extent Detection

Overview

Flood extent is difficult to acquire as a true in situ reference because it is hazardous to operate in a flood zone, and physical access to the flood via roads, etc. are also equally hazardous and limited. Being able to detect flood extent provides automated ways to assist disaster response during flood events.

This competition seeks to develop approaches to delineate open water flood areas, helping to identify flood extent, an impactful disaster that occurs frequently throughout the world. The competition will involve a supervised learning task - participants will develop algorithms to identify flood pixels after training their algorithm against a training set of synthetic aperture radar (SAR) images.

Sample images and ground truth used for competition are shown in Fig. 1.
