Flood Mapping with Sentinel-1

In this webinar, you will learn the basics of image processing for flood mapping: we will show you how to access the RUS service and how to download, process, analyse and visualise the free data acquired by the Copernicus satellites constellation. We will employ the ESA SNAP Sentinel-1 Toolbox to demonstrate the flood mapping methodology on the disastrous event that occurred in January 2015 in Malawi.


Background

Amongst the different natural hazards, floods accounts for almost half of the weather-related disasters recorded during the last 20 years. Earth observation satellites can be used for flood mapping and assessment (e.g. early warning systems or post-disaster mapping).

The adverse weather conditions during flooding events make Synthetic Aperture Radar (SAR) a suitable approach due to its independence on weather and solar illumination. Since the launch of Sentinel-1, a European C-band SAR satellite, routine collections of large amount of data with short revisit times are made freely available, enhancing the capabilities of flood response activities.
