Copernicus Sentinel-1 helps map extent of floods

On ESA web-site a new article was published about flood detection in Argentina.

We used ESVI in different variations to show the extent and evolution of a flood event, which took place on Feb 14, 2020 in Santiago Estero Province.

In rainy seasons we often have no access to optical images. Sentinel-1 SAR data is the perfect alternative to create map products from time-series data.

Many thanks again for the editorial support to Mali Cecere.

Have a look at the web-site of ESA where you find the article:
