Facilitated by support from CNES, the French national space agency, the French tech-driven insurer providing parametric insurance against climate and emerging risks, Descartes Underwriting and the public research lab specialized in remote-sensing and image processing, SERTIT, are advancing the application of data and science through its joint collaboration. Following a highly competitive application process, Descartes and SERTIT have […]
Important seismic and volcanic activity struck the area around the city of Grindavík at the end of the year 2023. A volcanic cycle began in early 2020 around this locality, located on the Mid-Atlantic Ridge, with magma movements below the surface and the formation of a graben. In particular, significant tectonic activity and ground movements […]

Wildfires have grown increasingly prevalent, causing significant socio-economic and environmental damage. As a result, the emphasis on efficient detection and delineation of fire events has driven the development of novel methodologies and techniques over the years. Reflecting this trend, SERTIT’s intern, Oscar Narvaez worked on an exploratory project during summer 2023, aiming to assess the potential […]
FLORIA, a tool designed to identify urban flooding based on radar imagery Floods are amongst the most frequent and damaging disasters globally. When a flood occurs in urban areas, risks are even higher because of the density of residents, buildings and infrastructure. Being less sensitive to atmospheric conditions than optical images, radar imagery has the […]
Context The Kakhovka hydroelectric dam in northern Ukraine has been the target of attacks, causing it to burst on 6 June 2023. Unprecedented flooding hit towns and villages as far downstream as the mouth of the Dnieper, forcing thousands of people to quickly evacuate. As well as producing electricity and supplying drinking water, the dam […]
Lake Water Extents derived from Sentinel-2 time series, ICube-SERTIT As part of the CCI Lakes project, ExtractEO, an automatic water detection workflow developed by ICube-SERTIT, was applied to the full Sentinel-2 time series covering Lake Argyle, Australia, from January 2016 to August 2022, deriving a lake mask for each Sentinel-2 acquisition date at 10m ground […]
