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.

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.

Floods are amongst the most frequent and damaging disasters globally. To map urban floods accurately, SERTIT’s team offers a solution in the form of a specific tool: FLORIA.

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 […]

Introduction to EOReader, a remote-sensing open source Python library developed by SERTIT to tackle rapid mapping challenges. As one of the Copernicus Emergency Management Service Rapid Mapping and Risk and Recovery Mapping operators, SERTIT needs to deliver geoinformation (such as flood or fire delineation, landslides mapping, etc.) based on multiple EO constellations. Context In rapid […]

In the frame of the study of the dynamics of water bodies in the Grand-Est region (France), the water surface time series for the gravel pit in Nordhouse (next to the Plan d’Eau de Plobsheim) has been produced. This was made possible through the use of the ExtractEO processing chain. The accuracy of the analysis […]
