Introduction This study, carried out by Juliette Jourdan as part of an internship, was aimed at evaluating and refining FireML, a machine-learning algorithm developed by SERTIT for the rapid delineation of burned areas from mono-temporal Sentinel-2 imagery in operational emergency mapping contexts. The objective was to identify the main factors limiting performance and to assess […]
Introduction When a disaster occurs, SERTIT must deliver crisis information within hours. Delays in delineating affected areas, such as burn scars or flood extents, can affect decision-making by civil protection authorities. To accelerate this process, the potential of Meta AI’s Segment Anything Model (SAM) was investigated for rapid mapping applications. As part of an internship […]
Introduction The rapid and reliable identification of infrastructure damage is a major concern for security and territorial monitoring actors. In response, Earth observation provides unique capabilities for regular monitoring. Sarimpact was developed in this context as part of the SECURE-SAT project funded by the University of Strasbourg and the Carnot Institute. The tool aims to […]
Presentation of geoprocessing methods inspired by specialized data-visualization journalism in security applications. Introduction Recent conflicts are scrutinized by many observers, both in terms of information collection and its processing. Journalists are at the forefront of these methodological shifts. Field reports, crisis communication, articles and in-depth analyses, social media… The mass of open-source data is fertile […]
Increasingly frequent and destructive floods leave a lasting mark on territories and on people. They stand out as the natural hazard accounting for the highest number of activations within the emergency mapping program – Copernicus Emergency Management Service – Rapid Mapping (CEMS RM) (Maxant, J. et al., 2022). To meet the needs of risk and […]
Piton de la Fournaise began a new eruption on January 18, 2026 at 7:48 PM local time (3:48 PM UTC). The eruptive site is located on the northern flank of the terminal cone, inside the Enclos Fouqué. Four eruptive fissures opened successively between 7:45 PM and 8:54 PM. The ICube-SERTIT team produced a Sentinel-1 interferogram […]
The International Charter on Space and Major Disasters celebrates its 25th anniversary, a milestone that coincides with the CNES assuming the Charter’s presidency from October 2025 to April 2026. As a pioneer in rapid mapping, ICube-SERTIT has supported the CNES in this international cooperation since the Charter’s first activations. SERTIT produces value-added satellite imagery products […]
Nearly three months ago, SERTIT had the pleasure to participate in ESA’s Living Planet Symposium in Vienna, Austria, from the 23rd to the 27th of June 2025. As the slides are now available online, we are pleased to share with you a small overview of our presence at the Symposium. It has been an intense […]
