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 […]

Introduction to EOReader, a remote-sensing open source Python library developed by SERTIT to tackle rapid mapping challenges. Context 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. In rapid […]
Water and its management are crucial issues, especially in times of climate change and biodiversity loss. In this context, water surfaces such as lakes are particularly interesting areas. Earth observation data is playing an important role in assessing and monitoring this resource. The scientific community, with the development of dedicated satellite missions such as SWOT […]
