Lake Water Extents derived from Sentinel-2 time series, ICube-SERTIT

SERTIT’s Rapid Mapping Service (RMS) has been ISO 9001 certified since 2011 for the production of crisis and emergency geoinformation under time constraints. This is a guarantee of quality and conformity of the products and services provided with respect to the specifications of its customers. Leveraging its 11 years of RMS certification, SERTIT decided in […]

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 […]

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 […]

Following the Hunga Tonga Hunga Haapai eruption, ICube-SERTIT was requested by the CNES to highlight the impact over the Tongan Islands within the framework of the International Charter Space & Major Disasters. The maps below use post-event Pleiades and pre-event WorldView imagery over Hunga Tunga, Nomuka, and Nuku Alofa islands. The Hunga Tonga Hunga Haapai […]

Our intern Vitória has worked this summer to improve our fire detection algorithm based on Sentinel-2 data exploitation. The accuracy assessment performed on 12 test sites all over the world (Europe, Africa, South America and Oceania) indicates a real step forward in the thematic quality of the burnt areas detected. Thanks to her new insights, […]

We are proud to announce the release of EOReader, a remote sensing open source python library allowing the user to open multiple satellite sensors, both optical and SAR (Sentinel 1, 2 and 3, Landsats 8 to 1, COSMO-SkyMed, RADARSAT-2 and TerraSAR-X). EOReader can be used to load satellite bands, clouds from files, DEM and optical […]

ICube-SERTIT’s catalogue of rapid mapping actions is now accessible through a read-only REST API. In order words you can view our rapid mapping assets through a machine friendly interface. For instance the complete catalogue of public rapid mapping actions is accessible through the following URI: https://sertit.unistra.fr/wp-json/rms/v1/actions Issuing a HTTP GET request on this address will […]

LWE derived from Sentinel-2 time series, ICube-SERTIT processing ExtractEO, an automatic water detection workflow developped by ICube-SERTIT, was applied to the Sentinel-2 time series covering Fitri Lake from January 2017 to February 2021, deriving a lake mask for each Sentinel-2 acquisition date. The ExtractEO pipeline downloaded 246 Sentinel-2 images from the CREODIAS platform and detected […]
