During the last few years, the Nouvelle-Aquitaine coast has been repeatedly hit by severe storms causing coastline retreat of several meters (from 10 to 40 meters in 2013-2014, from 5 to 13 meters in 2018). Modelled sea-level rise impact on the same coastline is projected to cause (see the Néo Terra 2019 and the AcclimaTerra …
A strong earthquake of Mw 7.1 struck southern California, United States on July 6, 2019 preceded by another earthquake of Mw 6.4 on July 4. This was the strongest earthquake in California since the 1999 Mw 7.1 Hector Mine earthquake. The earthquake sequence took place on a remote and sparsely inhabited area of California, limiting …
7 years of CryoSat-2, jointly with other satellite altimetry data allowed scientists from DTU Space to develop an altimetric gravity model and exploit it to derive the first ever Arctic bathymetry map predicted from marine gravity. This has been combined with the existing IBCAO bathymetry map (derived from sparse ship soundings) to create a new …
Version 7.0 of the popular ESA SNAP toolbox (over 380k downloads) has been published. This version includes bug fixes, improvements and several new features as: New readers: AATSR L1 data in SAFE format, S-1 on AWS, RCM products, PAZ, ICEYE, RISAT-1, ALOS-2 in GeoTiff, Kompsat-5 in GeoTiff, MUSCATE, Landsat L2, Landsat ESA products, Pleiades, WorldView1-3, …
Interferometric (InSAR) short-time-series of Sentinel-1 SAR data acquired over central Europe were exploited in a new approach for the generation of large-scale thematic maps. Temporal features, extracted from the evolution of the interferometric coherence, together with backscatter, were used as input for a machine learning-based classifier. Three land cover classes were extracted: artificial surfaces, forests, …
Release in collaboration with OGC In July 2019 the Open Geospatial Consortium (OGC) announced the formation of the Blockchain and Distributed Ledger Technologies Domain Working Group (DWG). Participants in this new OGC DWG will focus on understanding the importance of, and requirements for, geospatial standardization within these revolutionary, disruptive technologies, reported OGC on its website. …
How can we measure air quality? How can we observe remote places with no safety risk? How do we monitor earthquakes and derive tsunami alerts? How can we join forces and give help during an emergency via a mapathon? These are only a few of the questions raised and discussed during the School Labs that …
A series of violent and harmful explosions occurred on 3 July afternoon at Stromboli volcano, causing one dead. Glowing hot bombs and lapilli were ejected from all over the summit area and produced an eruption column that rose approx. 3-5 km. A series of fires were caused by the hot debris falling back in the …
The animation above gives a visual impression of Mediterranean temperature dynamics during the last 9 years by displaying daily Medspiration L4 products of 2 km resolution SSTfnd from 30 August 2010 to 25 May 2019. Medspiration is an ESA- funded project, started in 2004, aimed at producing a robust and reliable set of Sea Surface …
Decision-makers, planners and scientists can easily find in the Urban Thematic Exploitation Platform (U-TEP) resources, including multi-source data and visualisation/analytics tools, that help them creating and maintaining sustainable urban environments in major cities but also in smaller, rural areas. One of the recent add-ons to the rich database is the World Settlement Footprint 2015 (WSF-2015), …
