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), …
New research published in Geophysical Research Letters investigates in-situ ionospheric plasma measurements from the European Space Agency’s Swarm satellites coincident with ground-based optical measurements of the phenomenon known as “Steve”. The authors show that Steve is consistently associated with narrow ionospheric flow channels called subauroral ion drifts (SAID). These observations are unusually intense with faster …
The European Space Agency’s Earth Observation for Sustainable Development (EO4SD) Climate Resilience Cluster is holding a webinar to demonstrate the potential for Earth Observation to contribute to climate resilient development objectives. The webinar “How can EO data support climate resilient development?” will take place twice on the 11th June 2019: 10-11 am CEST / 3-4 …
Applying a novel analytical theory, scientists have a fast new way of retrieving snow grain size – and albedo – from Sentinel-3 data. Read more about the importance of snow grain size and the results obtained in the Pre-Operational Sentinel-3 snow and ice products (SICE) project in ESA EO portal featured story.
The “Euro Data Cube Facility” service contract was Kicked-off on April 23 for a project duration of 3 years, focusing not just on development of innovative product, but mostly on an operational service to be used by millions of people around the world. An initial portfolio of services will be available after 6 months and …
