InSAR (Interferometric Synthetic Aperture Radar) is a satellite-based remote sensing technology using radar waves to measure and monitor ground movement, which can provide valuable insights into the stability and safety of infrastructure. This is also particularly useful for detecting subtle changes in the ground, such as subsidence or other deformations and displacements, which can indicate …
In the framework of the EO AFRICA initiative, from January 29 – February 23, 2024 an online course is being organised by the EO AFRICA R&D Facility. The course will review a variety of different publicly and freely available data sets and tools for surface water detection and modelling using a full 2D version of …
Understanding the processes driving ice-ocean interactions and their timescale is pivotal in getting a full picture of the Antarctic sensitivity to future climate variability. A recently published study measured 2018-2019 increased speed and discharge of ice and calving front retreat for the Cadman Glacier, and highlighted correlation to a positive temperature anomaly in the upper …
The F2F course of the EO AFRICA R&D Facility will take place in Cairo, Egypt in close collaboration with the National Authority for Remote Sensing & Space Sciences (NARSS). In this course, participants will get an introduction to cloud-based techniques for assessing vegetation dynamics with Earth Observation data. The training includes face-to-face lecturing and reading …
Alexis is currently an ESA Living Planet Fellow at University College Dublin (UCD, Dublin, Ireland). Since 2020 he has worked at the Science Foundation Ireland (SFI) Centre in Applied Geosciences (iCRAG) at University College Dublin (Ireland) to study ecohydrological conditions of Irish and British peatlands by using InSAR and SAR observations. Previously he completed a …
New research, utilizing data from ESA’s Copernicus Sentinel-1 and CryoSat satellite missions, offers a stark view of the state of Antarctica’s ice shelves. Over the last 25 years, 40% of these vital floating extensions of the continent’s ice sheet have significantly diminished in volume, releasing approximately 67 trillion tonnes of meltwater into the ocean. This …
To address the need for higher spatial resolution datasets to monitor Land Degradation Neutrality (LDN). The SEN4LDN consortium aims to develop, demonstrate and validate robust and automated EO methods to map land cover changes and land productivity dynamics that exploit the high frequency and spatial resolution of Sentinel-1 and 2. Land degradation affects the livelihoods of millions of …
The “Raised Peatland Ecohydrology Evaluation through Sentinel-1 InSAR data and Machine Learning” (RaiPEAT_InSAR) project will investigate linkages between ecohydrological parameters of raised peatlands and InSAR estimates to classify of ecohydrological dynamics of peatlands. The main objectives are as follows: Ground validation of InSAR-derived surface motions of temperate raised peatlands by using co-located soil moisture, water …
Crop yield forecasting is a vital tool to support stakeholders and decision-makers in preparing for potential yield deficiencies. Most crop yield forecasts so far have been implemented on a regional to national scale. Field-scale forecasts can add vital information for farmers and insurers but still have much potential to improve. Especially the increasing availability of …
The WISE (Wide-Area Sentinel-1 Deformation Classification for Advanced Data Exploitation) project focuses on developing advanced tools to exploit the large amount of satellite-borne Synthetic Aperture Radar (SAR) data. The main data source will be the Sentinel-1 SAR data: this Copernicus mission provides, with its fast revisit time, high-resolution and multi-polarization, an unprecedented amount of data, …
