The project aims at defining the scientific methods and the related prototype algorithms for addressing three main challenges with the multispectral and multiresolution Sentinel 2 images: 1) change detection; 2) analysis of image time series; and 3) updating of land-cover maps.
The possibility to operationally monitor the Earth’s land cover (changes) at high temporal resolution is nowadays given by EO multispectral dense time series available at global level, in particular Sentinel-2 and Landsat 8 data. Nonetheless, keeping thematic maps regularly updated is a complex and time consuming task. Large efforts have been devoted to date in …
Regional sea level trends present large spatial patterns caused by natural variability (changes in winds, air-sea flux etc.) along with anthropogenic influences in the atmosphere. These sea level trends can be partially masked by random oceanic processes. Global mean sea level rise is one of the most direct consequences of the on-going global warming. Based …
The aim of the CryoTop Evolution is to generate L2, L3 and L4 products over the Greenland and Antarctic ice sheets from swath processing of CryoSat SARIn mode data. The CryoTop datasets contain surface elevation generated from swath processing of CryoSat-2 measurement. The CryoTop datasets also contain gridded products generated from the swath derived elevation, …
This SEOM study is to develop, implement and validate algorithms for deriving several key snow parameters from Sentinel 3 optical satellite data, appropriate for addressing ESA’s Cryosphere challenge (Seasonal snow, lake/river ice and land ice, their effect on the climate system, water resources, energy and carbon cycles: the representation of terrestrial cryosphere in land surface, …
The main objective is the development, implementation and validation of methods and tools for generating maps of snowmelt area based on SAR data of the Sentinel-1 mission and the combination with snow products derived from optical sensors of Sentinel-2 and Sentinel-3 missions. The developed algorithm will be used to generate multi-sensor pan-European snow products. A …
Development and inter-comparison of algorithms for validating the radiometry of Sentinel-2 Level-1 products.According to the definition used by the Working Group on Calibration and Validation (WGCV) of the international Committee on Earth Observation Satellites (CEOS), validation is the process of assessing, by independent means, the quality of the data products derived from the system outputs. …
The European Space Agency is organising POLinSAR 2019, the 9th International Workshop on Science and Applications of SAR Polarimetry and Polarimetric Interferometry. The Workshop is open to: ESA Principal Investigators, scientists and students working in the field of SAR Polarimetry and Polarimetric Interferometry; Users of Copernicus data as well as national SAR missions Representatives from National, European …
This workshop will assess the opportunities for Atlantic region focussed EO research and development, downstream activities and ICT evolution, which may be the basis for future ESA investments to address some of the key information needs of this important area. These opportunities will be framed with respect to emerging Earth science, development of novel applications, …
The Mediterranean Sea region is surrounded by 22 countries, which together share a coastline of 46000 km. About 250 million people resides in coastal hydrological basins and a 50% population growth was reported in 20 years at the end of the 90’s. Fragility and vulnerability of the Mediterranean system is well known and since the …
