SUMMARY:Webinar: Hydrography90m\, pushing the boundaries of computational hydrology
DESCRIPTION:An open webinar on hydrology by the guest speaker Giuseppe Amatulli from Yale University.\n\n\nJoin this free webinar & contribute to the open-source community!\n\nREGISTER & LIVESTREAM HERE! \nHydrography90m: pushing the boundaries of computational hydrology \nStreams and rivers drive several processes in hydrology\, geomorphology\, geography and ecology. A global starized hydrographic network that accurately delineates streams and rivers\, along with their topographic and topological properties\, is needed for worldwide environmental applications. Using the MERIT Hydro Digital Elevation Model at 90m and by employing a suite of GRASS GIS hydrological modules\, we calculated the range-wide upstream flow accumulation and flow direction to delineate a total of 1.6 million drainage basins and extracted globally a total of 726 million unique stream segments with their corresponding sub-catchments. Besides\, we computed stream topographic variables comprising stream slope\, gradient\, length\, and curvature attributes as well as stream topological variables to allow for network routing and various stream order classifications. The validation shows that the newly developed Hydrography90m has the highest spatial precision and contains more headwater stream channels compared to three other global hydrographic datasets. \nMore information at https://doi.org/10.5194/essd-14-4525-2022 & https://hydrography.org/ \nREGISTER & LIVESTREAM HERE! \n\n\n\n\nAbout Giuseppe Amatulli\nDr Amatulli is a passionate forester and spatial modeller by training (M.Sc. & PhD in GeoScience and Forestry) and a computer scientist by trade. His research activity is mainly dedicated to spatial modelling\, GIS and remote sensing with special emphasis on tspecies distribution model\, areal distribution and potential shift under climate change conditions\, wildland fire occurrence and pattern recognition\, and wildfire risk assessment based on human and bio-physical parameters. \nUltimately\, he is dealing with geomorphology and hydrography analysis to derive high-accuracy flow estimation. He is daily dealing with high-resolution data in the context of complex and modern modelling techniques using stand-alone implementation processes under Linux environment. He uses open-source programming language and software (GRASS\, R\, PYTHON\, GNUPLOT\, AWK\, BASH\, QGIS\, OPENEV\, CDO) to accomplish large data processing in cluster processing keeping always in mind the ecological and geophysical aspects of the research study. He supports the use of open-source for geocomputation and machine learning modelling giving dedicated courses using (and maintaining) the www.spatial-ecology.net web page. \nREGISTER & LIVESTREAM HERE!

SUMMARY:Seminar Digital Twins for Earth Sciences: How to prepare your infrastructure?
DESCRIPTION:Destination Earth\nDestination Earth (DestinE) aims to develop – on a global scale – a highly accurate digital model of the Earth to monitor and predict the interaction between natural phenomena and human activities. DestinE will unlock the potential of digital modeling of the Earth system at a level that represents a real breakthrough in terms of accuracy\, detail\, access-to-information\, speed and interactivity. \nThrough the unprecedented observation and simulation capabilities of DestinE\, empowered by  a new digital infrastructure (incl. EuroHPC Exascale systems) and AI capacity\, we will be better prepared to respond to major natural disasters\, adapt to climate change and predict the socioeconomic impact. DestinE supports the European Commission’s Green Deal action and Digital Strategy. \nChallenges for researchers\nThe amount of data available for Earth Sciences research is ever-growing. DestinE\, on the one hand\, will incorporate cutting-edge models and real-time measurements but\, on the other hand\, also generate huge amounts of new data. How can researchers ensure that they are ready to process and analyze this data for innovative research? Which infrastructures are already available and what is lacking? \nThis seminar brings together interested parties to discuss these questions and build the collaborations needed to prepare the Dutch research community for DestinE. \nFor whom\nResearchers\, Program managers\, IT support\, Data scientists \nOrganization\nThis seminar is organized by SURF in cooperation with the Netherlands Space Office (NSO). \nProgram\n\n\n\nTime\nSubject\n\n\n\n\n10:30 – 11:00\nWalk in\n\n\n11:00 – 11:10\nWelcome at SURF\n\n\n11:10 – 11:45\nKeynote:\nWilco Hazeleger (UU)\n\n\n11:45 – 12:10\nRaymond Sluiter (NSO)\nDestination Earth & Earth Observation Infrastructures\n\n\n12:10 – 12:35\nFemke Vossepoel (TUD)\nDigital Twins for safe and sustainable Delta development in a changing Climate\n\n\n12:35 – 13:35\nLunch\n\n\n13:35 – 14:00\nTBD\n\n\n14:00 – 14:10\nHaili Hu\, Raymond Oonk (SURF)\nWorking together with SURF for Earth Sciences\n\n\n14:10 – 15:10\nBreak out session / Futuring\n\n\n15:10 – 15:30\nBreak\n\n\n15:30 – 15:55\nTomislav Hengl (OpenGeoHub)\nDecentralized computing infrastructures and open source cloud-solutions for Digital Earth Twin systems (or how to scale-up a proven idea within a modest computing budget)\n\n\n15:55 – 16:30\nKeynote:\nThomas Geenen (ECMWF)\n\n\n16:30 – 17:30\nClosing and drinks
