Martijn is a PhD candidate at OpenGeohub Foundation, focusing on large-scale spatiotemporal land cover modeling. During the Open-Earth-Monitor Science Webinar Martijn presented OpenGeoHub’s efforts at creating a harmonized, multi-source spatiotemporal data cube for Europe, and how this data cube was used to produce consistent continental annual land use/ land cover maps. He also showed the EcoDataCube platform that hosts the data cube and the land cover maps! Following this presentation, he was asked a few questions by OEMC’s Working Package 6 OpenGeoHub’s communication experts.
