He also showed around the EcoDataCube platform that hosts the data cube and the land cover maps!

This presentation showcased the OpenClimate platform, the data schema and data aggregation work done, and its roadmap and opportunities of collaboration for the open source and open data community.

In this presentation, Quentin Groom wanted to give attendees a sense of biodiversity data, where it comes from, what they want to learn from it, and what the challenges are. He did this in the context of the B-Cubed project ( that aims to contribute to solving some of these challenges and made particular reference to citizen science for the collection of data and the advantages and challenges this presents.

Paolo Filippucci presented a methodology to derive river discharge information from near-infrared (NIR) satellite sensors. The approach has been applied to different river basins worldwide in the framework of the ESA projects RIDESAT, STREAMRIDE, HYDROCOASTAL and 4DMED-hydrology, by using NIR data sensed by MODIS and Sentinel-2 sensors.

In this presentation, Joan Maso showed that in order to make sense of sensor data, a data model that semantically tags the data is needed. Sensor Things API helps to map “data columns” to concepts (time, observed property, location, etc.), making the data machine-readable, and as a bonus, this structured API has rich query capabilities.

This presentation is an overview of the development of CEOS-ARD, its current status, and provided an outlook on the next steps in CEOS-ARD and the OGC SWG.

This webinar introduces sits, an open-source R package for land use and land cover classification of big Earth observation data using satellite image time series.
Forest degradation is hard to spot by satellites, and its effects in the rain forest remain underestimated. An important part of Amazon degradation is induced by fire; however, the successive use of fire over the same area has often been overlooked. In this presentation, Alber Sanchez introduces it's team's efforts to answer this question using the Brazilian near real-time deforestation detection system (DETER).
Satellite images can be used to derive time series of vegetation indices, such as normalized difference vegetation index (NDVI) or enhanced vegetation index (EVI), at global scale. Unfortunately, recording artifacts, clouds, and other atmospheric contaminants impacts a significant portion of the produced images, requiring the usage of ad-hoc techniques to reconstruct the time series in the affected regions. In literature, several methods have been proposed for this scope, to the best of our knowledge, none of them provide an open source framework that can be applied to the reconstruction of remote sensing dataset of size in the order of PetaBytes with good performance and reasonable computational time. Davide Consoli presents here a new method that he and his team implemented in OpenGeoHub to tackle those challenges. In addition to the reconstructed time series, the method outputs a quality assessment layer to quantify the expected effectiveness of the reconstruction.


This talk describes these processes of land cover change and discusses how they can be assessed using satellite remote sensing observations, thanks to some methodological tools involving space-for-time substitution that are being improved and developed within the OEMC project.
This talk presents how the EODC can be used to monitor environmental changes across countries and can enable more effective responses to problems of national and regional significance.
In this session a broad introduction to In-situ data and the definitions used was given. It provided an overview of authoritative and non-authoritative data sources, the importance of In-Situ data for training remote sensing deep learning models (showcasing WorldCover and C-GLOPS training data sets, etc.) and other citizen science data (e.g. iNATURALIST etc.). Methods for how in-situ data can be extracted from Mapillay and Streetview were also discussed.

This talk provided a brief overview of the Geo-Wiki application for the collection of land cover and land use reference data using crowdsourcing and the visual interpretation of very high-resolution satellite imagery. These reference data have been used to create training data sets and to validate land cover/land use products in a range of different applications including cropland extent, forest management and the drivers of deforestation, which will be presented in brief.

Recent advancements in technology and increased understanding of scientific issues at a large scale have facilitated a broader perspective in numerous scientific studies, thereby presenting novel challenges. Standardization and harmonization have emerged as pivotal concepts across various aspects of ecological research, encompassing instrumentation, methodologies, data processing, quality, metadata. This talk explores the evolution over the past three decades of in-situ measurements of greenhouse gas (GHG) fluxes worldwide, from initial campaigns to the establishment of the FLUXNET community, to investigate the current challenges and the possible advancements in this field.
This talk covers the key innovative aspects in Earth Observation data management introduced by the Copernicus Data Space Ecosystem and its commercial component, CREODIAS. These aspects include access to entire archives of Copernicus satellite data with immediate online availability, a range of data access and processing APIs, mechanisms for tracing data product integrity, as well as tools for collaborative data analysis and visualization, and support for custom data processing workflows.
