Earth observation missions nowadays produce enormous amounts of data about the Earth, its resources and human operations. EO data products are fundamental to society, as shown by EC Copernicus, and are one of the cornerstones of what ESA terms Space 4.0, which is expected to transform the lives of citizens, policymakers and businesses in the near future. Current and emerging trends in the EO market, driven by the sharp growth in applications based on EO products, show greater demands in the amount, type and quality of the EO products available to End Users. Data latency is also a key metric, with End Users requiring products in a very short time period, with low latency (NRT) or very low latency. EO-ALERT addresses the need for increased data chain throughput within the COMPET-3 call. It proposes a fundamentally new approach for the provision of low latency EO data products, which exploits the flight segment processing capabilities and breaks with the traditional sequential EO data chain focused on the raw

The NextGEOSS project will implement a federated data hub for access and exploitation of Earth Observation data, including user-friendly tools for data mining, discovery, access and exploitation. This data hub will be supported by a strong commitment to the engagement of Earth Observation and related communities, with the view of supporting the creation of innovative and business oriented applications. The main general objectives for NextGEOSS are to 1) Deliver the next generation data hub and Earth Observation exploitation for innovation and business; 2) Engage communities, promoting innovative GEOSS powered applications from Europe; and 3) Advocate GEOSS as a sustainable European approach for Earth Observation data distribution and exploitation. NextGEOSS engages main providers of Earth Observation data, including Copernicus Collaborative Ground Segments and Core Services. While continuing to support the GEO-DAB and OpenSearch as the middleware components in charge of interconnecting the heterogeneous and d
