Earth observation data can provide a wealth of information by virtue of its comprehensive geo-temporal coverage, the range of instruments and sensing platforms and the sophistication with which measurements can be derived from the Earth system. These can be applied to obtain insights into the interaction between human activity and the Earth system. Particularly important factors in recent times have been the recognition of the value of both public service (state-funded through space agencies) and commercial constellations, good access to key data sets from trusted sources and the desire to combine data sets for high level product or information services relevant to environmental sciences. Hitherto, the UK strategy has been to invest in data centres, hubs and platforms via Europe and both science assets such as the Centre for Environmental Data Analysis (CEDA) and UK software and data platform companies have been successful in obtaining funding in a European context. This project is a very important first step driven by the UK's new National Space Strategy (NSS) which identifies the opportunity of market growth in EO, the need for world-leading science and technology e.g., the fight against climate change, and the value of international partnerships.The sheer scale of EO datasets can presents barriers to its effective exploitation due to a significant growth in types of sensors, in data volumes, and in data products which are essential outputs from satellites for science to services. Furthermore, practitioners often wish to combine EO with sensor networks, model data and, in a new challenge, digital twins of the Earth.The EO DataHub seeks to meet these challenges, capitalise on UK strengths and take the opportunity to create a first UK infrastructure capable of serving public and commercial EO data, alongside other data sources, to a wide range of users from science to industry to government. The key attributes of this pre-operational service, which is intended to be free in this phase to UK users at the point of use, are the following:- A federated approach using UK-specific software infrastructure which is state-of-the-art, and demonstrably keeps the UK at the forefront of digital EO technologies, reducing data downloads and data volumes for storage- Platforms for specific sectors which are judged to enable the most benefit in this phase of the project; one will be climate.- Pilot projects and champion users which will support progression of the concept, specifications, evaluation and demonstration.Software wrappers to allow algorithms to run at data sources (selected sources)- Access to scientific, public and commercial data sets; the last by procurement and negotiation.- A central place for NERC community EO data sets, alongside its Environmental Data Service, specifically serving the outputs of the UKEO Climate Information Service (UKEO CIS) and model data from the Coupled Model Intercomparison Project, CMIP6.Through the provision of a shared software infrastructure and user services, the data hub will seek to address the issues around fragmentation of data access and services experienced by the user community. Data streams from the academic and commercial sectors will build on and provide continuity from previous UK investments, including high quality, Essential Climate Variable UK-produced datasets and UK-specific datasets; high-profile climate model simulations - CMIP and CORDEX; access to operational data streams and commercial data streams. By providing an innovation laboratory, the EO Data Hub expects to support academic, industry and government users leading to 1000+ users; five large-scale, impactful activities with business or national stakeholders; support to at least 10 SMEs per year and 10 government users.

地球观测数据凭借其全面的地时覆盖范围、仪器和传感平台的范围以及从地球系统获得测量结果的复杂性，可以提供丰富的信息。这些可以用来深入了解人类活动与地球系统之间的相互作用。近年来特别重要的因素是对公共服务（国家通过航天机构资助）和商业星座的价值的认识，可以从可信来源轻松访问关键数据集，以及将数据集组合起来以获得高水平产品或服务的愿望。与环境科学相关的信息服务。迄今为止，英国的战略一直是通过欧洲投资数据中心、枢纽和平台，环境数据分析中心 (CEDA) 等科学资产以及英国软件和数据平台公司都已成功在欧洲背景下获得资金。该项目是英国新的国家太空战略（NSS）推动的非常重要的第一步，该战略确定了环氧乙烷市场增长的机会、对世界领先科学技术的需求（例如应对气候变化）以及由于传感器类型、数据量和数据产品的显着增长，EO 数据集的庞大规模可能对其有效利用构成障碍，而数据产品是卫星科学到服务的重要输出。此外，从业者通常希望将 EO 与传感器网络、模型数据以及地球的数字孪生体（在新的挑战中）结合起来。EO 数据中心力求应对这些挑战，利用英国的优势，并借此机会创建第一个英国基础设施能够为从科学到工业到政府的广泛用户提供公共和商业EO数据以及其他数据源。这项预运营服务的关键属性如下：- 使用英国特定软件基础设施的联合方法，该基础设施是最先进的-艺术，并且明显使英国处于数字EO技术的前沿，减少了数据下载和存储数据量——特定部门的平台被认为能够在项目的这一阶段实现最大利益；其中之一是气候。- 试点项目和冠军用户将支持概念、规范、评估和演示的进展。允许算法在数据源（选定来源）上运行的软件包装器- 访问科学、公共和商业数据集；最后通过采购和谈判。- NERC 社区 EO 数据集及其环境数据服务的中心位置，专门服务于 UKEO 气候信息服务 (UKEO CIS) 的输出和耦合模型比对项目 CMIP6 的模型数据。通过提供共享软件基础设施和用户服务，数据中心将寻求解决用户社区所经历的数据访问和服务碎片化的问题。来自学术和商业部门的数据流将建立在英国先前投资的基础上并提供连续性，包括英国生产的高质量基本气候变量数据集和英国特定数据集；备受瞩目的气候模型模拟 - CMIP 和 CORDEX；访问运营数据流和商业数据流。通过提供创新实验室，EO数据中心预计将支持学术、工业和政府用户，从而导致超过1000名用户；与企业或国家利益相关者开展五项大规模、有影响力的活动；每年支持至少 10 家中小企业和 10 家政府用户。
