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.

地球观测数据由于其全面的地球时间覆盖面、仪器和传感平台的范围以及从地球系统得出测量结果的复杂性，可以提供丰富的信息。这些可用于深入了解人类活动与地球系统之间的相互作用。最近特别重要的因素是，认识到公共服务（国家通过空间机构提供资金）和商业星群的价值，能够很好地从可靠来源获得关键数据集，以及希望将联合收割机数据集结合起来，提供与环境科学有关的高级产品或信息服务。英国的战略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成功地在欧洲获得了资金。该项目是由英国新的国家空间战略（NSS）推动的非常重要的第一步，该战略确定了EO市场增长的机会，对世界领先的科学和技术的需求，例如，由于传感器类型、数据量和数据产品的显著增长，地球观测数据集的规模之大可能会阻碍其有效利用，而数据产品是卫星从科学到服务的基本产出。此外，从业者往往希望将联合收割机EO与传感器网络，模型数据，并在一个新的挑战，地球的数字双胞胎相结合。EO DataHub旨在应对这些挑战，利用英国的优势，并借此机会创建第一个英国基础设施，能够为公共和商业EO数据，以及其他数据源，从科学到工业到政府的广泛用户。这项预运营服务的主要属性，旨在在此阶段免费提供给英国用户使用，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，并证明英国处于数字EO技术的最前沿，减少数据下载和存储数据量-用于特定部门的平台，被认为能够在项目的此阶段获得最大利益;其中一个将是气候。试点项目和冠军用户将支持概念，规范，评估和演示的进展。软件包装，允许算法在数据源（选定的源）上运行-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数据集的中心位置，以及其环境数据服务，专门服务于UKEO气候信息服务（UKEO CIS）的输出和耦合模型相互比较项目CMIP 6的模型数据。通过提供共享的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问题。来自学术和商业部门的数据流将建立在英国以前投资的基础上，并提供连续性，包括高质量的基本气候变量英国生产的数据集和英国特定的数据集;高知名度的气候模型模拟- CMIP和CORDEX;获得业务数据流和商业数据流。通过提供一个创新实验室，EO数据中心预计将支持学术，工业和政府用户，导致1000多个用户;与企业或国家利益相关者一起举办五次大规模，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。
