EO Data Hub

地球观测数据因其全面的地理时间覆盖范围、仪器和传感平台的范围以及可从地球系统获得测量的复杂程度而可提供丰富的信息。这些可以用来洞察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(由国家通过空间机构资助)和商业星座的价值，很好地获得来自可信来源的关键数据集，以及希望合并与环境科学有关的高级别产品或信息服务的数据集。到目前为止，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)和英国软件和数据平台公司等科学资产都成功地在欧洲获得了资金。这个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，该战略确定了地球观测市场增长的机会，对世界领先的科学和技术的需求，例如应对气候变化，以及国际合作的价值。由于传感器类型、数据量和数据产品的显著增长，地球观测数据集的巨大规模可能会对其有效利用构成障碍，这些数据产品是卫星对科学和服务的基本产出。此外，实践者经常希望将EO与传感器网络、模型数据以及在新的挑战中与地球的数字孪生兄弟结合起来。EO数据中心寻求迎接这些挑战，利用英国的优势并借此机会创建第一个英国基础设施，能够与其他数据源一起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。这项运营前服务的主要特点如下：--使用英国特有的软件基础设施的联合方法，这是最先进的，并明显地使英国处于数字EO技术的前沿，减少了数据下载和用于存储的数据量--被认为在该项目的这一阶段实现最大利益的特定部门的存储平台；一个是气候。-试点项目和支持概念、规格、评估和演示进展的冠军用户。允许算法在数据源(选定的源)上运行的软件包装器-访问科学、公共和商业数据集；最后一个是通过采购和谈判。--国家环境研究中心社区环境数据中心及其环境数据服务处，专门为UKEO气候信息服务(UKEO CIS)的输出和耦合模式比较项目CMIP6的模型数据提供服务。通过提供共享的软件基础设施和用户服务，数据中心将设法解决用户社区所经历的数据获取和服务分散的问题。来自学术和商业部门的数据流将建立在以前英国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制作的数据集和英国特有的数据集；备受瞩目的气候模型模拟-CMIP和CORDEX；访问业务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、行业和政府用户达到1000+用户；与企业或国家利益攸关方开展五项具有影响力的大型活动；每年支持至少10家中小企业和10名政府用户。

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.
