地球观测组织在第十六届全会和部长级峰会上提出了构建“对地观测应用数字图书馆”的新目标,强调从“推动开放数据”向“推动开放科学”的深入,旨在完成数据、算法、文献、案例等知识资源的管理和共享,进一步推动地球观测在全球变化等领域的全面应用和知识服务。该文以此为研究背景,详细梳理了地球科学变量概念体系、地球观测卫星和载荷、观测和模拟数据产品以及学术文献开放知识库等地球观测数据资源。基于语义网和知识图谱相关的理论和技术,构建了包含地球科学变量、遥感卫星、观测载荷、观测和模拟数据集、期刊和学术文献共6类地球观测知识本体和实例。该研究的知识表达结果将有助于地球观测应用领域数据和知识的表达、管理和集成,有助于发现数据和知识的潜在关联,提高科研效率,促进科学发现。

At its 16th Plenary Session and Ministerial Summit, the Group on Earth Observations (GEO) proposed a new goal to build a “digital library for Earth observation applications”, highlighting the transition from “open data” to “open science”. It aims to achieve the management and sharing of knowledge resources, including data, algorithms, literature, and cases, thereby facilitating the comprehensive application and knowledge service provision of Earth observations in fields such as global change. Under this research background, this study systematically examined Earth observation data resources, including the conceptual system of Earth science variables, Earth observation satellites and payloads, observational and simulated data products, and open knowledge bases of academic literature. Based on the theories and techniques related to the Semantic Web and Knowledge Graph, this study established the Earth observation knowledge ontology with corresponding instances, involving Earth science variables, remote sensing satellites, observation payloads, observational and simulated datasets, journals, and academic literature. The knowledge representation results of this study will contribute to the representation, management, and integration of data and knowledge in the field of Earth observation applications. Moreover, they facilitate the discovery of potential associations between data and knowledge, enhancing the efficiency of scientific research and advancing scientific discovery.
