中国国土资源知识图谱数据(2022年)
收藏资源简介:
为解决国土资源不同数据产品间难以有效管理与快速应用的问题,利用图数据库对GlobaLand30、FROM-GLC10_2017、GLC_FCS30-2020 等公开土地覆盖数据集进行语义层面的结构化存储,建立中国国土资源知识图谱,为中国国土资源数据的管理、快速应用、数据质量评估等提供了一种新的处理框架。利用行政区划为单位的土地覆盖数据产品管理、知识提取以及数据获取与更新的新型应用框架,形成了447 817 个节点,447 816 条关系的可动态更新的中国国土资源知识图谱。
To address the challenges of inefficient management and rapid application difficulties among diverse land and resources data products, this study employs graph databases to perform semantic-structured storage for publicly available land cover datasets including GlobaLand30, FROM-GLC10_2017, and GLC_FCS30-2020, thereby establishing a knowledge graph for China's land and resources. This work provides a novel processing framework for the management, rapid application, and data quality assessment of China's land and resources data. By leveraging a novel application framework that takes administrative divisions as the management units for land cover data product management, knowledge extraction, data acquisition and update, a dynamically updatable knowledge graph for China's land and resources is constructed, which contains 447,817 nodes and 447,816 relationships.
