Research on Key Technologies for Geographic Information Database Construction
地理信息数据库建设关键技术研究

摘要

地理信息数据库是基础地理信息系统建设的核心，关键技术涵盖数据采集、存储管理、组织建模、质量控制、动 态更新与服务共享等环节。系统梳理了数据预处理、存储管理、空间建模、质量控制、动态更新及服务发布等核心技 术。当前自然资源时空数据管理技术在静态实体表达、结构化索引、同类型更新和二维存储方面已较为成熟，但在多 源融合、多模态建模和动态索引更新方面仍存在瓶颈。构建多模态、动态、精细化的数据管理技术体系是未来重点方向。

Abstract

Geographic information databases are the core of basic geographic information system construction, and their key technologies cover data acquisition, storage management, organizational modeling, quality control, dynamic updating, service sharing, and other links. This paper systematically reviews core technologies such as data preprocessing, storage management, spatial modeling, quality control, dynamic updating, and service publishing. At present, natural resources spatiotemporal data management technologies have become relatively mature in static entity representation, structured indexing, same-type updating, and two-dimensional storage. However, bottlenecks still exist in multi-source fusion, multimodal modeling, and dynamic index updating. The construction of a multimodal, dynamic, and refined data management technology system will be a key direction for future development.
