摘要:

地理实体建模作为实景三维中国建设的核心任务和关键内容,是对现实世界中的几何空间及其关联的属性、关系进行抽象和数字化并建立实景三维模型的过程。从实景三维中国建设与应用视角对地理实体建模技术和方法进行了深入思考和总结:分二维平面、三维表面、实景三维3个阶段梳理了地理实体建模的发展演进过程;阐述了实景三维地理实体建模的内涵与外延,并回顾了地理实体建模的研究进展,包括地理实体几何建模、属性建模、关系建模和时序建模;以地理实体时序管理、时空关联技术应用为例,介绍了实景三维地理实体建模应用情况;围绕地理实体跨域协同交互融合建模、全空间一体化统一建模、多粒度全景化关联建模、自适应智能化时序建模等方向,对实景三维地理建模技术进行了展望。

Abstract:

Geographic entity modeling is a central task and crucial component in 3D realistic geospatial scene reconstruction of China. It involves the abstraction and digitization of real-world geometric spaces, along with its associated attributes and relationships, to generate 3D realistic geospatial scene model. Firstly, geographic entity modeling techniques and methods are thoroughly considered and summarized from the perspective of the construction and application in the 3D realistic geospatial scene of China. The evolution of geographic entity modeling is outlined across three stages: two-dimensional plane, three-dimensional surface, and 3D realistic geospatial scene. Secondly, this paper elaborates on the connotation and extension of the 3D realistic geospatial scene geographic entity modeling. Reviewing research progress in geographic entity modeling, including geometric modeling, attribute modeling, relationship modeling, and temporal modeling in geographic entities. Then, taking the temporal management for geographic entities and the application of spatiotemporal association techniques as examples, the application of 3D realistic geospatial scene geographic entity modeling is presented. Finally, this paper explores future directions for 3D realistic geospatial scene geographic modeling technology, focusing on cross-domain collaborative interaction fusion modeling, pan-spatial integrated and unified modelling, multi-granularity panoramic association modelling, and adaptive intelligent temporal modeling.

Key words: geographic entity, 3D realistic geospatial scene, geographic entity modeling, semantic modeling
