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
