Research and practice on the construction for Construction of 3D real scene geo-entity data
The geo-entity serves as the core content of 3D real scene product construction and a vital spatio-temporal element that empowers natural resource management and economic-social development.This paper addresses the issues in the current applications of 3D real scene,including insufficient data fusion depth,limited data support capabilities,and difficulties in implementing application scenarios.It investigates the construction content,methods,and key technologies of the spatial,attribute,relational,and coding features of 3D real scene geographical entities from five spatio-temporal empowerment dimensions:spatio-temporal benchmarks,spatio-temporal correlation,spatio-temporal analysis,spatio-temporal intelligence,and spatio-temporal security.Taking the construction of a smart community application system as an example,this paper verifies that the 3D real scene geographic data constructed through this technology can effectively empower industry applications.It proposes a development approach to further promote spatio-temporal intelligence by extensively associating ubiquitous thematic information,real-time integrating IoT perception data,and continuously iterating relational knowledge.This paper provides reference and insights for the construction of 3D real scene data.
