Research on the Specification for Representing Bridge Geographic Elements in High-Precision Digital Maps for Highways

Le résumé fourni par la source

This paper delves into the research on standardized representation of highway bridges within the geospatial information context, aiming to establish a bridge data model tailored for applications in high-precision digital base maps. Initially, by analyzing the requirements for digital representation of bridges and integrating relevant design standards in geospatial information, a comprehensive bridge data model framework is proposed, encompassing attribute definition, geometric representation, and associative relationships, with clear specifications and expression requirements for each component. Subsequently, to facilitate efficient organization and retrieval of bridge data, a tailored table structure design scheme is devised. Ultimately, an efficient and secure data interface is developed for integration with bridge health monitoring systems, enabling real-time updates of dynamic attribute data.
