BIM及其轻量化技术在三维不动产登记中的应用OA

In response to the inherent challenges of traditional two-dimensional(2D)real estate registration models,such as unclear spatial information representation,fragmented and dispersed multi-source data,and low efficiency in data integra-tion,this paper innovatively proposes an optimized solution for three-dimensional(3D)real estate registration based on building information modeling(BIM)and lightweight processing technology.This solution constructs a refined 3D spatial model for property units,achieving precise spatial coupling of building entity shapes and ownership information.It also uti-lizes lightweight technology to deeply optimize the model,significantly improving system performance while ensuring geo-metric accuracy.This approach effectively addresses data redundancy and performance bottlenecks in 3D real estate registra-tion.The research validates the innovative value of BIM models in 3D visualization of property rights confirmation,auto-mated data extraction,parcel information querying,and multi-departmental collaborative applications.It provides a reusable technical paradigm for building 3D real estate registration systems and promotes the digital transformation of interdepartmen-tal business processes and urban spatial governance.
