摘要
本文对BIM模型进行解析,提出LOD4层次的建筑信息,将家住信息转换到GML模型中,构建室内拓扑信息,与IndoorGML模型相结合建立室内拓扑信息。借助BIM技术构建室内二维连通网络,对室内空间三维剖分后满足新的三维GIS需求,为室内导航、路径分析等应用提供技术支持。
This paper analyzes the BIM model,puts forward LOD4 levels of building information,converts home information into GML model,constructs indoor topology information,combines with IndoorGML model to establish indoor topology information,constructs indoor two-dimensional connected network with the help of BIM technology,meets the new three-dimensional GIS requirements after three-dimensional subdivision of indoor space,and provides technical support for indoor navigation,path analysis and other applications.
