Legal boundaries are used for delineating the spatial extent of ownership property’s *** underground environments,these boundaries are defined by referencing physical objects,surveying measurements,or ***,there is a gap in connecting and managing these boundaries and underground legal spaces,due to a lack of data model.A 3D data model supporting underground land administration(ULA)should define and model these boundaries and the relationships between them and underground ownership *** 3D data models can be enriched to model underground legal *** research aims to propose a new taxonomy of underground legal boundaries and model them by extending CityGML,which is a widely used 3D data model in the geospatial science *** developed,implemented,and tested the model for different types of underground legal *** implemented prototype showcased the potential benefits of CityGML for managing underground legal boundaries in *** proposed 3D underground model can be used to address current challenges associated with communicating and managing legal boundaries in underground *** this data model was specifically developed for Victoria,Australia,the proposed model and approach can be used and replicated in other jurisdictions by adjusting the data requirements for underground legal boundaries.
