The prolific growth in multi-story buildings in Victoria, Australia challenges the efficiency of 2D land administration system in dealing with spatially complex situations. Therefore, 3D digital approaches are being investigated to facilitate the management of rights, restrictions and responsibilities (RRRs) in cities. Previous research has focused on providing a general framework for 3D urban land administration. Generally, the main components are data capturing, data integration and modelling, validation, visualisation and spatial analysis. In order to provide future steps towards realising the 3D-enabled land administration system, an exact framework is also needed for each component; however, there is no comprehensive research to identify all the spatial analysis requirements and provide a general pathway for creating a unified spatial analysis system in urban land administration. Developing efficient mechanisms for spatial analysis can unlock the value of 3D RRR data, which would subsequently improve decision-making in complex urban environments. Therefore, this study provides a framework for spatial analysis in 3D urban land administration system. The paper’s methodology utilises a case study approach in which the existing regulations and legislations are investigated to identify the required spatial analysis. Then the capabilities of current 3D analytical approaches in terms of addressing regulatory requirements are assessed in order to gain a general view of the research gaps. By considering the identified 3D analytical requirements and knowledge gaps, a framework for spatial analysis will be provided.

澳大利亚维多利亚多层建筑的大量增长对二维土地管理系统在处理空间复杂情况方面的效率提出了挑战。因此，正在研究 3D 数字方法以促进城市中权利、限制和责任 (RRR) 的管理。以前的研究主要集中在为 3D 城市土地管理提供一个总体框架。通常，主要组件是数据捕获、数据集成和建模、验证、可视化和空间分析。为了提供实现支持 3D 的土地管理系统的未来步骤，每个组件还需要一个精确的框架；然而，没有全面的研究来确定所有空间分析要求，并为在城市土地管理中创建统一的空间分析系统提供一般途径。开发有效的空间分析机制可以释放 3D RRR 数据的价值，从而改善复杂城市环境中的决策。因此，本研究为 3D 城市土地管理系统中的空间分析提供了一个框架。本文的方法论采用案例研究方法，其中调查现有法规和立法以确定所需的空间分析。然后评估当前 3D 分析方法在满足监管要求方面的能力，以获得对研究差距的总体看法。
