Geospatial data and information within contemporary land administration systems are fundamental to manage the territory adequately. 3D land administration systems, often addressed as 3D cadastre, promise several benefits, particularly in managing today’s complex built environment, but these are currently still non-existent in their full capacity. The development of any complex information and administration system, such as a land administration system, is time-consuming and costly, particularly during the phase of evaluation and testing. In this regard, the process of implementing such systems may benefit from using synthetic data. In this study, the method for simulating the 3D cadastral dataset is presented and discussed. The dataset is generated using a procedural modelling method, referenced to real cadastral data for the Slovenian territory and stored in a spatial database management system (DBMS) that supports storage of 3D spatial data. Spatial queries, related to 3D cadastral data management, are used to evaluate the database performance and storage characteristics, and 3D visualisation options. The results of the study show that the method is feasible for the simulation of large-scale 3D cadastral datasets. Using the developed spatial queries and their performance analysis, we demonstrate the importance of the simulated dataset for developing efficient 3D cadastral data management processes.

使用过程建模模拟大规模3D地籍数据集

当代土地管理系统中的地理空间数据和信息对于充分管理领土至关重要。3D土地管理系统（通常被称为3D地籍）带来了许多好处，尤其是在管理当今复杂的建筑环境方面，但目前它们的全部功能仍然不存在。任何复杂的信息和管理系统（例如土地管理系统）的开发都是耗时且昂贵的，尤其是在评估和测试阶段。就这一点而言，实施此类系统的过程可受益于使用综合数据。在这项研究中，提出并讨论了用于模拟3D地籍数据集的方法。该数据集是使用过程建模方法生成的，引用斯洛文尼亚领土的真实地籍数据，并存储在支持3D空间数据存储的空间数据库管理系统（DBMS）中。与3D地籍数据管理相关的空间查询用于评估数据库性能和存储特性以及3D可视化选项。研究结果表明，该方法对大型3D地籍数据集的模拟是可行的。使用开发的空间查询及其性能分析，我们证明了模拟数据集对于开发有效的3D地籍数据管理过程的重要性。和3D可视化选项。研究结果表明，该方法对大型3D地籍数据集的模拟是可行的。使用开发的空间查询及其性能分析，我们证明了模拟数据集对于开发有效的3D地籍数据管理过程的重要性。和3D可视化选项。研究结果表明，该方法对大型3D地籍数据集的模拟是可行的。使用开发的空间查询及其性能分析，我们证明了模拟数据集对于开发有效的3D地籍数据管理过程的重要性。
