本文提出了一种比较地籍管理系统的原始方法，更具体地说，是用于在空间上表示垂直分割共同所有权（通常相当于公寓）的概念模型。该比较基于 ISO 19152 土地管理域模型 (LADM) 规范，这是 ISO 最近采用的一项国际标准。 LADM 比较适用于魁北克（加拿大）和阿尔萨斯摩泽尔（法国）公寓单元。特别关注每个辖区使用的空间表示的第三个几何维度。该研究包括为魁北克和阿尔萨斯摩泽尔的公寓单元创建 LADM 布局并进行比较分析。本文讨论了使用 LADM 布局进行此类比较的优点和局限性，并提出了为其他地籍系统进行类似分析的建议。 LADM 模式化无疑使魁北克和法国公寓单元之间的比较变得更容易、更简洁和更清晰。对常见概念和术语（例如 LADM 提出的）的正式描述使我们能够量化相似性和差异，并有可能朝着在两个系统之间“自动”创建匹配文件的方向发展。主要优点之一是由模式化过程产生的图形视图，允许视觉比较，现在可以并排比较两个系统，逐个类，逐个属性地进行比较。然而，LADM 规范的使用并不明显，并且需要相当多的数据建模技能。 LADM 文档有些技术性，缺乏官方定义。理解文档需要时间，并且某些 LADM 类、属性或关系不明确，仍然难以与两个系统匹配。
This paper proposes an original approach for comparing cadastral management systems, more specifically, the conceptual modeling used to spatially represent vertical divided co-ownership (usually equivalent to the condominium). The comparison is based on the ISO 19152 Land Administration Domain Model (LADM) specification, an international standard recently adopted by ISO. The LADM comparison is applied between Quebec (Canada) and Alsace Moselle (France) condominium units. Specific attention is paid to the third geometric dimension of the spatial representation used in each jurisdiction. The study includes the creation of LADM layouts for condominium units in Quebec and Alsace Moselle and a comparative analysis. The paper discusses the advantages and limitations of using LADM layouts to undertake such comparisons and gives advices to produce similar analysis for others cadastral systems. LADM schematization certainly made the comparison between Quebec and French condominium units easier, more concise and clearer. The formal description of common set of concepts and terms such as proposed by LADM allows us to quantify the similarities and differences, and potentially move towards the “automatic” creation of a matching file between both systems. One of the main advantages is the graphical views resulting from the schematization process that permit visual comparison where both systems can now be compared side by side, class by class, attribute by attribute. The use of the LADM specification is, however, not evident and requires quite a few skills in data modeling. The LADM documentation is somewhat technical and lacking in official definition. It required time to comprehend the documentation, and some LADM classes, attributes or relationships are ambiguous and still difficult to match with both systems.
