This paper presents a third, subsequent, experiment to assess the performance of various visual variables for better visualization of 3D cadastre models. The case study is a 3D spatial representation of an apartment building with co-ownership units. The third experiment focuses on the following hypotheses “Transparency is performing to distinguish two groups of bounding objects such as physical (e.g., walls) and legal (administrative units) and to give the impression of ownership”. These objects are distinct and essential for use by notaries, one category of user of 3D cadastre models, since the spatial relationships between them may directly influence the determination of ownership, and the associated rights and responsibilities. The methodology is based on online questionnaire showing twelve 3D models where participants are invited to test their ability to decide if the wall of a specific apartment belonged to them or not. For data analysis, groups of participants are categorized according to being skilled in cadastral data manipulation, and in 3D data visualization. This paper presents preliminary results of those tests.
