• Task 3: Considering a speciic lot, is it an administrative unit or the building itself?
• Task 4: Considering a speciic lot, is a private or a common part?
• Task 5: Which corners of the condo overlap the land parcel?
• Task 6: How many lots touch the lot presented in red (upper side and adjacent)?
The second group of questions is fully subjective and it examine the preference of
the notary between two visual solutions presented side by side. Only snapshots are
accessible for this second group of questions. The notaries are free to express any
or no preference.
As regards the sampling of notaries for these first tests, two factors have guided
our decision: (1) if the notaries already performed co-ownership establishment
about the condominium studied; and, (2) if notaries are interested in 3D cadastral
modelling. By now and because of the challenges of finding relevant case studies
and schedule appropriate notaries, only four notaries have been interviewed.
3 Analysis of the Results
Presentation of the full compilation extracted from the interviews would be too
lengthy to expose and not helpful to appreciate the results. To summarize, the fol-
lowing tables express the performance and the preference of the visual variable
and the enhancement techniques when at least 75 % (3 out of 4) of the responds
are consistent from one notary to another. Performance refers to the first group of
questions (i.e. when verification is possible), and preference refers to the profes-
sional opinion of the notaries. When no consistent result is observed, no conclu-
sion is marked in the table (Tables
1
and
2
).
Regardless of the small number of consistent results and of interviews, some
reports may be identified.
Color (hue)
: With or without transparency, the color (hue) is among the pre-
ferred and the better performing visual solutions compared to value and tex-
ture. The color (hue) was tested for tasks 1, 2 and 6 and was classified first in all
