The CRENAU team of the AAU lab (http://aau.archi.fr/) of Ecole Centrale de Nantes works on
urban environnement perception.
We propose a PhD student position in urban data viz (see attachement for details), with
IRCCYN lab (http://www.irccyn.ec-nantes.fr/ <http://www.irccyn.ec-nantes.fr/fr/> ).
We are looking for student interested in urba data perception, user experience and a
multidisciplinary research environment.

PhD proposal – VisUrba project
Visualization of multi layered spatio-‐temporal 3D urban datasets
Keywords: urban data, geovisualisation, user study
Background, Context:
The understanding of complex spatio-‐temporal urban data is a critical challenge in urban
planning as the stakeholders have to take into account numerous constraints related to
various domains embedding sustainable, social and economical concerns.
To tackle this problem, geovisualization uses methods based on human perception and
cognition to show the underlying meaning of spatio-‐temporal datasets. This PhD thesis
proposes to explore visualization methods in various 3D environments (Desktop, VR, AR,
SAR) to find the best solution for a given user task (exploration, decision) at a given
urban scale (building, street, district, etc.).
This PhD in information visualization takes place into an pluridisciplinary environment
(computer science, geoinformation, humanities): the CRENAU team of the AAU lab (
<http://crenau.archi.fr/)%2Cwhich> http://crenau.archi.fr/),which is a founding
member of the IRSTV research institute (www.irstv.fr), and the IVC team of the IRCCyN lab
( <http://www.irccyn.ec-/> http://www.irccyn.ec-‐ nantes.fr/fr/equipes/ivc).
Research subject, work plan:
The work is about displaying spatio-‐temporal urban data in an effective way. Based on
the user's profile, behavior and task, the most appropriate visualization type and
data quality will be estimated. More precisely, this PhD thesis proposes to consider each
data as a layer that will be processed according to the data type and the required levels
of detail as well as the display context. The data model will be based on standards
currently used in GIS and/or BIM communities. User tests will be conducted to evaluate
the quality of proposed solutions. The research challenges include both visualization
solution proposal and the construction of an evaluation framework for information
visualization.
