The CNRS thematic school “See or being seen… or not 2017” will take place from the 23th to the 27th october 2017. This thematic school tackles the topic of visibility analysis dedicated to the understanding of urban morphology. Visibility analysis is considered in all its forms, such as ground and sky view analysis, detection of salient features and solar insolation simulation. These analysis may be automatized or manual, processed in situ or in a virtual universe.

The aims of this event is to gather researchers and practitioners from different communities (architecture, geomatics, geography, computer sciences) in order to exchange about proposed methods from these domains and to discuss about a common topic. For the support of the discussions, the different methodologies presented during the week will be processed on a common study zone on which a group work will be lead about a urban planning issue.


The urban landscape analysis portrays a key issue to study the consequences of the urban development. It helps indeed to assess environmental indicators, to measure impact of the urban shape on the inhabitants, or to understand the organisation of urban frameworks. To conduct in-depth analysis, various approaches exists based on visibility assessment methods such as: sun views (solar insolation/shading) revealing access to sunlight and solar rights; sky openness and sky views as skeleton/indicators of the sensitive density of surroundings building facades (to estimate the oppressiveness of streetscapes as an example), skyline analysis as dimension of the urban landscape, etc. All these methods have been identified, in the state of the art, as effective tools to regulate morphology in the urban project context. Nowadays, strong scientific breakthroughs have been achieved in computer vision, in visual analytics, and in geo-information sciences that suggest that a convergence between software tools and in-situ processing methods is possible (in architectural field, in city planning and urban development, and in the geography field). The increasing availability of 3D fine-grain dataset supplements these significant headway. In order to gather these communities, but also to identify, delineate, and structure this new thematic body of knowledge, a strong involvement of actors seems to be obvious which justifies that a dedicated thematic school shall be prepared.


This fully pluridisciplinar school is intented for a various audience. It may interest students or researchers in architecture, urban planning, geomatics or computer science, who are concerned by morphological analysis.
