- PublicationRestreintGeoWeb and crisis management : issues and perspectives of volunteered geographic information(Springer, 2011-07-28) Mericskay, Boris; Propeck-Zimmermann, Eliane; Roche, StéphaneMapping, and more generally geopositioning, has become ubiquitous on the Internet. This democratization of geomatics through the GeoWeb results in the emergence of a new form of mapping based on Web 2.0 technologies. Described as Webmapping 2.0, it is especially characterized by high interactivity and geolocation-based contents generated by users. A series of recent events (hurricanes, earthquakes, pandemics) have urged the development of numerous mapping Web applications intended to provide information to the public, and encourage their contribution to support crisis management. This new way to produce and spread geographic information in times of crisis brings up many questions and new potentials with regard to urgency services, Non Governmental Organisations (NGO), as well as individuals. This paper aims at putting into perspective the development of GeoWeb, both in terms of technologies and applications, against crisis management processes.
- PublicationRestreintGeographic information science : why does a smart city need to be spatially enabled?(Sage, 2014-02-07) Roche, StéphaneIn this report I propose to examine the concept of the ‘smart city’ from the standpoint of spatial enablement. I analyse emerging research on smart cities, particularly those addressing the potential role of GISciences in the development and implementation of the concept of smart cities. I develop the idea that the intelligence of a city should be measured by its ability to produce favourable conditions to get urban operators (citizens, organizations, private companies, etc.) actively involved into sociospatial innovation dynamics. To obtain such a commitment, I believe that operators should be able to develop and mobilize (digital) spatial skills so that they could efficiently manage their spatiality. In other words, I argue that a smart city is first of all a spatially enabled city.
- PublicationRestreintGeographic information science II : less space, more places in smart cities(Sage, 2015-05-19) Roche, StéphaneThis second report is dedicated to the concept of ‘place’ revisited in the context of smart cities. Some recent studies suggest that today’s digital cities rely more on an approach to the urban context based on a network of connected places than on an approach to the city built on areal spaces. Does it mean that there are more places and fewer spaces in spatially enabled cities? Is the intelligence of a city mainly related to its ability to sound out the genesis of urban places? These issues raise questions about the design of spatial models used to build GIS, as well as place-based urban design methods and tools. This second report explores these questions from the standpoint of GISciences.
