Les Infrastructures de Données Géographiques (IDG) : développement d'une méthodologie pour l'étude des usages : le cas des acteurs côtiers et de la GIZC en France

Abstract : Spatial Data Infrastructures (SDIs) have been implemented over the last twenty years in particular in order to contribute to Environmental Policy by improving geographic information access and sharing processes. Given the current dynamics of both production and circulation of environmental geographic information, the general aim underlying this research is part of the general framework for a better understanding of environmental management practices. This research focuses specifically on French SDIs and their contribution to Integrated Coastal Zone Management (ICZM), a complex form of territorial governance for which the collection and sharing, particularly via SDIs, of geographic information have been identified, since the 2000s, as a major component on which to found coastal and marine public policies. However, the real contribution of SDIs depends on the answers they provide to their users. From a methodological perspective, this PhD is implemented by an exploratory research approach focusing on the usages and needs of coastal stakeholders as well as on the complex and dynamic nature of SDIs. The research approach is divided into two phases: - A national online survey examined by a triple analysis: Statistical analysis, Social Network Analysis (SNA) and thematic analysis;- A sub-national case study based on semi-structured interviews with key informants and analyzed thematically and by Data Flow Diagrams (DFD). These data collection and analysis techniques have been selected and implemented in an integrated and complementary approach to enable understanding, explanation and generalization of the "SDI system" in the context of ICZM. For each phase of the research, three types of results emerged: the profile of users, the type of SDIs playing a role in the management of French coasts, and their contribution to the management of these areas. The above-described research has resulted in a contribution to the knowledge of SDI appropriation and the associated information flows.
