Mesurer les impacts des infrastructures de données géographiques (IDG) et des observatoires

Abstract

This paper analyses the economic effects generated by the SIG-LR Spatial Data Infrastructure (SDI) located in Languedoc-Roussillon region (France). From a literature review and the analysis of the functioning of SDI, a typology of SDI impacts was produced. A survey of 51 members of SIG-LR was used to measure the main effects in terms of employment, productivity gains and saving of inputs. In addition the survey also helped to characterize a beam of qualitative impacts in terms of diversification and quality of services, networking, transparency of information and impact on territorial governance. Knowing that the budget of SIG-LR is 0.9 million euros and that a total of 3.77 million euros of impacts has been measured, a ratio of one euro invested produces an economic impact of four euros within the SIG-LR community and the regional economy.
