Cover Story: Since the appearance of Spatial Data Infrastructure (SDI), there has been an increase in spatial data available on the web. This situation raises research issues, in terms of identifying the content actually accessible and its impact on local governance. Our study proposes a mixed methodology applied to 45 French infrastructures, to compare the objectives stated by their promoters and their actual content. The methodology, based on an analysis of interviews with SDI coordinators, as well as an exploration of over 160,000 metadata in their catalogues, produced results concerning data accessibility, stakeholder networks, the interoperability of tools, and informational equality. Despite the proactive stance of SDI promoters, only 16% of data are open-access. Their interoperability remains restricted to specific types of actors. Although geocollaboration organised by SDIs is very active, it only concerns the public sector. These disparities also concern their spatial distribution.
