SNCF Réseau is moving towards an enterprise-wide GIS to improve information sharing across the French railway organization. Key aspects of this transition include developing GIS projects and services, adopting a service-oriented architecture, and establishing shared data repositories and models. The goals are to rationalize costs, improve data quality and availability, and support new applications through reusable and standardized services and components built upon the Ariane reference model. This enterprise GIS approach aims to provide a unified view of railway business objects and processes to enhance operational piloting, analysis, and cross-domain collaboration.
