Viewing the SNCF Reseau data assets in a Geographic Information System managed under Esri allows the better decision making. The numerous "data pools" are connected by API to facilitate their use by all potential users, the technical possibilities being optimized before the definition of uses.
Samuel Descroix, Manager of Geographic & Analytical Data of SNCF Reseau, has as a major role to promote an important data heritage.
35,000 kilometers of active lines on the national territory where 16,000 trains run per day, to which are added the lines of interesttechnical (service to technicentres, etc.): this is the domain of SNCF Reseau. This company resulting from the most recent reform is in charge of the management of the railway infrastructure, its construction, its maintenance, its operation and its equitable provision to all rail transport operators.
A few railway lines, with local services or within port rights-of-way in particular, fall outside its scope and it is also necessary to add lines which are no longer recorded because they are no longer operated and no longer maintained. To carry out its missions, SNCF Reseau needs a considerable amount of data to be used efficiently. This is the role of Samuel Descroix, Geographic & Analytical Data Manager of SNCF Reseau. It should be noted, before continuing, that the Gares & Connexions subsidiary of SNCF Reseau is, from an information system point of view, quite separate.
