Data model

Linear description of the Ile-de-France rail network, highlighting Public Transport lines subsidized by Ile-de-France Mobilités.


The sources of this data are the elements transmitted by the carriers, as well as IGN's BD TOPO and aerial photography for non-underground sections.


Wherever possible, inaccuracies have been rectified, enabling this data to be used as a reference. Linears are duplicated and superimposed when several lines use the same sections. An object describes all or part of a commercial line. Lines are truncated between each station, and at intersections of several lines (forks).
