SUMMARY:Revealing past railway networks from OSM data - Robert Jeansoulin

DESCRIPTION:Many "way" elements in OSM are tagged "railway." OpenRailwayMa
 p builds upon them\, adding numerous details. However\, the lack of "relat
 ion"\, between "ways" no longer used as railways\, hinders the analysis of
  abandoned lines. Knowledge from the realm of Volunteer Geographic Informa
 tion can bring the missing link\, while leveraging the accuracy of OSM dat
 a. This article aims to add nodes of thousands forgotten stations\, and to
  fill hundreds gaps between scattered OSM elements\, which are unaware of 
 their former railway line affiliation. The experiment covers almost entire
  old railway networks of France and Belgium.
