SNCF has used FIT ESIC’s rail-mounted StreetMapper to improve safety and inform track upgrade works. StreetMapper was used to survey several hundreds of kilometres of track, generating engineering-grade survey data on behalf of SNCF. The data generated from the millions of individual laser-scanned measurements include a 3D topographic map of the track and its surroundings, including power lines, stations and trackside equipment.
