French railway company SNCF has used FIT ESIC’s rail-mounted StreetMapper to improve safety and inform track upgrade works.
According to FIT ESIC, 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.
StreetMapper laser scanning system also provided length and cross profiles of the track, such as cantenary lines, contact lines and overhead civil engineering structures.
Designed for the rapid 3D mapping of highways, runways, railways, infrastructure and buildings, StreetMapper enables high-precision mapping to a range of 800m, with one sensor capable of 550,000 measurements a second.
FIT ESIC engineering division director Marc Daeffler said: "Since we took delivery of our StreetMapper system, we have surveyed thousands of kilometres of roads, as well as hundreds of kilometres of railway tracks.
"By working closely with various SNCF engineering teams, we came up with innovative solutions, utilising StreetMapper to capture and extract large amounts of geometric information."
