665 Mile Statewide Railway Scanning

In collaboration with the MDOT Survey Support Unit, Spicer Group completed a network-wide data collection project for the MDOT Office of Rail across its 665-mile railroad network in the Lower Peninsula. Various data collection technologies were used including Mobile Terrestrial LiDAR/rail-view imagery, Airborne LiDAR/ortho-imagery, UAV-acquired ortho-imagery, and traditional RTK GNSS surveying. All data was fused together using advanced data fusion techniques to create a network-wide geospatial dataset of all MDOT-owned railroad assets. The data was used to map the centerline of all railroad track owned by MDOT and extract milepost signs, points of switch, and points of frog. All extracted asset data was delivered in a standard file geodatabase to support the development of a railroad linear referencing system and integration into MDOT’s Transportation Asset Management System (TAMS).
