Amtrak’s New York Penn Station (NYPS) mobile surveying project was one of the first extended mobile LiDAR projects completed underground. Mobile LiDAR technology was requested to provide a seamless 3D survey data set across the station’s rail infrastructure systems and to locate all visible ancillary features throughout the underground facility where GPS data isn’t available and do so without disrupting passenger train service.
Amtrak’s NYPS is the main intercity railroad station located in Midtown Manhattan. The station is located entirely underground beneath Madison Square Garden with its 21 tracks, 11 platforms and 7 connecting tunnels. The project spans from the station side portals of the 2 Hudson River tunnels, through the station’s 21 tracks and 11 platforms, and to the station side portals of the 4 East River tunnels.
