The LIDAR data encompassed the area around York Street where the junction of the M2, M3 and Westlink converge. The LIDAR survey was carried out to enable measurement of elevation on the York Street Interchange scheme. The raw LIDAR data is a series of points stored as x, y, z where x and y are longitude and latitude; z is the elevation in meters or feet. The survey was carried out between July and September 2012 by Fugro-BKS Limited on behalf of DfI Roads to aid the design of the Interchange scheme at York Street.
