Platte River Channel, Nebraska
LIDAR-derived binary (.las) files containing classified points of all returns. We have 3 classifications Unclassified, Ground, Low points. The average Ground Sample Distance (GSD) is 0.7 meters. The tiles are delivered in 2,500m by 2,500m tiles. These files are in ASPRS ver 1.1 format.
The Lidar data combined with the 3d breaklines can be used to produce a highly accurate representation of the earth's surface (x, y and z).
