LiDAR Breaklines

Breaklines are collected in areas where the bare-earth surface LiDAR needs additional definition, like top of banks, hydrologic features and major roads. The 3D breaklines Esri shapefile consists of: streams, lakes, rivers, major roads and other breaklines. The horizontal datum used is the North American 1983 HARN. The vertical datum is the North American Vertical Datum of 1988. The projection is Illinois State Plane, Eastern Zone, using US Survey Feet as units.
