Yes, lidar data are highly dense point data representing an x, y, z location, along with other attributes, of any terrestrial target reflecting the laser pulse. In addition to bare-earth, it typically will include buildings, trees, towers, and powerlines.
The NED data layers are bare-earth raster surfaces in raster digital elevation model (DEM) format. While many currently generated DEMs and much of the NED are produced from bare-earth lidar point data, the NED layers are not lidar.
