Also, lake surfaces are smoothed and stream courses are conditioned for downhill flow using breakline data. This subset of the processed returns from the airborne laser sensor represent the ground surface and is commonly referred to as the \u2018Bare Earth\u2019 point cloud.<\/span>", "summary": "This is a digital terrain model image based upon the Lidar collected in April 2021.
