I have LiDAR data at 2m posting for two sites and have surveyed both sites with GPS at 1m posting including all features present. I want to use breaklines created from the features in the GPS survey on the LiDAR data without introducing the height values associated with the breaklines. I'm trying to do this so i can identify and map trench features in the LiDAR data that is not visible at this point in time. If anyone has any advice or feedback it would be greatly appreciated.
