I have LiDAR and derived data in UTM18N meters, NAVD 1988 meters. I want to convert it to Maryland State Plane 1983 feet with NAVD 1988 feet. Is this not possible or am I doing something incorrectly? It seems I can get the x,y but not the z to change in a multipoint las derived file. I just need to get the .las files over to a dem in Maryland State Plane 1983 feet, NAVD 1988 feet file to derive other outputs.
