Terrain Following in Survey Mission

[chris89116]

Is it possible to fly a survey mission while using an on-board laser rangefinder to follow terrain ? My mission requires flight at low altitude with tight altitude compliance over rolling terrain. I have experimented using the DEM terrain height but it is just not accurate enough, even using 1 meter DEM data.
