best lasground setting for AUV point cloud

[Alessandro Montaghi]

Hi all, 

I am reading the setting parameters example on lastools about lasground. I am working on two areas: one forested with some open spaces and one is a prairie landscape.

The lastools example suggest: Note that lasground was designed forairborne LiDAR. When using lasground with terrestrial or with mobile data play with the '-not_airborne' option (which may work better) or try the '-no_stddev' or '-no_bulge' flags.

Is it valid also for AUV point cloud?

Second. For the forested area i used 

-all_returns 

-wilderness 

-ultra_fine 

-spike 1 

-replace_z 

-cores 4

for the prairie area is it better to use -town and -course following the example:

The default step size is 5 meters, which is good for forest or mountains. For towns or flat terrains '-town' the step size is increased to 10 meters.

for flat terrains you can simplify the search with '-coarse' or '-extra_coarse' but try the default setting first. 

Thanks for all suggestions.

Ale
