LAStools LiDAR classification workflow

Threw this together for easy reference, as I spend a lot of time with unclassified point clouds and I can't be the only one who wished for a cheatsheet the first couple times through. The full tutorial by Isenburg himself can be found here. These should be used together with the ReadMe files (it's really just a case of fiddling with parameters until you find the sweet spot)... this is just a reminder of the basic steps.

mkdir CityGround

lasground -i CityTiles\*.las -odir CityGround

mkdir CityHeight

lasheight -i CityGround\*.las -odir CityHeight

mkdir -i CityClassed

lasclassify -i CityHeight\*.las -odir CityClassed

Helpful tools along the way:
lasview -i *****.las
lasinfo -i *****.las
