Filter By Min Height
Plugin : SimpleForestNom de classe : SF_StepFilterByMinHeight
Description
Ground - This filter imports a DTM and input clouds. For each input cloud the point with minimal z coordinate is estimated. If this point has a distance larger than a user given treshold from the DTM, the cloud is removed.
