Cut Cloud Above DTM

Plugin : SimpleForest
Nom de classe : SF_StepCutCloudAboveDTM

Description

Cut Cloud Above DTM - Takes an input Scene and a DTM model. Splits the scene into two clouds UPPER and LOWER. The user selects a threshold height and each point with a height below the threshold is put into cloud LOWER, into UPPPER otherwise.

Paramètres

Paramètres de l'étape :

  • Over the input cloud is iterated. For each point the height above the DTM is computed. If the height is lower than [threshold height]: 0.10 (m) .


the point is put into the lower cloud, otherwise into the upper cloud.
