Filter By Min Height

Plugin : SimpleForest
Nom 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.

Paramètres

Paramètres de pré-configuration (non modifiables une fois l'étape ajoutée) :

  • Uncheck to deactivate parameterization possibilities of this step. Only recommended for beginners: Activé.

Paramètres de l'étape :

  • If a clouds lowest point is further away from the DTM than [maximal MinHeight] of 1.25 (m), the cloud is removed.
