Dtm Pyramidal Mlesac Fit

Plugin : SimpleForest
Nom de classe : SF_StepDTM

Description

Dtm Pyramidal Mlesac Fit - uses a pyramidal paralell plane fitting approach on a robust downscaled input ground cloud.

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 :

  • First the cloud is downscaled to a [voxel size] of 0.050 (m)..

  • For each of the downscaled points its normal is computed with a [search range] of 0.200 (m). .

  • The final [cell size] of the DTM is supposed to be 0.200 (m)..

  • The [angle] between a plane normal and the parent plane normal has to be smaller than 20.0 (°)..
