List of tools used in this presentation:

  • Read Points – Reliability attribute is selected at import.
  • Display Mode – Low reliability points displayed by coloring, the remaining points display in grey scale. Remaining points represent the ground surface.
  • Ground classification macro using reliability attribute reviewed:
  • Create Editable Model – Create model based on the classified ground points derived from the previous macro steps
  • Display shaded surface – View the ground model
  • Vegetation classification macro used to classify vegetation by height.
