EXEMPLARY PROJECT
In this project we applied aerial images and
MMS/MML System. Our MMS/MML holds 2D Scanner
(profiler) Riegl VQ 250, 2 3D scanners Riegl
VZ 400, 6 digital video cameras, Ground-penetr
ating radar from IDS, Positioning System
GPS/IMU Applanix POS LW 420 V.

EXEMPLARY PROJECT

• Data acquired
• Coherent point cloud from 3 scanners,
• Aerial photos with 5cm GSD (ground sample
  distance).
• End products
• 3D Vector Base map for design purposes, accuracy
  XY lt 3 cm, Z lt 1 cm,
• DTM (Digital Terrain Model) with accuracy 1 cm
  for the roadway and 20 cm for 250m buffer,
• Orthophoto with a 5cm pixel size (GSD).
• Vector Base map for design purposes has been made
  in 3 months for 85km of highway without stopping
  the traffic.

APPLICATION OF MLS/TLS IN FORESTRY

• Measuring directly on a point cloud
• Tree and stand basal area,
• diameter on any given height above the ground
  (including breast height)
• tree position
• tree height
• Extracting
• Stem volume
• Tree Biomass
• 3D surface of stems

SUMMARY

• Photogrammetrical measurements are faster than
  direct,
• Mobile Laser Scanning system allows for the
  measurement and mapping of objects at the level
  of precision which is not available for Airborne
  Laser Scanning (ALS),
• Integration of MMS/MLS/TLS with ALS or aerial
  images allows us to create a complete end
  product, mapped from different perspectives,
• Mobile Laser Scanning and Terrestrial Laser
  Scanning may be used in Forestry, although for
  big areas automatization would be desirable. The
  files coming from laser scanning are big. Post
  processing of them requires specialized software,
  high-end computer, knowledge and experience of
  the operator.
