What is Terrestrial Laser Scan
4

• Why Terrestrial Laser Scan
• Increasing in the request for 3D digital city
  model
• Need for more precise and real 3D model
• The demand for more detailed and realistic
  models to improve participatory in Urban Planning

5

• Productivity
• Up to 50 km per day in urban areas
• Up to 100 km per day in extra-urban areas
• 1 day post-processing for every 5 days of data
  capture with geo referenced images and point
  clouds
• 0,5 to 2 hours work for data input per kilometer
  to carry out a full GIS database

• Results and deliverables
• Routes
• Pavements
• Vertical signs
• Traffic markings (automatically detected by the
  reflectance)
• Sidewalks and building facades
• Slopes
• Retaining walls and shoulders
• Tunnels and bridges
• guard rails

• Point cloud overlap on images
• Stereoscopic Photogrammetry
• Measurements can be taken by snapping on
  laser points
• Cross section of the infrastructure
• Export point clouds and cross- sections in CAD
  format
• Geo database of all road information

• TRANSVERSAL PROFILES AND MEASUREMENTS
  PERPENDICULAR TO THE ROAD !!!

• Summary Outlook
• Terrestrial Laser scan necessary tools role in
  Road Scanning
• The outcome result of different projects show
  the suitability of the Terrestrial LS in Road
  Scanning
• The demand for detailed 3D city models can be
  well done through Terrestrial LS
• Urban Planner should consider the new
  Terrestrial LS applications and profit from it
