Terrestrial laser scanning provides highly accurate,  three-dimensional images enabling designers to experience and work  directly with real-world conditions by viewing and manipulating rich  point-clouds in computer-aided design software.  By sweeping a laser  beam over a scene or object, the laser scanner is able to record  millions of 3D points.  

These X,Y,Z measurements can be imported into  CAD or 3D application software and displayed on a computer monitor as a  'point cloud' which has photographic qualities portrayed in one-color,  gray-scale, false-color or even true color.  Since all laser scan points  are 3D, the files can be viewed, navigated, measured and analyzed as 3D  models.  

Benefits of laser scanning:

  • Speed of data capture - reduces time and cost.  
  • Remote acquisition and measurement - increases efficiency and safety of surveys.  
  • High point density data ensures a complete survey.  
  • Abundance of data captured in laser scanning reduces questionable  data, provides oversampling to ensure accuracy and that all objects,  structures, geometry are captured.  
  • High-density, accurate data are direct measurements.  
  • Imagery and 3D visualization provides added confidence that mapped objects correspond to actual existing conditions.
