What is LIDAR

LIght Detection And Ranging
LIDAR is a remote sensing technique that maps a 3 dimensional view of your property with a high degree of accuracy. 
The system is usually flown at 1-2,000 m above the ground and incorporates:-
  • airborne scanning laser rangefinder,
  • differential GPS, and
  • Inertial Navigation System   
Picture
The output from a LIDAR survey is a point cloud where every point has an x, y and z coordinate together with a number of attributes such as classification (building, ground, vegetation, water, etc), intensity, scan angle , return number, etc.
Other attributes can be calculated (height above ground) and RGB colours for every point can be merged from aerial photography. 

The following diagrams display LIDAR points in plan, section and oblique view coloured by attribute to give an indication of  what the raw data is like.
