A LIDAR SCAN PROVIDES THE ABILITY TO DIGITALLY REVISIT THE SITE ANYTIME USING A COMBINATION OF PHOTOGRAPHIC IMAGERY AND A 3D POINT CLOUD
Lidar instruments capture hundreds of thousands of 3D points per second. These points are colored by intensity of reflection or by the color of the reflected object. 
Ollerhead & Associates Ltd. can provide Terrestrial & Aerial Lidar Scanning to numerous industries such as Engineering, Construction, Mining, Architecture, Forensics, and Archaeology. Specific applications include:
- High Density Topographic Surveys
- High Precision Volumetric Surveys
- Detailed Construction and Infrastructure As-builts
- Deformation Monitoring
- Complex Plant Site As-builts
Lidar Scanning is advantageous when detail and speed is a priority or direct site access is not possible. Situations where Lidar Scanning is preferred are:
- Complex Surfaces
- High detail requirements
- Difficult or unsafe site access
- Congested or high traffic areas
- Delicate or inaccessible surfaces
- Short time frames for significant detail
- Flexibility to reuse data in the future
