18 Laser Scanning Benefits

19 Laser Scanning Benefits Speed Hand Tape multiple personnel 100s of points per day Total Station 1 or 2 personnel 500+ points per day GPS 1 or more personnel points per day Laser Scanning 1 personnel 100,000+ points per second

20 Laser Scanning Benefits Speed

21 Laser Scanning Benefits Accuracy Anywhere from 5 microns (1/20 the thickness of an average sheet of paper) to 1 cm (for large volume scanning).

22 Laser Scanning Benefits Safety Laser scanners can be operated remotely, allowing personnel to remain safely on the ground.

23 Laser Scanning Benefits Safety Laser scanning is a non-contact measurement system. Features can be recorded without disturbing fragile material.
