3D Laser Scanning

3D Laser Scanning: High-Definition Survey
"3D Laser Scanning: An 'Ultra-Fast, High-Definition, Reflectorless Topographic Survey,'" was written by Geoff Jacobs and published in the May 2004 issue of Professional Surveyor Magazine.
Article Excerpt:

"Since 3D laser scanning technology first splashed onto the scene in 1998, professionals have had varying interpretations about what makes this technology different from others. Some have focused on its speed, “imagine capturing 1,000 points per second!” Others focused on its 3D aspects, heralding 'the dawn of 3D surveying' (not!). Still others zeroed in on its remote measurement capabilities, labeling it for inaccessible or unsafe sites. And still others focused on its colorful, informative images."

The fact is that 3D laser scanning is about all of those things and more. Fundamentally, however, its single most important and differentiating technical aspect is its high point density. With high point density as 'the primary driver,' its other key features are natural companions."
