Extracting from Point Clouds

Points, Lines, Surfaces, Features and Models
"Extracting Points, Lines, Surfaces, Features & Models from Point Clouds," was published in the September 2004 issue of the Professional Surveyor magazine and written by Geoff Jacobs.
"In an earlier, introductory article on high-definition surveying (3D laser scanning), it was pointed out that its single most important, distinguishing feature is its high point density (May 2004). Other key features—high-speed data capture, reflectorless measurement, 3D visualization, and colorful imagery—can be considered bonus by-products of the technology's focus on economically capturing a site or structure with high point density. The potential advantages of dense point data, such as creating more complete and accurate as-builts, have also been covered in earlier articles (May, July, and August 2004). High point density, however, raises some interesting new questions—and opportunities— regarding the task of extracting traditional deliverables."
