Leica Geosystemsreleased theHDS6000 laser scanner and Cyclone SCAN v5.6, the companion software for controlling the new scanner. The HDS6000 features several major advances compared to the Leica HDS4500 scanner: 50% greater range, based on ambiguity interval; new compact design with scanner, scan control panel, data storage and battery integrated into a single unit; new tilt compensation that allows traversing and resectioning; three scanner control options; higher accuracy for each single point measurement; and twice the maximum scan density. The HDS4500 also features a full field-of-view (360º x 310º) design and a scan speed up to 500,000 pts/sec, which increases field productivity by reducing the number of separate scan targets needed during a high-definition survey.
