Leica Geosystems news for topographic survey.....

23 July 2007, 4:39pm

Leica Geosystems today announced a major advance in the capabilities of pulsed (or “time-of-flight”) laser scanners for as-built and topographic surveys. Leica ScanStation 2 brings a significant productivity increase to the popular “ScanStation” class of scanner, already known for its versatility and friendliness. The maximum instantaneous scan speed for ScanStation 2 is 50,000 points/second, more than 10-times that of its ScanStation predecessor (4,000 points/second) and the highest in the industry for pulsed scanners.

While setting a new standard for scan speed in pulsed laser scanners, Leica ScanStation 2 retains the four fundamental total station features that defined ScanStation™ as a new category of laser scanner:

- Full 360º x 270º field-of-view (FOV)
- Survey-grade dual-axis tilt compensation for traversing and re-sectioning
- Survey-grade accuracy for each measurement
- Excellent measuring distance (300m at 90% albedo)

10-times Maximum Instantaneous Scan Speed Increase. In addition to field productivity gains for many applications, ScanStation
2’s bar-raising scan speed also lets users:

- Collect data in tighter time windows
- Reduce time spent in hazardous locations
- Provide project results even faster
- Collect even more complete as-built data
- “Squeeze in” additional service requests from clients

Actual field productivity achieved is dependent on many variables, such as the specific scan density and field-of-view selected for any given scan. ScanStation 2 shows off its pure speed the most in high-density scans, such as for building facades, plant as-builts, structural as-builts, and
forensic scene capture. Combined with the basic advantages of using this type of scanner for everyday topographic surveys, ScanStation 2
significantly expands the overall versatility of this scanner category.

Additional Advances Include Pointing to Pre-selected Coordinates Leica ScanStation 2 offers more advances than just a jump-step increase in scan speed. Another bar-raising addition is the ability to point the scanner’s visible green beam to a specific, pre-selected coordinate and dwell on the point. This allows visual location of points on surfaces, for
example to locate drill or attachment points for fabrication. This capability is an industry first for any type of laser scanner and is a direct result of the 50,000 points/second firing rate of the scanner’s
laser.

Leica ScanStation 2 also reduces the minimum point-to-point spacing that can be realized in any scan. The previous allowable minimum scan spacing was 1.2 mm; now users are free to space points less than 1 mm apart, for even higher-definition surveys of fine features such as architectural details or structural elements like bolt head geometry.

Lastly, ScanStation 2 also features a sleeker, lower profile housing design, 2.2 lbs (I kg) less weight, and a faster system boot-up, which
further increases field productivity.

“Leica ScanStation 2 not only represents a big advance in field productivity for pulsed scanners, but it sets the bar much higher in terms of what customers can expect from these types of systems. It reinforces the market’s view of Leica Geosystems as a true innovator and leader in High-Definition Surveying,” states Juergen Dold, Head of Leica Geosystems
Imaging and Scanning Business. “ScanStation 2 will provide clear benefits to users for a wide variety of as-built and topographic surveys.”

Leica Cyclone v5.8 is being announced simultaneously as companion software for operating ScanStation 2 and all other Leica Geosystems HDS scanners.

Pricing & Availability Leica ScanStation 2 will be available for shipment in the 2nd half of August. Pricing information is available via authorized Leica Geosystems representatives.
