Leica Geosystems Announces Next Phases of 3D Laser Scanning Business

Heerbrugg, September 24, 2003 – Leica Geosystems (SWX: LGSN) today announced several developments in its emerging 3D laser scanning business (New Business Division). First, Leica Geosystems announced the concept of High-Definition Surveying™ (HDS™) as a new standard and refined description of what has often been referred to as “3D laser scanning.” This initiative recognizes both the basic differentiation of laser scanning versus discrete measurement methods and the technology’s maturation for surveyors and measurement professionals. Second, the Company announced its eagerly awaited, next-generation laser scanner, the Leica HDS3000, and software, Cyclone 5.0. These products will make laser scanning (i.e. High-Definition Surveying) more user-friendly and cost-effective for a broader range of as-built, detail and engineering surveys. Finally, acknowledging the complementary value of ultra-high-speed, phase-based laser scanners to Leica Geosystems’ versatile, time-of-flight scanners, the Company announced an OEM partnership with Zoller+Fröhlich (Wangen, Germany; www.zofre.de). Leica Geosystems will private-label Zoller+Fröhlich (Z&F) laser scanners as part of Leica Geosystems’ new “HDS product family”. Together these activities are expected to reinforce Leica Geosystems’ leadership position in this emerging market.

“We have chosen this new terminology, High-Definition Surveying™, partly in recognition of the increasing significance of this technology to surveying, engineering and other measurement professionals. Both TPS (Terrestrial Positioning Systems) and GPS are examples of how a technology solution can fundamentally improve the way work is done. High-Definition Surveying™ represents yet another major advance for these professionals,” states Erwin Frei, president of Leica Geosystems’ New Business (Cyra) division. “In addition to providing increased productivity for various applications, HDS™ also offers clients significant added value in accuracy, detail and completeness,” adds Frei.

Now Three Laser Scanning Systems Under the Leica Geosystems Name
By describing this technology as High-Definition Surveying, Leica Geosystems is stating that its new product generation is fully fit and friendly for surveying and measurement professionals. For example, the new flagship Leica HDS3000 time-of-flight scanner not only has the look and feel of a survey instrument, but it also supports many standard surveying procedures for instrument setup and operation. The Leica HDS3000 also features advanced capabilities that

Advances in Leica Geosystems’ ~~receives~~Industry ~~highest~~Standard ~~corporate~~Software Leica ~~sustainability~~Geosystems’ ~~rating~~HDS™ product family rounds out with the latest versions of Cyclone™ and CloudWorx™ software. They provide a full set of surveying and engineering tools for creating Leica-quality deliverables and managing large data sets with unparalleled ease and office efficiency. Cyclone 5.0, a major new release of the industry’s most popular point cloud processing software, enables a ten-fold increase in the size of high-definition data sets that can be easily managed. Like the HDS3000 laser scanner, Cyclone 5.0 also offers new features specifically for surveyors, such as “stationing” coordinates and alignment & offset notations. CloudWorx™ offers full CAD integration, making HDS™ data sets easily accessible to a wide array of professionals including architects, civil engineers, plant designers, etc.

Last year no company reached the “A” level in this rating of Center Info with a scale from A to E. With this “A” rating Leica Geosystems exceeds last year’s top 10 “B+” rating by the addition and improvement of the following elements: Code of Conduct, Export Policy, Community Affairs Department, Quality Policy, Guideline for Workplace Safety and Health Protection, information on internal staff commission, the practice of tracking and disclosing HR indicators, and the introduction of assessment of working conditions for contractors.

According to the research report issued by Centre Info, Leica Geosystems “shows a very satisfying commitment to its various stakeholders...is constantly aware of its customers’ needs...gives great importance to its employees...has improved its corporate governance rating...and cares strongly for the environment.” The report concludes with the statement: “Globally, the company demonstrates a very high level of environmental and social responsibility and rates among the most sustainable companies in Switzerland.”

Commenting on the new research report, Hans Hess, CEO of Leica Geosystems said: “We are extremely pleased that we could further improve on what we already considered to be an excellent rating. It is a tribute to the concern and dedication of all members of our company to an environmentally and socially sustainable development of Leica Geosystems.”

Also in the areas of strategic management and technology Leica Geosystems holds leading positions. For the strategy and realization of its business development concept, Leica Geosystems was awarded in 2002 with the “Merger & Acquisition Strategic Market Engineering Award”. In March 2003 Leica Geosystems was presented the “Swiss Technology Award” for its Trimo microoptics and blind navigation system.
