Highlights of current issue are:
- Sydney is an exciting city for surveying experts, too
February 2000 marked the dress rehearsal, with 1250 athletes competing at the Australian Open Athletics Championships held in the newly-built Olympic stadium. Leica Geosystems total stations were deployed to measure jumping and throwing distances in Sydney’s new “Stadium Australia“. At the meeting, athletes were for the first time able to realistically assess sporting conditions in an arena with a seating capacity of 110,000. The stadium managers also made good use of this opportunity to test the efficiency of proceedings, and see how state-of-the-art measurement and transmission technologies could work together.
- The Matterhorn remains 4478 m high
The Matterhorn is precisely 4477.54 metres high – and remains at 4478 metres according to the maps. In the September 1999 re-survey featured in a recent “Reporter“, Italian geology professor Giorgio Poretti was the first to position a GPS surveying system on the peak, with LEICA GPS500s at reference points in the valleys on either side. All points were additionally measured using optical laser triangulation.
- The modern way to monitor reservoirs
The dams and water reservoirs in the German province of Baden-Württemberg are resurveyed every five years as part of an ongoing monitoring programme. One of the sites being checked is the Hornberg reservoir, located in the southern Black Forest on a mountain peak 1050 m above sea level. The reservoir feeds the Wehr hydroelectric power station, 630 metres further down and operated by Schluchseewerk AG. A study by the Geodetic Institute of the University of Karlsruhe set out to determine whether GPS measurements using Leica Geosystems’ new System 500 might be an economical and sufficiently accurate alternative to conventional terrestrial methods.
- Measurement and visualisation with Cyrax™
The history of modern surveying is in many ways the history of Leica Geosystems. Whenever new technologies made it possible to simplify the work of surveyors and engineers, the company came up with breakthrough solutions: the electro-optical tacheometer, infrared laser distance measurement and GPS are all witnesses to this pioneering role.
- Leica GPS selected for the Xian-Ankang Railway Project
China’s railway system is developing fast – and precision instruments are playing an increasingly important role throughout this major construction undertaking. The Leica GPS SR350 sets deployed on the Xian-Ankang Railway Project are an excellent example of the trend.
- GPS machine guidance system in open-cast lignite mining
Thanks to a new GPS-based machine guidance system supplied by Leica Geosystems, The North American Coal Corporation has achieved significant savings in annual operating costs at its San Miguel Lignite Mine in South Texas. |
