Highlights of current issue are:
- Automated construction of runways with Leica Machine Guidance
“Unique“ is Zürich Airport's new tag-line. An apt choice, describing not only the impressive alpine panorama to which passengers are treated at landing and take-off, but also the remote-controlled technique now in use for constructing new taxiways – truly a world first. Just like the aircraft pilots taking off and landing only a short distance away, machine operator Beat Furrer has his concrete slip-former set to 3D automatic operation. Compared with previous runway construction methods, this technique puts costs on a controlled descent. There are no troublesome guide wires to be found on this site.
- “Geoinformation for all“ at ISPRS in Amsterdam
With over 2500 participants and numerous daily visitors, the ISPRS Congress 2000 in Amsterdam, became one of the largest meetings in the history of the International Society of Photogrammetry and Remote Sensing (ISPRS). The motto “Geoinformation for all“, puts a name to the task that is the most important for the experts of Photogrammetry and Remote Sensing in the new millennium. Even now, through various sensors, digital information flows into GIS-data bases making it possible to select and evaluate various information. More and more, different aspects of life are finding easier solutions based on geographical information systems.
- Big Belt and Öresund: “Terra firma“ has been reached
Europe is moving closer together: not only politically but also traffic wise. Old borders are being removed. Newest example: the 16km long bridge over the Öresund.
- Hongkong's bridges being monitored with GPS
Even if you now have to do without the excitement of approaching between high-rise buildings, landing at Hong Kong remains thrilling. Now passengers can see the Tsing-Ma bridge, a suspension bridge for road- and rail traffic and, at its construction time, the world's longest unsupported span section Not only was it constructed using Leica Geosystems surveying equipment, but recently it is being monitored with the latest Leica GPS systems.
- Measuring out a frozen drilling well
Tough times for a Leica TCA1700 series instrument: measuring boreholes in a man-made ice cavern at a tunnel construction site at Kingston-upon-Hull in north-west England.
- Vancouver's SkyTrain gets new tracks
There is some hard work going on in Vancouver, the Canadian Pacific metropolis. Two Leica TCA2003 total stations with automatic target seeking operate up to twenty hours daily along the route of a new stretch of SkyTrain track. “The beauty of the Leica Geosystems automatic target recognition instrument is that we can also work nights“, says Don Murray.
- High-rises out of cylinder
Stephansdom – Prater ferriswheel – Gasometer: these three man-made landmarks of Vienna have, for the past four decades, been prominently visible from afar. The UN City and the Millennium Tower have transported the Danube metropolis' skyline into modern times. The four gigantic Gasometers in the eastern section called Simmering, are being turned into living quarters and commercial centers. |
