Highlights of current issue are:
- Lighthouse relocation
It’s not really the application developers had in mind when they introduced the powerful, speedy and accurate Leica one-man robotic survey system – nor did they envision that one man might have reason to operate two at the same time. But that’s exactly what happened during three surprising weeks this summer on the North Carolina shores during the historic Cape Hatteras Lighthouse relocation.
- Modern cadastral system in Budapest
The land registration sector is a key component of our free market economy. We recognize the variety in land administrations all over the world but one thing is common, the need of a modern, well functioning land administration system which is one of the essential pillars of the free market economy and the land market. The demands for land registration activities and data is increasing year by year and a growth towards related applications like Geographic Information Systems (GIS) is one of the most important changes over the last few years.
- Bridge monitoring in Shanghai
With a span of 620m, Yang-Pu bridge is not only one of the longest suspension bridges in the world, but also one of the busiest. Stability and reliability of such a bridge is very important, and regular checks are necessary to provide the highest security. Surveying technology has evolved during the last few years to introduce new systems to improve the accuracy of measurements and greatly reduce the time needed to perform such tasks. By using automated Leica total stations, able to find the targets automatically, combined with deformation measurement software, results can be viewed directly on site.
- Reconstruction of the interior of an aircraft
Using terrestrial photogrammetry for creating a photorealistic CAD model of the aircraft's interior the Transportation Safety Board (TSB) of Canada contacted Leica Geosystems to check whether Leica's coaxial red laser EDM could serve as a part of a proof-of-concept on a MD-11 aircraft. Working with the new Leica TCRA1103 Total Station the team members were impressed by the ease and accuracy with which the data were measured, and agreed that the volume of data could have been collected no other way.
- Berlin’s renaissance
The former border between east and west is now the world’s largest urban construction site, with spectacular projects taking shape everywhere. Dense networks of underground road, rail and metro tunnels and a welter of high-rise developments present big challenges to survey and construction specialists. A local GPS network monitors the giant construction sites at the Potsdamer Platz, the government quarter, and the new main station at Spreebogen with millimetre accuracy. The survey network, covering 16 km2 of Berlin construction sites, was staked out in the early 1990s using Leica systems.
- Re-measurement of Kilimandjaro
Kilimanjaro lies in the north of Tanzania, about 3° south of the equator. This extinct volcano towers about 5000m above the surrounding plains (themselves about 800m to 1000m above sea level), has a base of approximately 60km x 40km, and is the world’s largest free-standing mountain. With fascinating climatic zones ranging from tropical forests to glaciated summit regions, and wonderful views over the vast plains of East Africa, Kilimanjaro attracts many tourists from all over the world particularly as the standard ascent requires no special mountaineering skills.
- Highest building of Saudi Arabia
What is recognized today as the highest building of Saudi Arabia started in April 1997. Taking over responsibility for all surveying work of the Al-Faisaliah Tower in Riyadh we had to lay out the main points for the location of the building and its main axis. Using a Leica TC1800L total station with EGL guidance we achieved an accuracy of ±3mm for the traverse. To control the core wall verticality we set out 40cm permanent offset points at each corner of every wall at the base of the tower.
- From Geodesy to Physiology
Would tri-axial accelerometers and indirect calorimetry bring new perspectives to Leica receiver GPS System 500 ? We believe so, since the combined utilization of such devices is of major interest in the world of applied physiology. |
