Unlike ordinary glaciers, rock glaciers are not extensive bodies of ice but mixtures of rock debris and ice that flow down valleys at speeds of 0.1 to 1 m (0.3 – 3.3 ft) per year. They are typical in alpine or high mountain permafrost regions and direct conclusions about climate change can be drawn from their movement. Investigating the movement dynamics of rock glaciers presents a great challenge to all the various earth science disciplines involved. Students at the University of Applied Sciences Northwestern Switzerland (FHNW) have taken on this challenge with the help of a Leica HDS4400 long-range scanner. more

The Cambridge doctoral students Till Wagner and Nick Toberg spent a month last summer surveying the dimensions and properties of the thin floating ice floes in the wilds of the Arctic between Svalbard and Greenland aboard the Greenpeace ship Arctic Sunrise.
The aim of the expedition was to collect data that would provide firsthand insights into local ice conditions in September, the period of most rapid melt. The gathered data will also be helpful to remote sensing scientists to validate satellite measurements and to global climate modelers to provide more accurate input for their simulations. To ensure success, they needed just the right total station to tie in snowdepth readings, aerial imagery, and drilling sites with their 3D laser scanner data, and to produce low resolution surveys of the ice topography. more

Ten years ago, RTK surveys typically involved two GPS receivers (a base and a rover), a lot of batteries and cables, two radios, a tripod, a pole, and a backpack to carry it all. Today users can choose between a GPS or a GNSS receiver, and a radio or a mobile phone, and it all fits on the pole. With the establishment of RTK networks, they can also choose to work with an RTK rover within these networks instead of setting up their own base-station. Leica Geosystems SmartNet gives users easy access to precise Network RTK data, where they experience the best availability, reliability, and traceability using internationally recognized standards, combined with flexible and affordable subscription options that meet the needs of the local market. more

On three closely linked interdisciplinary projects, two of which are within the remit of the Competence Center Environment and Sustainability of the ETH Domain (CCES), the Institute of Geodesy and Photogrammetry (IGP) at the Swiss Federal Institute of Technology Zurich (ETH) opted for the Leica GRX1200 reference station receiver. The scope of the projects extends from research into tectonics, the movements of block glaciers right up to the determination of atmospheric water vapour content. The common denominators are sustainable studies in the fields of energy and environmental catastrophes as well as the Leica ATHENA Program for Higher-Education and Non-profit Organizations. more

The town of Staufen in the Black Forest has literally been torn apart: following failed geothermal borehole drilling, the ground on which the town and its 7,800 inhabitants stand has risen by up to 40 cm (15.7 in) in the last three years. This has had serious consequences for some of the houses in this historically listed town, some of which have cracks running through them that are up to 10 cm (3.9 in) wide. The town council commissioned surveying engineers Weber to set up a geodetic deformation network to monitor the continuing rise of ground levels. more

Lost in the vastness of the South Pacific, a unique island rises out of the ocean. The inhabitants call it “Rapa Nui”. The European “discoverer” who sighted the island lying thousands of kilometers away from the nearest continent, or even another island, on Easter Sunday in the year 1722, several hundred years after the Polynesians, rather unimaginatively named it Easter Island. Milosch Dryjanski journeyed there with his team of speleologists and three Leica DISTO™ laser distance meters to unlock some of Easter Island's subterranean secrets. more

(Reporter 50, April 2004) For the first time ever, a Leica GPS system records
movements around Mt. Everest every 30 seconds...
Mountain climbers and scientists aren't the only
things that move around on the world's highest
mountain; in fact, Mt. Everest and the entire
Himalayan region is constantly transforming itself. In
order to capture the positions of people and nature
as well record their movements, a permanent,
solar-powered Leica GPS 530 surveying station was
installed in 2003. It is located on the Nepalese side of
the mountain, near the glass research pyramid that
was set up more than a decade ago by the Italian
research team "Ev-K2-CNR". more

(Reporter 48, Jan 2003) Nowhere is volcanism more impressive and varied than on the largest volcanic island of the earth – Iceland. During the last decade the European Space Agency (ESA) has supported a number of disaster monitoring research projects utilizing the radar satellites ERS-1
and ERS-2. Following the recent launch on 1 March 2002 of the ENVISAT – Europe’s newest polar-orbiting scientific satellite – it is envisaged
that this continuing research will be greatly improved. more

At 6,962 Metres on Aconcagua in January 2001: Climber Gianpetro Verza has just mounted the terrestrial reflector signal to enable the classical terrestrial survey with tacheometres from the valley, and he has fixed on the top the Leica GPS 530 antenna. This configuration allowed at the same time measurement in both technologies with high accuracy. Verza has put the Leica GPS530 terminal, the same equipment as used on Kilimanjaro, before him on the summit. more

Tectonically, Central and South America are extremely active zones. The Nazca, Cocos, Caribbean and South American plates all influence each other with their movements. This area has for a long time been the target of geological research into the complicated patterns of change. The Leica GPS System 300 has contributed considerably to the results which have been attained. more
