Exceeding All Limits

Intergeo 2005 Düsseldorf, Germany – A Preview
This year’s Intergeo, to be held at the Exhibition Centre in Düsseldorf, Germany from 4th to 6th October, is expected to exceed all limits. With opening extended to three whole days and exhibition space to 10,000m2, it certainly looks as though big things are expected. And if organiser Hinte-Messe predictions prove correct, some 17,000 visitors and 1,500 conference delegates will attend. Nearly five hundred exhibitors have booked a stand at the trade-fair. It is not only in statistics limits are being pushed. The theme of ‘Exceeding limits’ reflects a wish to increase awareness of European expansion, globalisation and its effect... (read more)

Intergeo 2006 - Preview

10th - 12th October, Munich, Germany
‘Knowledge and Action for the Earth’ is the theme of Intergeo 2006, the annual geodesy and geo-information conference and trade-fair organised in association with the German Association of Surveying (DVW) and taking place from 10th to 12th October. Roaming as it does annually from one major city in Germany to another, Intergeo this year settles in Munich, world-renowned Bavarian capital of science, technology, arts and culture and, last but not least, the October Beer Festivals. Almost fifteen thousand visitors are expected to come together at the Neue Messe Convention Centre, the same number as attended the ESRI International User Conference... (read more)

Towards Cadastre 2034: Part II

International Experts Speak Out
Bennett and co-authors from the University of Melbourne, Australia, have described six design elements relating to the role and nature of future cadastres, presented at the FIG 2010 congress in Sydney and published in GIM International (July 2010); an inspiring starting point for further dialogue. To encourage discussion we invited leading experts and practitioners to send us their own views and future vision. We received no fewer than ten replies, half of which were printed in the September issue. Here are the remaining five.     Cadastre 2014 is an influential publication produced by a FIG Commission 7 working group... (read more)

GNSS Positioning

Status and Features
Nowadays, GNSS receivers have scores – and often hundreds – of channels, enabling them to track GPS, Glonass, Galileo and Compass signals simultaneously. The whole workflow from satellite tracking to calculating the coordinates of the position in a preferred reference system can be conducted automatically in real time. The price of GNSS receivers has dropped steadily since the first GPS receivers came onto the commercial market in 1982. In conjunction with the latest product survey results for GNSS receivers (available at www.geo‑matching.com), the author puts today’s GNSS status and features in perspective.

Laser Scanning Technology Challenged

Shortcomings in Spatial Documentation of Heritage Sites
In this month’s Insider’s View Prof. Heinz Rüther puts some critical points on the shortcomings of laser-scanning technology in the spatial documentation of heritage sites. We invited manufacturers of laser-scanning sensors and software to comment on his challenging observations. Nearly 70% of the companies responded (ten in total) and seven felt qualified to reply: Optech, Riegl, Leica Geosystems, 3rd Tech, Visual Learning Systems, TopoSys and I-SiTE 3D Laser Imaging. We thank all respondents for their time and effort. Critical observations made by Prof. Heinz Rüther include the following. (1) The processing time of laser-scan data can be up to ten... (read more)

Intergeo 2007 - Preview

Year after year Intergeo demonstrates how exceptionally flourishing is the geo(infor)matics business. Geo(infor)matics is all about improving human understanding of the earth, enabling management and staff in both public and private sectors to make better decisions and take optimal action. And Intergeo is all about the means of acquiring and processing the necessary geo-information. This year marks the thirteenth consecutive running of this major conference and trade-fair for geo­desy, geoinformation and land management. The venue shifts from year to year, always within the boundaries of Germany. Last year the event took place in three halls at the New Munich Trade... (read more)

3D is the New Normal in Switzerland

Mapless Topographic Products Are the Future
Switzerland is unique in that it is still the only country to have switched entirely to 3D for its national object-oriented topographic database. As users increasingly discover the advantages in terms of new workflows and services, nobody regrets leaving the 2D era behind. According to Swisstopo, the extra dimension creates no extra costs – only extra benefits. It took the Swiss Federal Office of Topography (Swisstopo) ten years to build an object-oriented topographic database in 3D, with the last objects having been completed in 2019. “Nothing is excluded now; everything you can think of is available in 3D. Even the... (read more)

Precise Point Positioning from Combined GNSS

Fugro Marinestar G4+ PPP-RTK Developments
Currently there are four global navigation satellite systems (GNSSs) available: GPS, Glonass, BeiDou and Galileo. The satellites of these systems are used for positioning, and the accuracy is greatly improved if precise satellite orbit, clock and uncalibrated phase delay (UPD) corrections are available when using the precise point positioning (PPP) technique. Fugro operates a worldwide network of reference stations capable of tracking GPS, Glonass, BeiDou and Galileo systems. This network is used to calculate precise satellite orbit and clock corrections of all four constellations in real time for maritime applications. The corrections are broadcast to users by eight geostationary L-band... (read more)

Towards Optimal 3D Point Clouds

Automation in 3D Mobile Laser Scanning
Motivated by the increasing need of rapid characterisation of environments in 3D, the authors have designed a robot system that automates the work of an operator of terrestrial laser scanners. The built system makes it possible to work without markers or targets, saving surveyors more than 75% of the time spent in the field. Another impulse for developing the platform was the demand for a remote inspection tool. The robot is capable of surveying remote sites or danger areas, such as plants, underground mines, tunnels, caves or channels. The availability of the robotic platform further enables the study of mobile... (read more)
