High-precision GNSS Receivers

The benefits and availability of new signals and systems
What will the new GNSS signals bring to the user of high-precision receivers? This article provides a brief overview of what users can expect from GNSS systems that are currently in the modernisation/development stage, looking at new signals and emerging techniques including coverage of GNSS developments such as GPS, Galileo, GLONASS and Compass/Beidou. In view of the planned timeframe, what we can do to improve the robustness of our receivers with a special focus on interference and the upcoming solar maximum? The use of high-precision GPS for surveying applications has increased dramatically over the last decade. GPS receivers can provide... (read more)

Difference between Theory and Practice

GIM Interviews Dr Vladimir Gershenzon, General Director, ScanEx
The third international conference on "Earth from Space" took place from 4th to 6th December in Moscow, Russia, with the theme "Most Effective Solutions". This meeting, accompanied by a small exhibition, aims to provide a forum for the exchange of experience in the practical use of satellite imagery for a broad spectrum of applications. ScanEx, headed by Dr Vladimir Gershenzon, is the main inspiration behind the conference. We interviewed him there.<P> When, why and how was ScanEx established, and what are your main products and services?   After my graduation in 1980 I worked for several years at different institutes...

High-level Political Support Needed

GSDI and Land Administration within Europe
Administrative reform within Europe has had a tremendous impact on land administration all over the continent. Geo-Spatial Data Infrastructures (GSDI) may bring further improvements. The authors review land policy, land administration and the role of land information within society, and call for high-level political moves towards information sharing. Examples of administrative reforms within Europe are restoration of the primacy of politics, reduction in ministerial tasking to core business, and improving the output of public institutions by distance steering, decentralisation and de-concentration of institutions. Other methods of improving output include quality assurance programmes, special service projects, restoring democracy and reestablishment of... (read more)

Mapping an Oil Pipeline

DEMs and Ortho-imagery for Colombia from Dual-band Side-looking Radar
Adverse weather and terrain conditions meant the Cano-Limon oil pipeline in Colombia had never been accurately mapped until orthorectified images and digital elevation models covering an area of 94,000km2 were created using airborne dual-band interferometric IFSAR simultaneously acquired X and P-band data. The authors report on main aspects of the project. The Cano-Limon oil pipeline extends nearly 780km from the Cano-Limon oilfield in Colombia’s Arauca region along the north-western border with Venezuela to a port in Covenas. When fully operational the pipeline can carry up to 20% of Colombian petroleum production, a major source of national revenue. In collaboration with... (read more)

BIM: A New Model for Surveyors

Important Opportunities and Challenges for Surveyors
Building information modelling (BIM) is one of the most intriguing opportunities for surveyors to come along in years. This model-based approach combines technologies and processes to support the efficient creation and use of information for building construction and operations. Because of its strong ties to spatial information, BIM offers a familiar landscape and rich possibilities for surveyors and other geospatial professionals, according to Ron Bisio, vice president of Trimble Geospatial. The opportunities stem from the growing acceptance of BIM within the surveyor’s traditional client base of engineers, architects and property owners. By gaining an understanding of the key concepts of... (read more)

Solving Societal Problems with Smart Cities

Interview with Martin Powell, Head of Urban Development, Siemens
The world population is growing rapidly, putting urban planning under increasing pressure. Cities are facing challenges such as how to improve the environment and how to reduce the impact of congestion. The smart city concept seems to offer a solution. Reflecting the fact that smart cities are built on geospatial foundations, Intergeo – the world’s largest annual trade show for the geomatics industry – chose smart city as one of its key themes. To gain insights from an urban planning insider, 'GIM International' interviewed Martin Powell, head of urban development at Siemens. (By Wim van Wegen, GIM International) ‘Smart city’... (read more)

Enormously Exciting Future in Geomatics

GIM International Interviews Hans Hess, exiting CEO, Leica Geosystems
Autumn 2005 brings at least two major changes to Leica Geosystems. The company has been taken over; in mid-October Sweden-based Hexagon formally took ownership. In addition, Hans Hess has left his post as CEO of Leica Geosystems, succeeded as of November 1st by Hexagon CEO Ola Rollén. We interviewed Hans Hess at Intergeo 2005. Leica Takeover On 27th October 2005 Leica Geosystems announced that following the takeover by Hexagon the Board had appointed Ola Rollén, CEO of Hexagon, as president of Leica Geosystems with effect from 1st November 2005. The current Board of Directors will step down at a specially... (read more)

Automated Map Generalisation

Meeting Today's Information Demands
Nowadays spatial information is much more often displayed on digital devices than on a paper map. Within digital environments, users have high expectations regarding up-to-date information and consistent data when zooming in and out. The recent progress in automated map generalisation offers the potential to meet those high expectations. ‘Generalisation’ of geoinformation is the extraction of less-detailed data from highly detailed data to fit a specific purpose. Less-detailed data is more suitable for displaying geoinformation at small scales and for obtaining overview-like visualisations of a particular area. Interactive generalisation is time- and labour-intensive: it can take years to generalise a... (read more)
