Navigating the Future of the Geospatial and Geomatics Sectors

GIM International Interviews Dorota Grejner-Brzezinska
Dr Dorota Grejner-Brzezinska is the incoming president of the Institute of Navigation (ION). She also serves as president of the International Association of Geodesy (IAG) Commission 4, Positioning and Applications. GIM International held an in-depth conversation with Grejner-Brzezinska on the role of the ION, the latest developments and trends in GNSS survey solutions, and the future of GNSS. The Institute of Navigation (ION) serves a worldwide community including those interested in air, space, marine, land navigation, and position determination. How has the Institute evolved? The Institute of Navigation was founded in 1945 by a group of practising air navigators, originating... (read more)

Technologies for the Future: A Lidar Overview

Building the Capability for High-density 3D Data
Point clouds can be captured by an ever-increasing number of means to understand the surrounding reality and detect critical developments. Diverse applications of 3D laser scanning or ‘Lidar’, which is a technology on a sky-rocketing path to be used for mapping and surveying, are changing the way we collect and refine topographic data. Which technologies and processes are building the capability for high-density 3D data? This article outlines the latest industry developments. National topographic databases store data refined from field measurements, imagery and laser scanning data at certain specifications and purposes, but lack the ability to adapt to ever-changing needs...

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.

Capturing Geospatial Data from Vehicle Platforms

Jacobs’ Journey
Jacobs Geomatics provides support and consultancy to the company’s wider design and engineering services. In recent years Jacobs’ UK geomatics team has been involved in increasingly large infrastructure schemes, typically supporting preliminary and detailed design phases of projects. This requires advising on solutions and the subsequent provision of suitable geospatial data. As the projects have grown in scale and complexity, the company has increasingly sought to supplement traditional topographical survey capture techniques with rapid data techniques such as terrestrial laser scanning, aerial photography and Lidar. Over the past three to four years, Jacobs has also become increasingly involved in vehicle-mounted... (read more)

To Charge or Not to Charge

International Experts Speak Out
‘To Charge or Not to Charge: A Framework for Proper Funding,' was the title of a challenging article written by P.A.J. van Oort and A.K. Bregt of Wageningen University, Netherlands, and published in GIM International in August 2010. Based on an extensive review of the literature, and acknowledging that there is no one-size-fits-all solution, the authors developed a framework for selecting proper funding models. Free access is identified as the predominant model, but in some cases charging is seen as both viable and justifiable. The question of whether users should pay for geo-data produced by government and institutions has already... (read more)

A Brilliant Career

GIM International interviews Gottfried Konecny
Professor Gottfried Konecny, one of the most respected names in photogrammetry, shares some reflections on his work and profession. He worked in post-war Neumarkt as a teenage draughtsman, was chief surveyor on the 1965 Canadian Mount Kennedy expedition, mapped the lunar landing site at NASA, and has been involved in nearly all the European space mapping missions. And these are just some of Professor Gottfried Konecny’s extraordinary achievements. Today emeritus professor at the University of Hannover, he shares withGIM Internationalsome of the highlights of a career in photogrammetry that has spanned well over six decades.<P> Why did you choose a...

Alessandro Annoni Talks In Terms of Challenges

Impact of INSPIRE starting to become visible
Since its inception in 1997, INSPIRE has been one of the European Union's leading IT projects. The Directive mandates EU member states to issue all their environmental data in such a way that they can be discovered, viewed and accessed easily, by both public bodies and other interested parties, in order to help in decision-making and policymaking. Alessandro Annoni is head of the Spatial Data Infrastructures Unit of the Institute for Environment and Sustainability and, in this position, is responsible for technically guiding INSPIRE. GIM International talked to him to obtain an update on the status, the impact so far... (read more)

3D GIS in China

Chongqing Survey Institute Realised What Many Still Dream Of
Since 1998, the Chongqing Survey Institute (CSI) has been managing the 3D geoinformation database, including terrain, buildings, underground pipelines, geology and underground buildings, of the Chinese megapolis of 30 million people. For the commercial market, CSI’s 3D Mobile group focuses on combining the indoor and outdoor environment with e-commerce systems. Meanwhile, its BIM and GIS Integration group concentrates on three fields: geological survey, construction sector and municipal administration. Chongqing is a city of unique topographical and landscape features. It is built on mountains and partially surrounded by the Yangtze and Jialing rivers, making mapping the city a big challenge for...

Reviewing Aerial Survey in India

GIM International Interviews Mr K. Kalyanraman, NRSA, India
The Government of India on 19th May 2005 approved a radical New National Map Policy, ending decades of restrictive practise that had hampered geospatial development on the subcontinent (see Pinpoint August issue). This interview was conducted before announcement of partial lifting of restrictive practises. What level of expertise does NRSA possess in aerial survey? NRSA features a high-quality facility for carrying out aerial photography, Lidar and aeromagnetic surveys. Synthetic Aperture Radar (SAR) is being developed by the Department of Space and will be in operation in coming years. Well-established facilities for photo-processing, photogrammetric mapping, Lidar data processing and GPS ground... (read more)
