Bringing Geography into Everything

GIM International Interviews Ed Parsons
As Google’s geospatial technologist, Ed Parsons is responsible for evangelising Google’s mission to organise the world’s information using geography. GIM International caught up with this ‘man with a mission’ in Barcelona during one of his countless foreign trips. (By Wim van Wegen, GIM International) You’re the geospatial technologist at Google, responsible for evangelising Google’s mission to organise the world’s information using geography. Can you describe that mission? In many ways it’s quite a unique role since the number of people within Google that are really focused on outside the organisation is quite limited. A key aspect of the role is... (read more)

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)

Realizar un Catastro Actualizado en Colombia

Entrevista a José Agustín Wilches: Presidente de la Comisión de Geomática de la SCI
El Presidente de la Comisión Técnica Permanente de Geomática de la Sociedad Colombiana de Ingenieros (SCI), José Agustín Wilches, se mostró poco optimista ante la posibilidad de actualizar el catastro nacional colombiano a mediano plazo debido a la burocracia arraigada en el país. Adicionalmente a lo anterior, remarcó la amplia la brecha que tiene la nación, estimando que la causa del conflicto que se ha vivido por más de cincuenta años es justamente la tenencia de la tierra. Entonces, la seguridad jurídica de la tierra es prácticamente imposible que se logre mientras no se firme la paz y se llegue... (read more)

Bhoomi: An e-Conveyancing System for Karnataka State India

Storing Twenty Million Parcels
Bhoomi is one of the largest property-information databases in the world, containing land-administration information on twenty million parcels owned by 6.7 million farmers in 176 sub-districts of Karnataka State, India. As an e-Conveyancing system operating within a secure extranet, it provides public information on any agricultural land-parcel via its Kiosks. The author discusses the background, and implementation strategies and innovations, map issues, interoperability and lessons learnt. Bhoomi is built, operated and owned by the Revenue Department of Government of Karnataka, India. The National Informatics Centre, a Department of Government of India. The Government of India largely funded the project, with... (read more)

A Smarter Future for Geomatics

GIM International Interviews Thomas Kersten
Thomas Kersten is a professor of photogrammetry and laser scanning at HafenCity University Hamburg, Germany. He is currently also one of the ‘directors’ of the Oldenburger 3D-Tage, an annual conference on 3D optical measurement techniques, laser scanning and photogrammetry. GIM International spoke to him in February 2014 at the most recent edition of that event. Here, he talks about future technologies in the geomatics profession, data processing, archaeology as one of the many possible applications for geomatics, and HafenCity University’s philosophy. Which major developments do you foresee in terrestrial laser scanning (TLS) geodata acquisition technology in the next five years?... (read more)

An Awakening in India

GIM International Interviews Bharat Lohani
Since this issue of GIM International is dedicated to Lidar point clouds, it should come as no surprise that it contains an interview with a leading expert on this exciting aspect of the geomatics spectrum. Dr Bharat Lohani, who is leading the Lidar teaching and research group at the renowned Indian institute of IIT Kanpur and is a member of this magazine’s editorial board, was a logical candidate. In this interview he talks about India's role in the industry, his company Geokno, developments within Lidar technology and the geomatics programme at IIT Kanpur. You have a background in academia. What... (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)

FIG Standards Network

Early and Active Work by Professional Bodies
Standards are of great interest to surveyors, both as professionals and as business people. Early and active engagement with the process of standardisation by professional bodies such as the International Federation of Surveyors (FIG) should ensure more workable and timely standards that meet the needs of practitioners, their customers and the wider community. The format of telephone and bank-ing cards, quality management, environmental management, but also the international freight container; paper sizes and the universal system of measurement known as SI are all examples of standardisation. Standards provide economic benefits, bringing confidence that things will work and will fit together.... (read more)

Potential of Small Satellites

GIM Interviews Dr Rainer Sandau, Chairman, International Academyof Astronautics (IAA)
Small satellites for earth observation are an important ongoing development in space research. How can mapping and disaster management benefit from small-satellite systems? What is the potential and what the challenges? Are small satellites an inferior alternative for developing countries that cannot afford large satellites? This month’s interviewee, Dr Rainer Sandau, provides answers to these and other questions. What are mission, scope and organisational structure of IAA? IAA encourages international scientific co-operation through scientific symposia and meetings and through the work of six commissions dedicated respectively to Space Physical Sciences, Space Life Sciences, Space Technology and System Development, Space System...

The Power of Geography

At the end of the tumultuous eighteenth century the British government ordered its Board of Ordnance, the defence ministry of its day, to survey the country’s south coast. Today Ordnance Survey (OS) is a self-financing £100-million-a-year civilian organisation, still part of UK government but since 1999 having ‘Trading Fund’ status. Its workforce of around 1,500 people includes three hundred surveyors. How is OS coping with today’s technological challenges and social needs? What are the product trends, and what opportunities are offered by INSPIRE? Vanessa Lawrence, at the OS helm since September 2000, kindly answered these and other questions.<P> What are...
