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)

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)

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)

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)

GeoEye-1 Scheduled Launch in 2007

GIM Interviews Matthew O’Connell, President and CEO, GeoEye
On January 12th 2006 came the announcement that Orbimage had acquired Space Imaging. The newly formed company, GeoEye, flies the high-resolution Ikonos, Orbview-3 satellites and Orbview-2. In 2007 it will launch the very high-resolution GeoEye-1. Our interviewee Matthew O’Connell has 25 years experience in Mergers and Acquisitions. Some years ago he left Wall Street to work full-time for Orbimage, exploring the exploitation opportunities of acquiring Space Imaging. After the acquisition the brand name changed into GeoEye: why? We are in the business of providing GeoInformation and Geo-Intelligence. In a way, GeoEye is short for that. And our three satellites can... (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)

An Awakening in India: Interview with Bharat Lohani

Since the July 2014 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 the 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.   (By Wim van Wegen... (read more)

3rd International Conference on Cartography and GIS

The third "International Conference on Cartography and GIS" took place two and a half years after the second one, which was held in January 2008 in the Bulgarian winter resort Borovets. There were in fact two different conferences, since the cartography conference was preceded by a weekend of "Digital Earth", which was a conference in its own and only few participants attended both conferences.   The conference was thus turned into a summer conference, held at the Black Sea resort Nessebar, a town known for its beaches, and maybe even more for its rich history and culture. Nice summer weather seduced... (read more)

Towards All-in-one Photogrammetry

A Case Study of Dense Image Matching Using Oblique Imagery
Modern photogrammetric camera architectures provide high-resolution imagery in nadir and oblique views. This case study sets out to prove the potential of oblique imagery to deliver dense point clouds to be used for DEM, 3D city model and true orthophoto generation – an important step towards ‘all-in-one’ photogrammetry. 3D point clouds for DEM or orthophoto production are typically collected using airborne Lidar systems. The recent development of dense image matching methods provides an efficient alternative by deriving point clouds from imagery. Within this fully automated image processing pipeline, corresponding pixels between multiple images are determined. Each pixel represents a sight... (read more)

Geomatics and Surveying in Support of Land Administration

Implementing Tenure Security for All
Today’s geospatial technology means that land administration systems can increasingly be implemented for the benefit of all. It is now possible to conceive approaches to capturing the unrecorded geometry of boundaries for the billions of unrecognised land interests or spatial units. In addition, new approaches are becoming apparent for the maintenance of collected data. Examples from the field show that we’re well on the way to responding to the challenge. From a geomatics and geoscience perspective, many tools are already available to support development, but further steps are needed to operationalise them at scale. Read on for an article investigating a... (read more)
