Digital Oblique Aerial Cameras (2)

A Survey of Features and Systems
In recent years, aerial photogrammetry has increasingly been using camera systems which capture nadir and oblique images at the same time. The number of oblique systems on offer in the marketplace for airborne geodata collection is growing steadily – a strong indicator that the technology is rapidly maturing. In this follow-up article, the author highlights oblique systems from Digicam, Dimac, Icaros, VisionMap and Wehrli. (By Mathias Lemmens, Senior Editor of GIM International, The Netherlands) The previous article on digital oblique aerial camera provided a general introduction to oblique aerial imagery and the diverse camera configurations which allow oblique image capture....

ITC and UNU

Developments in Geomatics Education (8)
In 2005 ITC (International Institute for Geo-Information Science and Earth Observation) Enschede, the Netherlands, became an associated institution of the United Nations University (UNU) in a co-operation focused on disaster management and land administration. Described here are the role of UNU and the ITC contribution. For 32 years now the United Nations University (UNU) has been delivering research and capacity building to resolve global problems of concern to the United Nations (UN), its peoples and member states. UNU, an autonomous UN organ with as rector a UN under-secretary, fosters intellectual co-operation among scholars, scientists and practitioners, especially in the developing... (read more)

Lidar, Imagery and InSAR for Digital Forestry

GIM International interviews Benoît St-Onge
Benoît St-Onge is a professor at the University of Quebec in Montreal, Canada. He works at the Department of Geography with a major research interest in 3D remote sensing for forest analysis. 'GIM International' recently interviewed Professor St-Onge to gain a better understanding of the challenges and innovations in this field. (By Martin Kodde, contributing editor, GIM International) In your research work, you have a clear focus on the use of Lidar and photogrammetry for analysis of vegetation, forests, etc. How did your interest in vegetation develop? When I chose to specialise in remote sensing at master level in the 1980s,... (read more)

Leica Geosystems, HDS

Fifth User Conference and HQ, San Ramon, USA
Terrestrial laser scanning combines a high level of detail with surveying accuracy for the creation of 3D-models of virtually any object. The technology literally opens up new dimensions and so attracts widespread attention. It is in the interest of manufacturers to bring these people together for cross-fertilisation of ideas, so to drive the makers on towards problem solving and new survey solutions. Leica Geosystems HDS held the fifth such get-together in California from 22nd to 24th October 2007.<P> Arriving tired and tense after an intercontinental flight, the journey from San Francisco International Airport to San Ramon feels fraught. After a... (read more)

The Search for the Economic Value of 3D Geoinformation

Adding a Third Dimension to the Mapping Agencies’ Dominant Data Environment
In 2017, 11 European public mapping agencies (PMAs) financed a EuroSDR project to explore the economic value of 3D geoinformation. They gained from being able to share knowledge with one another about the findings and their concerns. For the investigated cases, the cost-benefit ratio was found to be about 1:3. Since the calculated financial benefits were rather circumstantial, however, the academics involved in the project complemented the study with a scientific article in which they attempt to provide more nuance by focusing on the broader public value. They conclude that, in general, the use of 3D geoinformation is increasingly profitable.... (read more)

Infrastructure Group Benefits from Drone Technology in Smart Motorways Project

The international infrastructure group Balfour Beatty is reaping the rewards of using drones on major construction projects, including work on a multi-million-pound 'Smart Motorway' upgrade in the Midlands region of the UK with support from UAV specialist Heliguy. The group is utilizing unmanned aerial vehicles (UAVs or 'drones'), including the recently released DJI Phantom 4 RTK, to enhance safety, increase efficiency, gather data faster, improve asset productivity and gain high-accuracy results. The UAVs are being used for quicker stockpile measurements, informative aerial progress reports and accessing hard-to-reach areas. Balfour Beatty has turned to drone expert Heliguy as its preferred supplier,... (read more)

Land Administration Census

A Plea for a Bottom-up, Brute-force Solution
The battle against poverty in developing countries has always been associated with the issue of land. Since the turn of the millennium, the focus has been on facilitating the official registration of land rights by the poor and the vulnerable. Many countries in sub-Saharan Africa still lack a well-functioning land administration system, notwithstanding many dedicated aid programmes. Such programmes were designed by Western institutions and often copied Western land administration architectures. In this article, the author advocates a bottom-up approach using census-taking as a paradigm. First the capabilities of advanced technologies are identified, then the way aid is brought to...

2D and 3D Enrichment of Panoramas

Visualisation of Topographical Features Improves Functionality
The use of panoramic images has become widespread in many governmental agencies and companies, especially in the last couple of years. It is possible to integrate 2D spatial features (e.g. building outlines, parcels, utilities etc.) with panoramic images to enable the proper visualisation of topographical features in a 3D environment. Verbree et al. (2004) have shown the advantages of augmenting underground conduit pipes and cables into panoramic images, thus allowing better visualisation of otherwise invisible features. The geometric augmentation of 2D features into panoramic images enables users to identify, query or analyse any geographically related information in a 3D environment.... (read more)
