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)

Linking Space Technology and User Needs

GIM International interviews Carlo des Dorides, Executive Director, GSA
Space technology has a big influence on the transformation of the way we live, work and play. The core mission of the European Global Navigation Satellite Systems Agency (GSA) is to ensure that European Union citizens get the most out of Europe’s satellite navigation programmes. In this in-depth interview GSA’s executive director, Mr Carlo des Dorides, talks about Galileo, EGNOS, Copernicus, UAVs, location-based services and much more. The developments in the GNSS industry are continuing at a steady pace. Where do we stand now? As our GNSS Market Report shows, the global GNSS market remains dynamic. GNSS is used around...

Optimistic Outlook for Galileo

This month we bring you an extended interview with engineer Pedro Pedreira, executive director of the European Global Navigation Satellite System Supervisory Authority (GSA)since July 2005, the body charged with managing the development phase of the much-troubled European Satellite navigation system Galileo. Our wide-ranging discussion with Pedreira appears on these pages accompanied by detailed background information (boxed text). Despite the spiralling costs of Galileo, its anticipated economic benefits, in terms of revenue, employment and expanding markets, are many. Galileo is being funded by the EU taxpayer, so it is important that these benefits be realised. Please introduce yourself and tell... (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)

Solving Land Conflict in Africa

Cadastre Alone Not Enough
The governments of many African countries are currently investing in improving land administration with the aim of developing an efficient land market. A side objective is to reduce conflicts over land through implementation of a functioning land-registration and/or cadastral system. Experience teaches that additional preventative measures are required, such as conflict resolution, land management and psychotherapeutic approaches. Not even a perfect land market can prevent conflicts unless regulated by governing institutions. There are two types of institution: constitutive and regulative institutions. Constitutive institutions are needed to enable an economically efficient land market through land rights, land registration and rule of... (read more)

Geoinformation in Arable Farming

What’s Hot and What’s Not in Precision Agriculture
Agriculture enthusiastically absorbs geospatial technologies. Precision farming practices in particular benefit from location intelligence. The future in agriculture with geospatial applications is bright. Besides more efficiency on the farm, geospatial technologies also offer new business opportunities and new sustainability concepts. But the adoption of geospatial innovations is lagging behind expectations. So what’s hot and what’s not? This article examines the state of the art in geospatial technologies in agriculture and attempts to forecast the trends. By Tamme van der Wal and Henk Janssen, Wageningen University & Research (WUR), The Netherlands By far the most popular geomatics technology among farmers is... (read more)

Land Administration and Social Development

Enhancing Land Registration and Cadastre
Land and the way governments deal with it are of major importance for the development of any society. The authors present land administration systems as an instrument to support implementation of land policies and deliver the services required for security of tenure, markets, planning and taxation. In the Global Plan of Action for Sustainable Development adopt-ed by the Rio Conference 1992 (Agenda 21), global objectives of combating poverty, sustainable settlement, sustainable agriculture and forestry are directly relat-ed to the land issue. According to this plan, strengthening legal frameworks for land management and ownership is strongly recommended. The aim is to... (read more)

Good Governance, Good Geo-info

Essential Role for GI at all Levels
Where just two decades ago spatial data was mainly carried on paper maps, map and three-dimensional topographic data is now accessible via Google Earth. Where accurate positioning was once the professional pride of highly trained geodesists, we now see such services provided by GPS-based consumer products. This revolution in technological developments and demand for information implies the need for continuous upgrading of professionals: ‘lifelong learning’. Lifelong learning is relevant not only for the professionals concerned but also for their organisations. These are in a permanent state of flux in order to adjust to their continually changing envir-onment. This may flow... (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...

The Increasing Importance of Satellite-derived Bathymetry

Effective Surveying Tool For The Shallow Water Zone
Bathymetric data in the shallow water zone is of increasing importance to support various applications such as safety of navigation, reconnaissance surveys, coastal zone management or hydrodynamic modelling. A gap was identified between data demand, costs and the ability to map with ship and airborne sensors. This has led to the rise of a new tool to map shallow-water bathymetry using multispectral satellite image data, widely known as Satellite Derived Bathymetry (SDB). Read on for an article providing an overview of the SDB methods, showing how data can be integrated into survey campaigns and highlighting three use cases. (By Knut Hartmann,... (read more)
