Kadaster: Ambitions and Goals

Leading Role for Key Registers
Programmes at European and national government level are signalling opportunities, setting policies and taking measures to capture the benefits of ICT. In tandem with societal demands, this will lead to government services via internet, key registers, web services and more. The author sketches the ambitions and goals of the Netherlands Cadastre (Kadaster) against a background of European policy, ICT developments and customer expectations. ICT offers many opportunities for improving the performance of government and business. Areas which may profit include education, safety, health care, international co-operation, economic efficiency (integrated value chains, business-process management, reduction in administrative overheads), prevention and detection...

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.

Laser-scanning and Heritage

Academic and Manufacturer Face Challenges
The March issue of GIM International carried the response of manufacturers of laser-scanning sensors and software to remarks made in the Insider’s View column on shortcomings of this technology in the spatial documentation of heritage sites. Based on his long-term experience in capturing heritage sites in Africa, Professor Rüther explains there is still ample room for development, a challenge for both academic and manufacturer. Judging from the responses to my original column, it appears some manufacturers interpreted my observations as rejection of laser scanning as a tool for heritage documentation. The opposite is true. Without doubt, laser scanning has high... (read more)

Earth Observation in Conflict Mitigation

Co-ordinated Mission
The conflicts in Darfur and Chad have led to excessive human-rights violations, including murder, rape and enforced displacement. Millions of civilians have had to leave their homes and hundreds of thousands have died as a result of attacks. The worst years of fighting were 2003 and 2004, but violence is on the increase again. International peacekeeping has not proved effective and access to humanitarian agencies is limited. A powerful tool in support of planning processes for international missions is earth observation (EO) via up-to-date satellite imagery.<P> In early summer 2008, the external relations directorate-general of the European Commission (DG RELEX)...

The Role of Surveyors in the Evolution of BIM

Building information modelling (BIM) is becoming more commonplace within construction sectors globally, combining technology with improved collaboration to better manage projects and give them the best chance of complying with time and budget constraints. However, the BIM life cycle and efforts to espouse it are almost futile if surveying is taken out of the equation or, more realistically, brought in too late. It can be good to have a structure that is successfully using BIM to be delivered on time and within budget, but if it or any of its components are in the wrong position, the consequences can be...

Road Resurfacing with Drones

Organisations that contract road-building projects typically compensate construction companies based in part on the excavation and transportation of the soil and the cost of the material. But traditional methods used to acquire this data can prove time-consuming, costly and unreliable. As a result, having an accurate assessment of the amount of soil used and the transported distance is essential in bidding, awarding and compensating a contract. (This article is brought to you by senseFly) To understand how to improve this process, Green Aero Tech, in consultation with the Saskatchewan Rural Municipalities of Piapot and Lipton, decided to investigate the efficacy...

Against the ‘How to Lie with Data’ Classification

New Task-oriented Methods for Designing Choropleth Maps
Choropleth maps are widely used for presenting population density, social index or other normalized statistical values related to spatial units. One of the ‘white spots’ on the research and development ‘map’ of cartography is that conventional methods for creating choropleth maps are data driven and may lose extreme values or small clusters of extreme values (hot spots) due to an unfavourable setting of class breaks. In this article, the author presents a new method and evaluation measures which enable better preservation of important spatial characteristics. The methods and software implementation result from the aChor project. The choropleth map is a... (read more)

Christ the Redeemer Reconstructed in 3D

UAV Deployed in Challenging Conditions to Reconstruct Iconic Statue
The famous statue of Christ the Redeemer in Rio de Janeiro has been reconstructed in 3D using a UAV. Challenging weather conditions and the sheer size of the monument meant that careful planning was required to complete the project and maintain safety. Thousands of pictures were captured around the statue and processed to create a large and accurate point cloud and a textured mesh. (By Lisa Chen and Sonja Betschart, Pix4D, and April Blaylock, Aeryon Labs) Fascinating images of the statue of Christ the Redeemer in Rio de Janeiro, Brazil, were seen around the world during last year’s FIFA World...
