Bringing Reality into the Information Space

Interview with Dr Bernd-Dietmar Becker, Chief Technology Strategist and Evangelist, FARO
FARO is known as a trusted source of high-precision 3D measurement, imaging and visualisation technology. In the surveying and mapping field, the company is particularly well known for its laser scanning solutions. On behalf of 'GIM International', Wim van Wegen recently met with Dr Bernd-Dietmar Becker, chief technology strategist and head of FARO Labs (the company’s research and innovation department), to discuss what we can expect from laser scanning and its role as key reality capturing technology in the years ahead. You recently announced that you have divided your business into six vertical sales and product management business units. What is... (read more)

Capturing, Modelling and Building the Reality

Interview with Aidan Mercer, Bentley Systems
Bentley Systems held its latest annual Year in Infrastructure Conference in London, UK. The event proved to be an excellent opportunity to take a look behind the scenes at Bentley, a leading provider of software solutions for advancing infrastructure. 'GIM International' talked with Aidan Mercer, global industry marketing director for utilities and government. In this in-depth discussion, he zooms in on the role the company plays in advancing the world’s infrastructure and how geomatics is a key element of many of Bentley’s applications. (By Wim van Wegen, content manager, GIM International) We’re hearing a lot about reality modelling at Bentley’s Year... (read more)

Thomas Kersten Foresees a Smarter Future for Geomatics

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 earlier this year 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. (By Wim van Wegen and Mark Pronk) Which major developments do you foresee in terrestrial laser scanning (TLS) geodata... (read more)

Towards Optimal 3D Point Clouds

Automation in 3D Mobile Laser Scanning
Motivated by the increasing need of rapid characterisation of environments in 3D, the authors have designed a robot system that automates the work of an operator of terrestrial laser scanners. The built system makes it possible to work without markers or targets, saving surveyors more than 75% of the time spent in the field. Another impulse for developing the platform was the demand for a remote inspection tool. The robot is capable of surveying remote sites or danger areas, such as plants, underground mines, tunnels, caves or channels. The availability of the robotic platform further enables the study of mobile... (read more)

Harmonising UAS Regulations and Standards

GIM interviews Peter van Blyenburgh, president of UVS International
Many people dream of making a living out of remotely piloted aircraft systems (RPASs), but so far a lack of clear rules and regulations has stood in the way of that dream. However, there is a glimmer of hope on the horizon – especially in Europe – and best practices will spread across the world like an ink blot, according to Peter van Blyenburgh, president of UVS International. His independence from individual companies or governments makes him notoriously frank and he is an outspoken ambassador for the sector on all five continents. Your main concern over the past decade has... (read more)

Recent Developments in Airborne Lidar

Multispectral Laser Scanning, Single-photon Lidar, Hybrid Sensors and UAVs
The arrival of airborne Lidar, also referred to as airborne laser scanning (ALS), has revolutionized area-wide 3D data acquisition of topography, bathymetry, vegetation, buildings and infrastructure. This article presents an overview of the progress made since then in both sensor and aircraft technology. On top of that, it highlights how the ongoing miniaturization has recently enabled the application of Lidar on unmanned aerial vehicles (UAV), resulting in ultra-high-resolution 3D point clouds with centimetre precision. From Single to Multiple Pulses in the Air Current trends include a steady increase of the measurement rate, achievements in full waveform processing, the spread of... (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)

Precise Point Positioning from Combined GNSS

Fugro Marinestar G4+ PPP-RTK Developments
Currently there are four global navigation satellite systems (GNSSs) available: GPS, Glonass, BeiDou and Galileo. The satellites of these systems are used for positioning, and the accuracy is greatly improved if precise satellite orbit, clock and uncalibrated phase delay (UPD) corrections are available when using the precise point positioning (PPP) technique. Fugro operates a worldwide network of reference stations capable of tracking GPS, Glonass, BeiDou and Galileo systems. This network is used to calculate precise satellite orbit and clock corrections of all four constellations in real time for maritime applications. The corrections are broadcast to users by eight geostationary L-band... (read more)

Indoor Positioning

Technologies, Features and Prospects
Outdoor positioning and navigation techniques using GNSS have been well explored and are now a vital part of daily life all over the planet. Since GNSS was initially designed to support the military during open-air combat, there was no need for the signals to be able to pass through walls and roofs. Indoor positioning therefore requires the alternatives to GNSS. How can geomatics contribute to the deployment of indoor positioning solutions? In aiming to find answers to that question, this article also examines current technologies and the various types of applications they originate from. An indoor positioning system is a... (read more)
