Integrating the ‘Constructioneering’ Workflow Together

The How and Why of the Topcon and Bentley Partnership
Digitalisation and new technologies with the ability to revolutionise the geospatial industry are creating a new playing field for mapping and surveying professionals. This evolving landscape is also reshaping the industry, with new entrants gaining ground and established players seeking to collaborate and combine their specialist areas of expertise in order to offer a total solution. Wim van Wegen, content manager of ‘GIM International’, met with Ted Lamboo, senior vice president of strategic partners at Bentley Systems, and Ewout Korpershoek, executive vice president at Topcon Positioning Systems, at Bentley’s 2017 Year in Infrastructure Conference in Singapore. They discussed the partnership between... (read more)

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)

The Revolution of Drone-carried Sensors

GIM International interviews 3D Robotics
The world of professional unmanned aerial vehicles (UAVs or ‘drones’) is changing. It is a matter of ‘survival of the fittest’ in terms of the hardware aspect: UAV manufacturers. The interest is now visibly shifting towards payloads and software to capture, visualise and process the data; UAVs are the apparatus, but it’s the sensors and software that really count. GIM International decided to touch base with a company that serves as a good example of the current transformation, and spoke to Chris Anderson, CEO, and Daniel McKinnon, vice president, from 3D Robotics. Read the interview here. (By Wim van Wegen,... (read more)

Recent Advances in Geodata Acquisition Technologies

No Information without Data
Today’s geodata acquisition technologies combine microprocessors, computer power, solid state drives, complementary metal-oxide-semiconductor (CMOS) sensors, miniaturisation and many more developments. But demand is just as important as supply, and demand is rapidly increasing in our changing world. Read on for details of recent advances in geodata acquisition technologies. In today's world, we are seeing metropolises cluster to form megalopolises, climate change threatens humans, land and livestock in low-lying areas such as river deltas and valleys, and massively populated areas are prone to earthquakes and landslides. All of these factors are increasing the demand for geodata acquisition. This article starts with total stations, continues... (read more)

Technologies for the Future: A Lidar Overview

Building the Capability for High-density 3D Data
Point clouds can be captured by an ever-increasing number of means to understand the surrounding reality and detect critical developments. Diverse applications of 3D laser scanning or ‘Lidar’, which is a technology on a sky-rocketing path to be used for mapping and surveying, are changing the way we collect and refine topographic data. Which technologies and processes are building the capability for high-density 3D data? This article outlines the latest industry developments. National topographic databases store data refined from field measurements, imagery and laser scanning data at certain specifications and purposes, but lack the ability to adapt to ever-changing needs...

Need for New Players and Leaders to Enter the Land Sector

GIM International Interviews Dr Robin McLaren
Dr Robin McLaren is a widely known and recognised authority with more than 30 years of experience in the profession. Having developed GIS technology for a number of years, Robin set up his independent consulting company, Know Edge Ltd, in Edinburgh in 1986, providing GIS solutions for governmental and utilities clients across the United Kingdom. Following an introduction to international land administration and management during a UN-FAO mission to North Yemen in 1989, this became a major market for the company. 'GIM International' interviewed Robin to learn more about his involvement in many innovations and to hear his insightful opinions. Read... (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)

High-precision GNSS Receivers

The benefits and availability of new signals and systems
What will the new GNSS signals bring to the user of high-precision receivers? This article provides a brief overview of what users can expect from GNSS systems that are currently in the modernisation/development stage, looking at new signals and emerging techniques including coverage of GNSS developments such as GPS, Galileo, GLONASS and Compass/Beidou. In view of the planned timeframe, what we can do to improve the robustness of our receivers with a special focus on interference and the upcoming solar maximum? The use of high-precision GPS for surveying applications has increased dramatically over the last decade. GPS receivers can provide... (read more)

UAS-supported Agriculture: Still for Innovators

Greatest Potential on Small Farms
While unmanned aerial systems offer huge possibilities in modern farming, most of them lie in the future. These airborne vehicles currently mainly deliver images that are subsequently combined with other input in the farm-specific management system. In the future they will be able to contribute to land management and individual crop-product delivery based on real-time analysis. Another very promising segment for UAS-supported precision agriculture is water management. Precision agriculture is a relatively young concept, dating from around the turn of this century. The first products were focused on add-on guiding systems for tractors. These give a good return on investment,... (read more)
