New Wearable System Paves Way for Mobile Mapping for Mainstream Use in Surveying

NavVis, a pioneer of indoor spatial intelligence technology and enterprise solutions, has announced the launch of NavVis VLX, a wearable mapping system that captures high-quality data in even the most complex built environments such as construction sites, stairwells and small technical rooms. The all-in-one reality-capture capabilities of NavVis VLX include both survey-grade point clouds and high-resolution panoramas. The combination of high-quality data capture and a compact, economical design will transform the way AEC projects are captured with fast, efficient scanning for BIM and CAD applications, while also extending the scope of projects to new deliverables such as web-based digital twins....

Construction Economics is Fundamental in Responding to Coronavirus

How Improved Project and Cost Management of Construction is Critical to Recovering Economies
Global construction will be critical in countering the economic effects of coronavirus. Whilst most construction has been adversely affected in the short and medium term by closing sites, social distancing, material shortages and investment uncertainty, it will provide an important stimulus to the world economy if governments enable projects to proceed after the virus abates. Coupled with this, the crisis is providing a catalyst for change in the industry in terms of the greater adoption of technology, consideration of sustainability and social value impacts, and greater collaboration. Construction allows value creation – and the world will need this more than... (read more)

Accuracy Near, Far, Above or Under – How is FIG Working Week 2020 Contributing

The skills that engineering surveyors had to acquire in order to respond to the challenges of the construction world have made them capable, also, of fulfilling other challenges, several of which motivated by an awareness of the limitations of our planet. Engineering surveyors have learned that they need to push the equipment and techniques to its limits, while having recognized the necessity to integrate new techniques which can present more complete answers, without forgetting an important qualifier: accuracy. The instruments and methodologies have allowed for the surveying engineers to start working either very closely to the studied object, or, otherwise,... (read more)

Positioning the World for the Future

FIG Commission 5 focuses on meeting the highest level of accuracy for Positioning and Measurement. It provides the tools, techniques and procedures to educate and train surveying professionals everywhere. Appropriate methodology for data collection and processing are required to be successful in an era of global, integrated geospatial data. The body of work Commission 5 focuses on the science of measurement (instrumentation, methodology and guidelines). Its six WG’s focus on application of geodetic standards under ISO TC211 and TC176-SC6 to position within geometric and vertical reference frames using GNSS observations combined with multi-sensor systems to be as cost-effective as possible....

The Evolution of the Smart Surveyor

5 Trends Affecting Surveying, Bringing about the Next-generation Surveyor
These five trends currently affecting surveying are set to bring about the next-generation 'smart surveyor'. Surveyors are a versatile and flexible bunch. As the current COVID-19 situation has proven, this group, like others, has had to find new ways of operating. As illustrated by this article itself, which was originally planned as a presentation called 'Sensor Fusion for the Smart Surveyor' at the International Federation of Surveyors (FIG) Working Week 2020, adapting to a new platform for information sharing is becoming the new normal. In FIG Commission 5 – Positioning and Measurement and FIG Commission 6 – Engineering Surveys, the... (read more)

Smart Surveyors: Developments and Trends from the FIG Working Week 2020

Some of the challenges demanding innovative surveying approaches and technologies are rapid urban growth, smart energy, cleaner mobility, and ‘land rights for all’. Sensing technologies, spatial data processing methods, and related approaches are already available. However, the question is how to use and improve them to become future proof, smart surveyors? Only ten years left to achieve the SDGs for a sustainable future. How can smart surveying contribute? To answer these questions, the papers of the FIG proceedings were analysed by the author-team.In this short article, we present the main trends distilled and the papers we refer to, represent these...

Shedding Light on Earth

How Nighttime Lights Have Revolutionized the Way We Understand Our World
Images of Earth taken at night are revolutionizing our ability to measure and understand nearly every dimension related to human activity on Earth and allow us to get a glimpse into human/Earth interactions in near real time. The recent COVID-19 outbreak exemplifies how nighttime lights can help us understand the impacts of shocks on populations, economies and markets. Given the interdisciplinary nature of remote sensing-based socioeconomic research, a special issue of 'Remote Sensing' journal will bring together original and novel studies demonstrating innovative applications of nighttime lights-based analysis to broaden our understanding of human society and its further implications. Seeing... (read more)

Practise Your Lidar Skills Online!

Capturing ‘just’ aerial photographs is often not enough anymore. Users require 3D models to fit in their new developments or to correctly assess the suitability of a terrain. For this, two options are available: ‘classic’ photogrammetry from aerial photographs or Lidar measurements. The advantage of Lidar is that the point cloud is a direct output from the sensor and can thus allow the capture of more detail. Often, Lidar is used together with aerial photography to add texture and colour to the collected height data. In this e-learning module, you will learn about the challenges and possibilities of Lidar data and its combination... (read more)

GNSS Positioning at Centimetre Level for Dynamic Applications

Global Augmentation Services Support Driverless Vehicles
Mobile mapping, automated machine guidance and other dynamic applications employ global navigation satellite system (GNSS) receivers for positioning. To obtain centimetre-level positioning accuracies, augmentation services are needed to correct for atmospheric signal disturbances, clock errors and satellite orbit deviations. A major limitation of many solutions is that accuracy comes at the expense of long convergence times, which impedes the application in high-precision dynamic applications. This article outlines a solution based on global augmentation services. Precise positioning at the centimetre level cannot be achieved using GNSS signals alone. In addition, augmentation systems are needed. These consist of a network of base... (read more)
