GNSS Receivers – Evolution or Revolution?

Past, Present and Future of Positioning
Satellite surveying… are there any industry professionals out there not using it on (almost) a daily basis? Over the last 30 years, GNSS has become the main positioning instrument for most applications, writes Huibert-Jan Lekkerkerk. Of course, there are still some exceptions where correct relative positioning is needed and dedicated optical systems such as a total station or level instrument are used, but even these are often set up over control points determined using GNSS techniques. This article investigates the developments in GNSS over the last decade and attempts to predict the future. Around a decade ago, a review of... (read more)

How Drones are Future-proofing the Construction Industry

Flying High for More Data and Detailed Insights
Drones are enabling construction professionals to access more data and detailed insights to create the reliable, sophisticated design models that are needed to stay ahead of the competition. It’s no secret that ensuring construction projects remain on time and in budget is crucially important for all stakeholders and demand continues to grow for faster, more readily available and up-to-date information. The goal? To optimise operational productivity and efficiency during projects and help the industry evolve and grow. Indeed, reports claim that if construction productivity were to catch up with the global economy, the sector’s value would increase by an estimated... (read more)

The Expanding Use of UAVs in Construction

Flying to Build a Better Product
It is an exciting time for geospatial professionals. The data that can now be obtained using unmanned aerial vehicles (UAVs, or drones) opens up previously impossible opportunities in many different industries. At the forefront of these is the construction industry. As a geospatial engineer working for a general contractor, Michael Schwind is always looking for new ways to utilize UAVs and the resulting data to improve efficiency and communication, and to detect and prevent costly – or even deadly – mistakes before they occur. In this article, he discusses some of the obvious and not-so-obvious ways that Fulton Construction, a... (read more)

The Rising Demand for Total Stations and Terrestrial Laser Scanners

How the Booming Construction Business Boosts the Geospatial Industry
Increasing investments in large infrastructure and construction projects, and the rising role of building information modelling (BIM), are expected to drive the market for geospatial equipment. BIM’s close connection with spatial information makes it a familiar landscape and offers rich possibilities for surveyors and other geospatial professionals. Geomares – publisher of 'GIM International' and 'Geo-matching' – has analysed the user data and behaviour of thousands of members of the global geospatial community. It is interesting to see how the market of ‘traditional survey equipment’ such as total stations and terrestrial laser scanners is responding to the growing construction market and... (read more)

Technical Advances Bring Digital Twin of Underground Infrastructure Closer

Mapping the underground is one of the major challenges in creating an infrastructure map at the municipal, regional, and national level, which is a key foundation for a national digital twin. Recent technical developments include: the ability to collect data at highway speeds that can be used to create a 3D model of underground infrastructure, software that can extract relevant 3D underground information from consumer digital photography, and video capture. Meanwhile, novel ways to share information about underground infrastructure, and progress on standards for sharing information about the subsurface are making mapping the underground increasingly feasible. The uncertainty in the... (read more)

Enhancing Virtual Singapore with BIM Data

The 'Virtual Singapore' platform will include a software and data standards component to automate the enhancement of information from source BIM data models. Drawing on leading science and design principles, Singapore combines characteristics from both the natural and man-made environments in a way that creates a sense of harmony and balance, also giving the city its unique feel and identity. This is best observed from any number of skyline terrace bars in downtown Singapore, but especially during the sunset hours – the transition between day and night as light reflects across the Marina Bay, and all the shiny edges and...

The 123 of AEC: Renewing the Architecture, Engineering and Construction Industry with Satellite Imagery

A reoccurring sustainable issue faced by the Architecture, Engineering and Construction (AEC) industry is that of green buildings. The global market for green construction is projected to reach $364.6 billion USD by 2022. The demand for this kind of minimally invasive construction design will not only increase over the next 25 years, but is also set to significantly alter the industry. Combined with population growth, a challenge now exists for AEC professionals to creative innovative designs that are both economical and sustainable long term. Incorporating Very High Resolution (VHR) optical satellite imagery into the planning and development stages of any... (read more)

Changing the Game with Mixed Reality for Construction Planning and Operations

Construction teams are constantly looking for ways to improve safety and productivity on-site. The immersive visualization of Bentley’s SYNCHRO XR application with HoloLens 2 provides a quick and easy way to evaluate the project plan against the actual constraints of a job site. Bentley Systems recently showcased the new capabilities of Microsoft’s HoloLens 2 with a preview application built into the SYNCHRO digital construction environment. Using head-mounted devices, HoloLens 2 allows you to see your surroundings while the holograms also appear to be part of your physical job site. More intuitive and user-friendly The interaction patterns for HoloLens 2 have... (read more)

Lidar Point Cloud Segmentation

A Novel Framework for Processing Terrestrial Lidar Data
Terrestrial Lidar data has great potential to produce measurements for as-built building information modelling (BIM). Unfortunately, processing hundreds of millions of points, often contaminated by substantial noise, can be tedious and time-consuming. Normal variation analysis (Norvana) segmentation is an automatic method that can segment large terrestrial Lidar point clouds containing hundreds of millions of points within minutes. Thanks to the high speed, point density and accuracy of modern terrestrial laser scanning (TLS), as-built BIM can be conducted with a high level of detail. But TLS captures not only useful geometric information but also unwanted objects, such as people, animals or... (read more)

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)
