Indoor Mapping: We Have Only Seen the Beginning

Indoor mapping is often associated with the rise in location-based services, but over the past few years there has been a growing demand for indoor mapping for a much wider range of use cases. In fact, it is fair to say that the evolution of indoor mapping has only just got started. Read on to find out why. The biggest trend is that mobile indoor mapping is taking on more of the work traditionally performed by static laser scanners. Some of the earliest adopters of simultaneous localisation and mapping (SLAM) technology were surveyors and engineers. Faced with growing demand for... (read more)

Six Facts You Need to Know about 3D Reality Capture

Rapid changes in technology and computing power are affecting almost every aspect of our lives – from democratization and information access to communication and how we visualize the world around us. As technology becomes smaller, more affordable and more automated, 3D reality capture is becoming more accessible to a wide range of applications and everyday users, not just specialists. Whether you are a savvy user or new to 3D reality capture, Jürgen Mayer, president of Hexagon Geosystems’ Reality Capture Division, explores six facts in this interview. 3D reality capture solutions form the bridge to transform the real world into mirrored...

New Age of Vertical Construction Verification for Balfour Beatty

It often takes several stakeholders to bring a construction project to life, and for vertical construction developments, there are added complexities with space restrictions and intricate designs to support the upward structure. It’s no surprise then that mistakes happen, but mistakes can quickly drain budgets and take years to rectify. Technology now exists that can spot mistakes before they’re even constructed, create intricate as-built models for verification against design, and do it all in almost real-time. Avoiding mistakes is crucial in delivering a successful project, and efficiency and productivity are key elements for any contractor. With this in mind, Topcon... (read more)

Chasing BIM: How Surveyors Can Shape the Future

Greater Utilisation of Technologies at Hand
While research shows that many organizations recognise the power of building information modelling (BIM) for streamlining construction and infrastructure projects in a seamless online environment, survey and geospatial professionals can do more to deliver value in the 3D environment. There have been countless presentations and papers on the definition of BIM. This article makes an attempt to provide some practical insights on how surveyors can leverage the BIM revolution to benefit their businesses. The good news: there is a general consensus among geospatial thought leaders that the design and construction industry has reached a tipping point. The more that surveyors... (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)

3D Modelling for Construction

When it comes to 3D modelling for construction, what are the advantages and disadvantages of photogrammetry versus Lidar in terms of accuracy, complexity and cost? Breaking away from laser measurement in construction is a taboo subject, perhaps hampering the use of photogrammetry. In construction, aerial survey has enormous time-saving benefits for measuring groundwork areas. Data can be used for asset classification, construction validation as well as health and safety. In particular, regular scans provide a time series of work in progress to detect new issues, managing risk rather than responding to it. This article looks at the state of the... (read more)

How Will the Surveyor’s Role Look in 10 Years’ Time?

Over the next ten years, the surveyor’s workflow will become quicker, safer and easier because of new technologies like scanning, mobile mapping and UAS photogrammetry. Virtual layout, aided by the increasing use of augmented reality technologies, will require fewer physical stakes in the ground. Due to the transformation of the physical world into a digital one, digital twins will take centre stage, with surveyors called upon to convey meaningful information from the model back to the physical world. Demand will increase for surveyors’ expertise in time-based analysis of changing site conditions, such as monitoring installations for volume-changing and deformation analysis.... (read more)
