The Advancing Technology of AUVs

A View of the Autonomous Underwater Vehicle Market
Since the last autonomous underwater vehicle (AUV) review in 2016, the market has continued to grow. The biggest market for AUV systems remains the military. The world’s most advanced navies own and operate low-logistic AUV systems for mine countermeasures (MCM) in very shallow waters. These systems can operate in confined areas where MCM vessels cannot. The same systems can also be used in search and recovery operations, hydrography and salvage. This market used to be dominated by a handful of AUV providers, however, the number of manufacturers is increasing. Defence primes are also investing in these technologies through internal development... (read more)

How Can Establishing a UAV Fleet Help Your Business Take off?

Best Practices in Drone Mapping
Unmanned aerial vehicles (UAVs or 'drones') are increasingly becoming the solution of choice and have indeed proven to be a disruptive force across a multitude of industries in the past decade, including for the geospatial surveying profession. But will drones really provide all the answers to your mapping challenges? We interviewed five pioneers in the field to take us beyond the hype, explaining the lessons they have learned from the frontline and sharing their insights on the best ways to introduce UAVs into your business model. What type of work can UAVs be used for? UAVs can serve mapping and... (read more)

Geodesy and Land Administration - FIG Working Week 2017

GW was not at the Working Work in Helsinki in May, but FIG publishes most of the technical papers presented at the conference on its website www.fig.net. Richard Groom has been sifting through the proceedings and has drawn together papers on Geodesy and Land Administration and a few other interesting topics. The code in parenthesis indicates the session number where the papers were presented. It is some time since GW published an article by Chris Rizos on the Global Geodetic Observing System (GGOS). Kutterer (TS03C) provided an update. His paper gave a general overview of GGOS and its work in... (read more)

Christ the Redeemer Reconstructed in 3D

UAV Deployed in Challenging Conditions to Reconstruct Iconic Statue
The famous statue of Christ the Redeemer in Rio de Janeiro has been reconstructed in 3D using a UAV. Challenging weather conditions and the sheer size of the monument meant that careful planning was required to complete the project and maintain safety. Thousands of pictures were captured around the statue and processed to create a large and accurate point cloud and a textured mesh. (By Lisa Chen and Sonja Betschart, Pix4D, and April Blaylock, Aeryon Labs) Fascinating images of the statue of Christ the Redeemer in Rio de Janeiro, Brazil, were seen around the world during last year’s FIFA World...

Understanding the Potential of BIM to Support Heritage Asset Management

Research undertaken under a collaborative doctoral partnership between Historic England and the University of Reading is moving beyond the field of 3D data capture for digital preservation. It considers how critical information for the conservation, repair and maintenance of historic buildings can be visualized in 3D BIM models and how BIM processes can be used for the management of structured datasets that inform conservation and repair programmes. A pilot study has been conducted using the work of the UK Antarctic Heritage Trust and historic British research base ‘E’ on Stonington Island, Antarctica, to consider this potential. Building Information Modelling (BIM)... (read more)

The Role of Surveyors in the Evolution of BIM

Building information modelling (BIM) is becoming more commonplace within construction sectors globally, combining technology with improved collaboration to better manage projects and give them the best chance of complying with time and budget constraints. However, the BIM life cycle and efforts to espouse it are almost futile if surveying is taken out of the equation or, more realistically, brought in too late. It can be good to have a structure that is successfully using BIM to be delivered on time and within budget, but if it or any of its components are in the wrong position the consequences can be...

Introducing the Vogel R3D

Tom Wren, Technical Manager for Rail at Plowman Craven, describes an innovation which seems certain to transform high precision surveying. With more than 20,000 miles of track and 40,000 structures requiring continual inspection, monitoring, renewal and maintenance, everybody working in the industry understands that Network Rail’s need for accurate survey data is vital to the efficient running of our rail infrastructure. In an ideal world, it would be done with nobody on the tracks, without track closures and in as short a time as possible to minimise passenger disruption. Sadly, the current way of working couldn’t be more different. Traditional... (read more)

Thinking Outside the GNSS Receiver Box and Antenna

With so many off-the-shelf GNSS solutions is there still room for innovation? Joël van Cranenbroeck thinks so. One such solution could be based on multiple antennas. But remember, the antenna is still the analogue part that drives the final quality. After decades of research and improvement of GNSS receiver and antenna technology, we have to admit that today solutions are mostly available off the shelf and so you would not expect there to be much room left for innovation. Yet, surprisingly, there are still GNSS applications where there is scope for development. Reliability for Monitoring In geodetic deformation monitoring, for... (read more)

Transition from Providing Solutions to Value Partnerships - INTERGEO 2017

The world’s leading fair and conference on geodesy, geoinformation and land management, recently took place in Berlin and provided an open global environment for the geo-information community and geomatics technology sector to see the current state of the art and look into the future. In addition to Intergeo’s role as a marketplace for the geomatics industry, it helps the global sector to position itself in the changing world economy set in a digitalised world. Characteristics Compared to the last three events, Intergeo 2017 was the first to attract more than 18,000 visitors from 107 countries, with about 1,400 conference delegates... (read more)

What Are the New Global Initiatives for Mapping the World’s Entire Ocean Floor?

Video Included
Three new global initiatives for mapping the world’s entire ocean floor have been announced in London at a special conference organised by The Nippon Foundation-GEBCO Seabed 2030 Project, the international collaborative project to produce a complete, freely available map of the seafloor by the year 2030. They will be overseen by the new Seabed 2030 Director, experienced UK hydrographer and former naval officer Jamie McMichael-Phillips, whose appointment was also announced at the conference. The conference titled 'From Vision to Action', took place at the Royal Society in London on Tuesday 22 October, was convened to mark the progress made in the... (read more)
