Surveying

Seminar Session

Today surveys are undertaken in a disparate range of seriously challenging environments, such as polar regions or the deep sea. A wide and growing variety of sensors can be deployed, along with software utilising mathematical feature recognition techniques. But in human de-skilling the question arises, can robots really mix better cocktails or is the bar person still an essential part of the mix?

Surveying in Antarctica – Blue Ice Runways for Large Jets

Ian Stilgoe, Vice President Geopositioning Europe, Topcon

The utilisation of Blue Ice in Antarctica for landing aircraft is not a new concept. But with glaciers on the move and changing sea ice conditions it brings new demands and challenges for servicing scientific bases and visitors in this remote continent. The extreme climate makes for special requirements when undertaking surveying and research to determine the potential suitability of a site for use as a “certified runway”.

Desktop studies by Antarctic Expeditions and Logistics had identified potential sites from satellite imagery and radar data and an area of interest was defined for closer inspection and surveying as a potential new runway for large jet aircraft.

Do robots make better cocktails? Deskilling of data capture risks loss of human input

Peter Cave, Director, Meridian Surveys Limited

In 1988 a presentation at an ESRI conference in Rome (Cave, 1988) on the use of GIS in mine warfare countermeasures proposed mapping the seabed at periodic intervals and comparing the data for anomalies indicating the possible presence of a mine. At University College London (UCL) survey students are instructed in mathematical techniques for removing outliers from hydrographic survey data. These two examples have incompatible philosophies and amply illustrate the importance of understanding data and how it should be interpreted in order to be fit for purpose. With new technologies it is important to realise there is a human factor dilemma caused by deskilling the data capture. So the question is not whether robots can mix better cocktails but how to retain the expertise of the bar person.

After a career in shipping (navigating officer with P&O), Peter worked in the City with P&O, Euro-Baltic Shipping and then Rio Tinto. His directorships include Qubit (manufacturers of survey equipment) and KBC (oil industry consultants). He, thus, has experience as both a provider and user of survey data.

Peter studied international transport at Cardiff University (UWCC) and surveying at University College London (UCL. He has run his own companies operating in London, Africa, Russia (FSU) and USA. Peter has previously presented papers on transportation in London and Prague, mining industrial minerals in Dumlupinar, Montreal and London, and Geographic Information Systems in Rome.

Who would use centimetre accuracy on a smartphone and what would this innovation mean for the geospatial industry?

Richard Gauchwin, Business Area Manager for Mapping and GIS, KOREC,

Gareth Gibson , Business Development Manager, Trimble Geospatial,

Trimble Catalyst is the world’s first software GNSS receiver designed to run on Android phones and tablets and when used in conjunction with a small ‘plug and play’ low-cost digital antenna, turns these devices into cm accurate data collection tools.

This is a new era of GNSS technology and a new business model – software as a service (SaaS). It’s available as an on-demand subscription service and offers a range of accuracies from 1m to centimetre level, priced accordingly. In short, it puts affordable, cm accuracy into the hands of any industry in the world that uses smart phones, which is pretty well all of them!

Richard has worked for KOREC for 15 years specialising in GNSS and Mapping Technologies. He is involved in the introduction of the Catalyst solution to the UK market and integrating it with existing Workflows.

Gareth Gibson has worked in a range of product and technology development roles in the geospatial sector for 15 years, with a particular emphasis on GNSS technology and its use in the GIS sector. Currently working as a Business Development Manager for Trimble, Gareth is passionate about the power and potential of geospatial innovation and technology to transform the way work gets done.

Continuous As-built – the truth about Construction Validation

Andrew Evans, Product Manager, Topcon,

In 2015 near real-time construction validation was possible. The hard facts though, were that the procedure’s complexity required specialist survey and scanning teams and was

only of interest to projects totally committed to the philosophy of Digital Engineering. Balfour Beatty are one of those companies leading that digital charge. In 2018 they now have access to a solution for near-real-time construction validation utilising a combination of hardware and software, enabling site engineers and not specialist survey and scanning crews to complete day-to-day validation tasks in a third of the time previously required. Huge time and cost savings result. Costly mistakes and project hold-ups are avoided.

An automated total station system for the Northern Line extension

Bruno Norberto , Head of Geomatics, Geotechnical Observations

NLE is the first major extension on the London Underground network since the Jubilee Line in the 1990s. The scheme consists of two 5.2m internal diameter, 3.2km long tunnels starting at Battersea Power Station, passing through Nine Elms Station and on to two shafts at Kennington. Two sprayed concrete lining (SCL) tunnels advance the TBM tunnels to a section of the Northern Line called the Kennington Loop. The SCL tunnels connect to the existing tunnel through two step plate junctions (SPJ) with new stations at Battersea Power Station and Nine Elms.

Geotechnical and structural monitoring have been deployed.. The presentation will focus on 24/7 automatic monitoring using automatic total stations supported by manual readings from BRE sockets and barcodes used to monitor buildings.

Geo Immersive Reality (GIR)

Layla Gordon, AR/VR lead in OSLabs, Ordnance Survey

Maps are a reference to real world objects. They help us navigate and make sense of the world by providing a list and locations of places and objects and a drawing to help understand the attributes of objects invisible to our eyes. The height and contours of a mountain, the dimensions of a property,  etc, all relevant to help understand the environment. However, if this geospataial information is to help the user understand the world in their current location, it makes sense to use Augmented Reality to add the geospatial attribution of real world objects as a digital overlay and to be visualised by a smart phone or glasses.

The level of immersiveness has been proven by psychologists to improve information retention by 20%.

Different paths to the same destination – a range of techniques to produce complete point clouds

David Andrews, Geospatial Imaging Analyst, Historic England

It has long been an axiom that a single method is rarely sufficient to produce a complete survey. Surveyors have a toolbox of techniques. Now that most measured building surveys and 3D models are derived from a point cloud it is expedient to use whatever tools are appropriate to produce a complete cloud. The accessibility of photogrammetry and drones along with hand-held laser scanning and mobile mapping systems, means it is now possible to capture data in inaccessible areas or where it would previously have been uneconomic. A number of case studies will be used to examine the advantages and potential pitfalls of using a combination of techniques but will ask the question, is the pencil and tape measure still one of the most efficient tools?

Mobile Mapping, a 21st Century tool for the construction industry

Mark Reid, VP Product Management, GeoSlam

The recent collapse of Carillion and profit warnings of rival Capita, must act as a wake-up call to the construction industry. For too long, cost and project overruns have been considered a necessary but unavoidable evil. This must change. The Government’s Digital Built Britain programme, unveiled last year, focuses on the transformative power of BIM and how fully embracing digital construction leads to more efficient working practices, greater collaboration, and ultimately, more projects delivered on time and on budget. The beating heart of a project is the 3D BIM model – one which is current, built in an open data format, accessible and understandable by all project stakeholders. Mark Reid will be showing the role handheld, mobile mapping plays.

Imaging Total Stations – Static and Dynamic Monitoring without Prisms

John Brewster, Managing Director, Imetrum Ltd

What if you could use a robotic total station (RTS) for monitoring, without prisms? Imagine the savings in set-up time and access costs. What if this device could also give you multipoint monitoring data at 100Hz? With the integration of cameras into many high end Total Stations (Trimble SX10, Leica Nova…) and advances in image processing, this is not so far-fetched. Surveyors are already using images for improved reporting, identifying targets during DR measurements, and for measurement (photogrammetry). Trimble’s Vision whitepaper identifies a bright future ahead, as does European research. Paul Waterfall will discuss the current state of the art for monitoring using an image assisted RTS, and the potential impact on prism and laser-based tracking.

Automated monitoring in the digital era

Marco Di Mauro, Segment Manager, Leica Geosystems

Automated monitoring solutions have been driven not only by advancements in measuring technology but also by the availability of new telecomms or computing solutions. Thanks to the power of modern hardware and new software algorithms, automated scanning processing and real-time surface comparison are now possible, opening the door to monitor in real time any structure virtually without the need of prisms. High-resolution imaging is now possible thanks to faster telecomms infrastructures saving time and money for site inspections and visual checking, which can now be done remotely in the field via wireless mesh and computed in the cloud.

Emerging immersion in construction

Martin McDonnell, Chairman and Founder, Soluis Group and Sublime

Communication is key: site induction with work zones described on a 2D plan doesn’t make sense until you step foot on site. We communicate by sight, sound and shared experience. The best work gets done by teams with shared goals and shared experience of the challenge at hand. The application for health & safety and site communication is clear for this technology but where are we headed and what can we expect in the realms of shared experience and the augmented worker? The presentation will look at the Soluis’ portal and discuss advantages of being able to experience and plan the site virtually in a shared space.

BIM: Through a surveyors’ lens

Dipaneeta Das, CAD Technology/BIM Manager , Warner Surveys

BIM is gradually transforming and ushering in a digital revolution in the construction sector, increasing efficiency and reducing risk. The process generates information models that can be used throughout the asset’s lifecycle. The onus is on the whole supply chain to develop information models. It implies that standardised processes and agreed methods are to be followed in a collaborative working environment. Hence awareness and understanding of BIM by the supply chain is critical for project success. A key member of the supply chain is the surveyors. They address topographical and positional challenges in construction projects, capturing existing scenarios to provide data rich/intelligent 3D models. This presentation from Warner Surveys highlights the role of surveyors and asks will their role change?

The importance of specification and metadata within heritage survey

Paul Bryan, Geospatial Imaging Manager, Imaging Team, Historic England

Published in 2000 the ‘Metric Survey Specifications for English Heritage’ was the organisation’s attempt at describing the technical requirements for metric survey – the acquisition and presentation of base data undertaken in support of conservation and understanding of the historic environment. Now in its third edition, this specification is widely used by heritage professionals when specifying survey work.  However, with an ever expanding toolkit of technologies, how can such documents keep up to date and what items should the fourth edition include when published in 2019? What level of metadata should be provided with every acquired survey dataset to ensure it is fit for purpose both now and ideally in the future?

Use of Unmanned Aerial Vehicle (UAV) Technology to aid terrestrial scanning for Reality Capture & BIM

Keith Wakeley, Drone Survey Instructor, Drone Pilot Academy

Capturing reality using terrestrial laser scanning is now part of the BIM workflow. Huge quantities of data can be captured quickly. Access to roofs, difficult to reach areas or dangerous structures however, present a hurdle to capturing the full picture. UAV technology, together with  photogrammetric software and increased computing power, enables us to capture this missing data quickly and safely with usable deliverables. With pre-planning and an integrated workflow we are able to combine data of facades with photogrammetry derived point cloud data of the upper elevations and roof to produce a coherent, accurate point cloud model of the external envelope of buildings for feeding into the BIM workflow.

Addressing the supply chain: the true ROI of UAV survey services

William Tompkinson, Principal, Insightful Dimensions

Reasons for utilising UAV surveys are discussed in terms of speed, accuracy and sensor choice. However, this can be a very short-term and insular view to whether UAV surveys are bringing benefit to customers. There is typically little discussion of the implications on supply chains. Drawing upon experiences of Canadian UAV survey company, Sumac Geomatics, in undertaking monthly volumetric monitoring contracts, this presentation will expand the scope of how we assess the impact of these activities. It will illustrate how when monitoring stockpiles, there can be technical decisions made by the UAV provider that will directly influence supply logistics and just-in-time strategies.

Using UAVs and photogrammetry for surveying road and railway embankment and cutting (earthmoving)

Siim Solovjov, Engineer, EIK Infrakonsult OÜ

Digital surface modelling using small unmanned aircraft systems (UAS) and photogrammetry have made huge advances in recent years. This great advancement in technology has created a serious alternative to traditional surveying methods like GNSS based measurements, tacheometry or laser scanning. For areas ranging from 1000 m2 to 10 ha and up where accuracy requirements are between 2-10 cm in elevation, it is an ideal tool to complement traditional surveying techniques.

Applications for digital surface modelling from photogrammetry are wide and it has found its way to fields from agriculture to virtual reality environment design. This seminar paper is focused on solutions and practices for using these advancements in surveying road and railway embankment and cutting (earthmoving). It also addresses how various aspects of technical choices affect the outcomes of using UAVs as surveying devices.

This seminar paper examines different technical, business and regulatory obstacles that need to be overcome to take full advantage of this new technology and make it one useful part in a box of tools in evaluating earthmoving volumes more efficiently. Experience is drawn from using different flight and camera platforms, workflows and software solutions in different road and railway construction projects, including failures and successes over last couple of years.

High resolution multi-lane road surface mapping using 3D laser profilers

John Laurent, VP and CTO, Pavemetrics Systems Inc.

Highway ministries require annual inspection of roads and infrastructure for planned maintenance. Road surface defects need to be measured and serve as input data to pavement management software. Defects are likely to be measured using 3D laser sensors which acquire the shape of the road surface. Once the condition is determined that the road has degraded and needs renovation and resurfacing, then a high-precision survey of its surface is used as an input to 3D CAD road design software to control 3D pavers and milling machines using laser-tracking total stations. We propose to reuse the 3D road surface condition data to create the road surface model to avoid manual road surface surveys requiring road closures.

Utility Survey Exchange

Dr Neil Brammall, CEO, Utility Survey Exchange

Accidental damage to buried utilities poses danger to life and limb, interrupting critical services and costs time and money. The societal cost of a utility strike is estimated to be around 30 times the cost

of repair. More importantly, people die each year and many more receive life-changing injuries. Inaccurate and incomplete recording of buried assets has been identified as a major contributory factor to accidental utility strikes. Utility plans, like the infrastructure they represent, are often old and captured before technology allowed accurate positioning. Buried assets are routinely recorded relative to above-ground features which have moved or been removed.

Wouldn’t it be great if accurate and constantly refreshed data was made available to utilities? Utility Survey Exchange is a platform which seeks to close that circle.

The impact of autonomous surface and aerial vehicles for Coastal Monitoring and Engineering

Duncan Mallace, Managing Director, 4D Ocean

Driven mainly by the remarkable technological progress in Unmanned Aerial Vehicles (UAV) surveys and military requirements, 2017 proved to be the first year when it was possible to conduct a fully autonomous coastal survey for the bathymetry as well as the topography using a combination of Autonomous Surface Vehicle (ASV) and UAV.  ASVs and UAVs enable survey companies to reach coastal areas which have either been too hazardous or too shallow to reach with normal vessels or terrestrial means.  It is also possible to deploy an ASV directly from the shore at the survey location, rather than having to sail from the nearest port. This increases the efficiency of the survey as well as reducing the cost.  The UAV photography is essential for mission planning of the USV. Flying the UAV at low water enables dangerous shoals to be seen and therefore avoided. The shallow draft of the ASV means that if it can’t be seen in the UAV data it is too deep and therefore safe for the ASV.  4D Ocean was the first survey company to perform a fully autonomous survey and this presentation details the acquisition and processing methodologies, issues that were found and benefits that compared with traditional means. It presents the data and discusses improvements and future challenges.
