Laser Scanning

Seminar Session

Laser scanning has enabled new applications for geospatial data as well as replacing traditional survey techniques. For property managers moving to BIM laser scanning can create as-built digital models of their facilities, while contractors and surveyors have a tool that can rapidly capture a database of 3D geo-referenced information. But will it make survey sexier and are we doing it right?

Survey to BIM – is it BIM or 3D representation, are we doing it right?

Enzo Labrosciano, Head of BIM, Murphy Surveys

Where does traditional surveying and laser scanning fit into the BIM process?

With no clear consensus given by our industry, and LOD dictated rather than lead driven, the ease of access to open data and accuracy improvements, has surveying missed its chance to impact change. What are expectations of LOD’s, should there be a standard in Surveys or is it up to the client to ask for what they need. Is it the case that this is client dictated or should Surveyors take responsibility for LOI, and what would that include.

Where does open source data and changes in technology, such as through photogrammetry on mobile devices and ‘drones’, leave the survey industry? Or, has the construction industry simply moved on and left surveying behind? We will be reviewing the implications of using of this data, and what role the surveyor plays in this.

Enzo Labrosciano is Head of BIM at Murphy Surveys and is responsible for spearheading the company’s BIM processes, advising clients on best practice, implementing innovative workflows and developing one of the largest in-house BIM teams in the UK, with over 100 high quality as-built BIM models produced in the last year alone.

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.

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.

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?

Multisensor photogrammetric platforms – the answer for urban smart cities worldwide

Witold Kuznicki, Key Account Manager, MGGP Aero

The presentation will show how a multisensor photogrammetric platform, which took almost two years to design, can simultaneously capture geodata. This scalable and combined configuration allows acquisition of nadir and oblique imagery and LiDAR simultaneously. So one multisensor platform collects all the data which is needed to map a city from each of four directions and in 3D. The application includes processing tools and internet publishing TMS (tile map service) without having to install additional plug-ins.

Use of Unmanned Aerial Vehicle (UAV) technology to aid terrestrial scanning for reality capture and 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.

Ocean garbage patch detection in 3D using hydrographic LiDAR

Fabrizio Tadino, Technical Sales Manager, Teledyne Optech, Inc.

Over 5 trillion pieces of plastic litter the world’s oceans in five main patches, the largest one being the Great Pacific Garbage Patch (GPGP) located in the North Pacific Ocean between Hawaii and California. The Ocean Cleanup Foundation, a not-for-profit that develops technologies to rid the world’s oceans of plastic, needs a reliable method to understand GPGP’s dimensions and predict how many tons of rubbish are to be extracted. Their Aerial Expedition project in 2016 used aerial surveys to quantify the amount of large plastic debris in the GPGP, and Teledyne Optech’s CZMIL (Coastal Zone Mapping and Imaging LiDAR) was utilised to fulfill The Ocean Cleanup team’s goal.

Direct geopositioning with low cost drones

Lewis Graham, President/CTO, GeoCue Group Inc

Mapping by drone is a cost effective solution for collecting geospatial data, from simple orthophotos to complex differential volumes. With the exception of simple visualisations such as video, all mapping products need accuracy. This presentation will define accuracy and review the requirement of various products. The range of options in to achieve such accuracies will be presented and the importance of camera calibration will be discussed. Direct geopositioning using low cost drones reduces and sometimes eliminates the need for ground control points. A series of real world mapping projects will demonstrate how direct geopositioning can be used to reduce on-site time and overall project cost.

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.

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.

Using UAV and mobile LiDAR surveys to drive efficiencies in flood defence management on the Thames

Dan Culli, GIS Consultant, Critigen/TEAM2100

The Thames Estuary Asset Management 2100 (TEAM2100) programme is the Environment Agency’s largest flood-risk programme and involves new ways to manage flood defences. With 4,000+ assets, including over 350 km of walls and embankments, the collection of geospatial information is key to our asset management approach. We looked at a variety of techniques to capture asset information and identified the use of drone technology as an enabler for efficiency, safety and data quality. We attached multiple sensors to drones to capture 3D topography, HD aerial photography and 4k video – all geospatially referenced. All data is stored and viewed in the Estuary Eye, a GIS viewer available to all team members.

Case Study 1: analysis of crowdsourced data from a distributed network of cyclists in Manchester

Philip McAleese, CEO, See.Sense

Like many major cities around the world, Manchester (UK) has had to contend with increased levels of urbanisation and population growth as people move to the city. With this trend expected to continue, the city’s transport infrastructure is facing increased strain as a rapidly expanding population navigate their way through the urban environment. It has therefore become a top priority to understand patterns of mobility to improve the transport network and maximise living standards. See.Sense, in collaboration with researchers from Queen’s University Belfast, is working with CityVerve, to build a more connected and mobile city through the use of sensor technology to identify its rapidly changing transport needs.

High accuracy train borne surveying of the railway using multiple sensors

Bryce Lane, Commercial Director, Omnicom Balfour Beatty

Traditional surveying techniques on the railway are costly and dangerous. To perform surveys safely, lines must be closed to traffic so night time surveys are common. Vehicle-borne surveying systems mitigate many risks and constraints by operating in traffic from the safety of a vehicle.

Omnicom Balfour Beatty have developed OmniCapture3D which consists of two high resolution lasers, a calibrated HD camera and a highly accurate inertial positioning system. Improvements in the timing system allow OmniCapture3D video and laser profile data to be used for performing sub-centimetre absolute accuracy measurements.

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.
