High accuracy train borne surveying of the railway using multiple sensors

Bryce Lane, Commercial Director, Omnicom Balfour Beatty

Dr Jonathan Owen, Expert Engineer, 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.

Bryce has nearly 20 years experience in the rail industry including roles in finance, construction, safety and systems engineering and information management. He has worked on numerous asset implementation, surveying and inspection projects from both client and supplier side and has worked for Omnicom Balfour Beatty since 2012 in a Business Develop and Account Management role.

Dr Jonathan Owen began working for Omnicom Engineering in 2001 after completing his PHD in Applied Mathematics. He has been instrumental in developing Omnicom’s world class surveying and positioning systems. As part of a team he has developed a set of geospatial mapping tools sitting above an Oracle database which allow network infrastructure owners to view and manipulate their linear and fixed asset data as well as manage services provisioned over these assets.

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.

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.

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.

Case study 2: does a smart city have to choose between standardisation and innovation?

Richard Woodling, Managing Consultant, Smart Practice, Ordnance Survey

What makes a city smart? A consistent theme is that it involves considering a city as a whole, rather than as a number of separate systems. For instance, making choices about transport, green spaces, air quality and health in a joined-up way can help make a city a more attractive and liveable place to live and work. However, cities are diverse. There is no one-size-fits-all formula which a city can adopt to make it smart.

GeoMOVE: merge regional geological parameters with measured ground motion for the transport sector

Claire Roberts, Remote Sensing Consultant, CGG - NPA Satellite Mapping

Ground instability is present in many areas of the UK and can be due to natural geological processes such as shrink-swell clay or activities such as groundwater pumping and old mine workings. Conventional surveying techniques are capable of measuring surface movement and on-site monitoring networks can be installed in regions influenced by ground motion. However, it is not practical or cost-effective to install a large regional scale in-situ measurement network. Satellite imagery makes this possible and combined with geological information has led to the development of a unique source of regional ground stability data (1:50,000) called GeoMOVE (Geological Motion Observations & Velocity Evaluation), a targeting tool that identifies.
