Murphy Surveys Monitoring Department provides sensor equipment and manual monitoring services.Using examples from actual and past projects we will show our multi-technology approach to monitoring design, where sensor integration allows faster and more accurate data interpretation and increases the overall solution resilience and reliability.While modern software platforms allow results comparison, Murphy Surveys is working to bring the integration to a deeper level where the data are integrated from the computation stage to produce better results including GNSS data trends to improve Robotic total station networks where stable points are not available.

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.

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.

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.

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.

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.

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 GeoMOVEâ„¢ (Geological Motion Observations & Velocity Evaluation), a targeting tool that identifies.
