Laser Scanning

Murphy Geospatial pioneered the use of laser scanning for commercial surveys in the early 2000s. Murphy Geospatial continues to innovate and lead the market in laser scanning today.


3D laser scanning remotely captures the complete three-dimensional geometry of objects efficiently and accurately. It uses laser range finding technology in a systematic way to measure a high level of detail in high volumes. A huge amount of detail can be collected in a short period of time whilst maintaining survey accuracyIn addition, the laser technology utilised permits the scanner to work in poor lighting conditions without affecting the quality of the survey. 

The point cloud data captured can be post-processed to extract features from the data. This can feed into more traditional CAD deliverables or be processed into 3D models such as BIM deliverables depending on our client’s requirements. Laser scanning typically generates very large datasets. We offer solutions to manage and visualise this data to ensure our clients maximise the value of their information. 

Murphy Geospatial continue to innovate in laser scanning applications. We were approached by major manufacturers to test and become early adopters of mobile scanning technology. Mobile laser scanning, or mobile mapping, combines data captured by multiple laser scanning instruments and cameras mounted on a vehicle, with positional information from other sensors, to provide comprehensive data capture along linear projects.

Many of the sectors we work in require all-encompassing surveys where large amounts of detail are required to a high level of accuracy. Assets with complex geometry such as pharmaceuticals, manufacturing facilities, commercial construction, heritage buildings, infrastructure construction and maintenance all rely on the detail provided through laser scanning. Murphy Geospatial are pioneers in the use of laser scanning technology and continue to push the industry with new applications of the technology. A well-planned and executed laser scanning survey is often the first step to digitising an asset, allowing our clients to leverage the use of BIM and other digital technologies to manage their portfolio.

As with any of our survey services, our approach is to consult with our clients to determine their exact requirements. Terrestrial laser scanning surveys typically form a small percentage of overall project cost but provide excellent value in the form of a single source of truth for a project which can be used throughout the project lifecycle.  

Once awarded a project we employ a well-established project delivery workflow, based on our 37 years of delivering over 20,000 surveys. The key to a well-executed laser scan survey is pre-planning. A laser scanner can only capture features that are within its line of sight, however, capturing scans from multiple positions can be combined to provide a comprehensive capture. We take great care in planning our laser scanning surveys to optimise the number of scans required to create a full capture of the survey areas. 

Our equipment is regularly calibrated and upgraded to ensure we utilise the latest technology and firmware. Ongoing investments in the latest technologies enable us to cut costs and risks for our clients. We have an array of systems available to meet any requirement, including the Mobile Mapper (vehicle-mounted), Aerial LiDAR, terrestrial and handheld scanners. We use a portable coordinate measuring machine with integrated laser scanner for close range laser scanning. This technology is a fully integrated high definition 3D measurement solution for applications that require metrology grade precision. 

We have developed our own exclusive, in-house 3D surveying and CAD/Revit modelling techniques. Our laser scanning and BIM departments work hand-in-hand to deliver models with amazing level of detail and complexity. The processing of point cloud information is a rapidly developing sector with feature extraction now beginning to be assisted by artificial intelligence and machine learning. With the support of our innovation and technical departments, we are beginning to adopt these processes to streamline our own processing workflows, ultimately passing on this saving to our clients. 

Murphy Geospatial are the most experienced users of this technology in Ireland and the UK today. We find the main benefits of this technology include: 

  • Remotely capture data from potentially hazardous sites, e.g. motorways or structurally unsafe buildings 
  • Fast data capture; critical on sites with limited access, e.g. crime scenes 
  • Complete data collection enables further investigations to be carried out later on without costly returns to the site 
  • Reduces the costs and downtime associated with construction rework, site revisits and field changes 
  • 3D Laser Scanning is a lower cost survey method compared to alternatives 
  • Improved accuracy and precision reduces the risks associated with project execution 
  • Highly-detailed data improves decision-making and engineering designs 
  • Enables 3D Modelling and Building Information Modelling (BIM)

Acquisition of geospatial data via laser scanning opens up a range of delivery options for our clients. Murphy Geospatial predominately deliver point cloud (coloured or uncoloured, Truview), extracted 2D or 3D features in CAD drawing (.dwg or .dgn) or BIM models to varying levels of detail (LOD100 – 500). We can add attribute data according to our clients requirements. We also provide federated data where we captured topographical, utility, or aerial survey data. This will be geospatially coordinated to provide the best framework for progressing the design of projects.  

Laser scanning derived deliverables are often large, complex datasets with significant file sizes. We offer solutions to manage and visualise this data to ensure our clients maximise the value of their information. Users can view, pan, zoom, measure and markup without the need for CAD or 3D skills. This is available through standard internet browsers, typically without the need for additional plug-ins. Our geospatial management service can provide further assistance where our clients have multiple datasets for a project or across their portfolio.
