Aerial / UAV Surveys

Murphy Geospatial have over 30 years’ experience in Aerial Surveying and Mapping. In recent years we have been leveraging the benefits of using Unmanned Aerial Vehicles (UAV), to capture high-resolution imagery and survey-grade data to reduce potential risk in hazardous, harsh, inaccessible, busy and large-scale sites.


Murphy Geospatial have long understood the benefits of aerial survey and continue to help our clients find the most cost-effective solution for their requirements, delivered via UAV surveys, helicopter or fixed-wing aircraft operationsThe use of UAV (drones) has revolutionised the survey industry in the last 10 years and we have integrated this new technology seamlessly into our daily operationsIn addition, we offer visual inspection of assets using aerial inspection surveys which can avoid the need for costly mobile elevated working platforms or scaffolding. 

An aerial mapping UAV can cover previously inaccessible areas. Large areas of land can be covered in a fraction of the time in comparisonThey can provide contextual information in an urban environment quickly and efficiently without impacting on neighbouring properties. As a result, our aerial mapping services are much quicker and more cost-effective than traditional ground-based methods. High-resolution images captured using UAV can be processed to produce photogrammetry models, digital surface and terrain models, derived point cloud, orthophotography and line mapping. 

Aerial surveys enable the capture of data on a large scale and are generally the best survey option for planning large projects. They can be undertaken using sensors in fixed-wing aircraft, helicopter, UAV and even satellite. Murphy Geospatial consult with our clients to determine their requirements, help them understand the technical aspects and ultimately undertake the aerial surveys in the most cost-effective manner. We capture, verify and manage the data generated to provide high-quality deliverables, maximising the benefits of this technology for our clients.

Aerial / UAV Surveys - Murphy Geospatial

Murphy Geospatial have built up a wealth of technical knowledge over our 30 years’ experience delivering data captured through aerial methods. We find our clients lean on this experience when deciding the best approach for capturing data for their projects. We can advise on the benefits of photogrammetry vs. LiDAR and achievable accuracies of different aircraft and survey methodologies. We will consult with our clients to understand their technical requirements and budgets before recommending a course of action.  

Aerial photogrammetry and orthophotography are produced from photographs captured by UAV operations. This cost-effective solution produces vivid outputs from which features can be identified for traditional survey deliverablesThey require good light and will capture everything in the line of sight of the camera. Aerial LiDAR mapping enables the capture of rich datasets and can operate in poor light conditions, through vegetation and tree cover and in some cases can be more cost effective in the long-term.  

We own a fleet of modern UAV and employ experienced, licensed pilots. Our flight planning ensures that all relevant authorities are aware of our flight operations and suitable weather windows are chosen to maximise the quality of captured data. The high-resolution data captured from our aerial surveys is checked by our pilots in real-time to ensure all areas in the scope are covered. Geospatial accuracy of the captured data can be increased using verified ground control points or areas. It can also be fully integrated with data from other survey instruments, giving you the ability to access all required information in one consolidated place.  

End-to-end consultancy and project management means that Murphy Geospatial will provide our clients with professional liaison with landowners, utility providers, authorities, and any relevant third-parties. 

Murphy Geospatial understand that our client’s requirements can change from project to project. A large linear project such as a road development project will have different requirements to a housing development project. An urban streetscape redesign project presents a particular set of challenges which will differ to those for a coastal erosion study. What these projects do have in common is that they can all benefit from the economies of scalespeed and volume of data generated through aerial surveys. Using our people, process, and latest technology, underpinned by our GeoCert™ platform, we provide geospatial certainty in aerial surveys for our clients.

Aerial / UAV Surveys - Murphy Geospatial

Murphy Geospatial offer a range of aerial mapping and aerial inspection services.  

Our aerial inspection services leverage off the control and flexibility of UAV to generate high-quality, high-resolution images and videoOur skilled pilots can reach difficult to access locations and make use of proximity sensors to get as close as possible to the area of interest without damaging the aircraft. We can supply an immersive video headset with wireless link to the UAV camera so that our clients can get a real-time understanding what is in the field of view of the aircraft and advise our pilot on areas of particular interest. Our clients have found this useful for structural inspections and traffic studies. 

For aerial mapping services there are generally three options: 

  • UAV for small to mediumsized areas e.g. development sites 
  • Fixed-wing aircrafts for large areas e.g. flood plains  
  • Helicopters for large areas with a high-accuracy requirement e.g. large-scale mapping of electricity cables or railway lines 

A growing number of sectors are experiencing the benefits of using aerial survey to better understand their assets, optimise their survey requirements, and reduce risk in their maintenance operations. 

  • Infrastructure: RoadsRail  

Reduces the need for of rail possessions or traffic management on roads, preventing costly knock-on effect of delays to rail services and trafficThere are health and safety benefits of taking surveyors out of dangerous transport corridors. Enables the capture of larger, more comprehensive datasets to better understand assets. 

  • Infrastructure: Bridges, Dams 

For visual inspection of inaccessible areas. Photo and video outputs can give engineers an understanding of any visual defects without the need to set up scaffolding MEWP or rope access. 

  • Property, Heritage, Archaeological 

For asset inspection / rooftop assessment in order to detect any damages or defects. UAV surveys can access large sites easilywithout affecting the site and avoiding the need for scaffolding or MEWP. Detailed outputs can provide a record of detail on heritage buildings to plan restoration. 

  • Construction 

UAV are being used more and more in the construction sector. Progress update aerial surveys from UAV can be processed and compared against BIM models to provide an understanding of progress against programme. Projects involving the movement of large volumes of earthworks can leverage the benefits of aerial surveys for stockpile management and quick calculation of quantities. 

  • Energy, Renewables, Oil and Gas 

For visual inspections of inaccessible areaswithout impacting operationsFor aerial inspections of turbine blades and towers to highlight damage and identify defects. 

  • Hydrographic 

Coastal and inland waterway surveys to capture large volumes of data from large-scale sites for coastal defence, coastal erosion and flood modellingAlso useful to capture video footage of flood extents to gauge impacts and plan emergency response. 

  • Marketing 

Highres video and imagery, which can be used for marketing purposes.
