Drones are transforming the way we see the world
A drone is an Unmanned Aerial Vehicle (UAV). UAVs can either be Fixed-Wing drones or Multi-Rotor drones. A drone survey gives an unrivalled bird’s eye view of your project.

Fixed-wing drones have a longer flight time/range but are less manoeuvrable
As drones get more affordable and versatile they are becoming more accessible to all sorts of people who would have never been mapping before. However, a professional surveyor who has an in-depth understanding of modelling the real world can produce better quality models. Qualified Surveyors have an in-depth understanding of measuring and modelling the real world. Surveyors understand what goes in has a direct bearing on what comes out. Building in precision means a process that often involves work without a single point being measured. A full understanding of precision and repeatability and a rigorous approach to data gathering transforms average data into precise data that is also accurate. Efficient workflows, compliant with the CAA GVC using survey-grade DJI drones underpin that. Drone surveys leverage all the benefits of drones with our surveyor’s knowledge and experience to give you superior results.
Accuracy and precision aren’t the same
We provide the following drone surveying services:
- Drone Mapping: Photogrammetric or Lidar surveys. Drone mapping is far quicker to measure than a conventional topographical survey. Comparable survey-grade data is achievable with the correct workflow.
- Drone Inspection reports: Roof and inaccessible location inspection, condition and thermographic reports. These can be particularly useful when inspecting equipment where safety is a concern.
- Drone progress monitoring reports: repeated flight monitoring and progress for construction and civil works.
- 3d modelling / digital twins: 30 years experience of in mapping and modelling the real world.
- Measured building surveys particularly in difficult-to-access areas using autonomous drone surveys and state-of-the-art collision avoidance technology.
- Assessment management surveys: quickly map your assets, know where they are, their condition and other data sets imported into your GIS system
- Crop surveys: Map your farmland with ease and routinely monitor your crops.
- Videography: Video footage can be great for cataloguing assets or recording events.
- Photography: Photos can also provide a great record of assets and events.

Ground Land Surveys evolve with drones
We have over 30 years of experience as Land Surveyors. Professional land surveyors have seen many changes over the years as technology changes have yielded huge productivity increases.
- Years ago optical theodolites were used by a team of 3 to 5 Land Surveyors to manually record the observed angles and distances from known stations. Angles were optically read from glass circles. Tapes were used to measure distances. Measurements were logged by hand into field books. The measurements were transcribed using sheet compasses onto drafting film as a point plot with linework added using ink pens and French Curves.
- Electronic Distance Measuring devices appeared replacing the survey crew members that were handling the tapes. Greater distances were measurable reducing the number of stations required to carry out a survey.
- Later electronic theodolites replaced the glass circles. Data loggers appeared that allowed recording of angles and distances.
- More recently Robotic One-man Total Stations appeared reducing the survey crew to just 1 surveyor operating the instrument remotely from the detail pole.
- The advent of survey-grade Global navigation satellite systems (GNSS) / Global Positioning systems (GPS) was later transformed by Real Time Kinematics (RTK) supplying corrections in real-time via mobile signals. Now we are seeing that transformed again by the arrival of survey-grade Unmanned Aerial Systems (UAS).
Drone surveys have now elevated the survey workflow to a whole new level. Drone-based land surveys, using photogrammetry and Lidar remote sensing technology, are allowing land surveyors to literally reach new heights of data acquisition. The deliverables for our clients are equally impressive with visually stunning and precise 3d models. Contact us if you would like to see how these deliverables can transform how you do business.
Drone Survey: Enhancing Measured Building & Land Survey Data | Crucial Services
Why is using a qualified land surveyor important?
In the UK anyone can call themselves a surveyor without any qualification in surveying. However, most surveyors work for reputable companies and have spent years qualifying as surveyors. They have gained knowledge and understanding through their qualifications and work experience and are members of professional bodies. Professional bodies uphold standards and monitor surveyors continuing professional development.
With the rise of drone technology, many hobbyists have become commercial drone pilots and are leveraging the benefits drones bring to surveying. However, such pilots may not be qualified as surveyors or carry the same level of insurance as a surveyor, making it important to use a qualified land surveyor for a proper understanding of a site’s topography and setting. Finding an experienced and trusted surveyor is essential if you are a construction site manager, building developer, asset manager, project manager, facility manager, architect, planner or quarry manager.
