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.

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.

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.

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.

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.
