How can you use drones in 3D laser scanning and land surveying?

Land surveying refers to the detailed inspection and documentation of setting or re-establishing boundaries and monuments of real properties based on historical evidence, existing records, and standards of practice.

The technique of accurately determining the terrestrial or 3D position of points and the distances of angles between them is done by a licensed surveyor to support government and civil law purposes.

Some of these include boundaries of ownership, to establish land maps, locations, and property sales.

Land surveying is also essential in the civil engineering and construction industries.

Almost all property development or even before purchasing a property starts with a land survey. Doing so provides the team with the critical details needed for informed decision making for buying, designing, planning and construction.

Since its conception during ancient Egypt, land surveying in today’s world involves the use of high tech equipment including drones or unmanned aerial vehicles (UAV). With a drone survey, a detailed representation of an area on a map can be developed.

Why Drones Are A Staple in 3D Laser Scanning Technology

In the last decade, drones have been used in many different industries including construction and engineering, mining, agriculture, environmental monitoring, cultural heritage, and more. Today, drone surveying is widely used and availing of a drone survey service from Cambridge Measured Survey will make hard areas to access possible.

Using drones in 3D laser scanning technology is beneficial in terms of accuracy, efficiency, and quality. Industries may have benefited from still images a decade or so ago, but the need for highly accurate data to extract the exact information for clients is critical in today’s market.

Aerial photos taken through drone surveying with the use of advanced photogrammetry are information-rich data for structural renovations, inspections, new constructions, and others. Drone surveying’s ability to capture data from different angles and different types of maps provide numerous benefits.

Time and Cost Saving

Larger sites or land areas can take days or weeks for land surveyors to collect and compile data when using the traditional approach. Data collection via drone survey can be done in hours or days depending on the size of the area. The use of UAV technology combined with 3D laser scanning equates to less time spent in the field and helps speed up the entire project timeline.

The lesser time spent surveying means cost saving. Plus, land surveying or drone surveying can be done any time of the day’ day or night, in a cloudy or smoky environment with a shorter time involved in post processing. This gives surveying companies like Cambridge Measured Survey to finish a project faster and have more time to cater other clients.

Getting a drone survey service from Cambridge Measured Survey is cost saving since you do not need a bunch of staff to do the job.

Eliminates Disruption

Since data capturing is done from above, a drone survey can be executed while in the middle of project operation, busy streets, or even when it is raining. Surveyors do not have to wait for operations to stop or when the street is less crowded to capture data.

Increased Accuracy and Precision

Drone cameras are capable of capturing high definition images at different angles complete with elevation points, data points, geo-references, and colours. These details allow clients to have a clearer view of information compared to manual surveying approach.

The still images and videos captured in a drone survey are a great source of reference for future project explorations.


Land surveying using drones eliminates the risk for land surveyors and the clients’ staff from going to dangerous areas. The availability of drone survey service provides a safer work environment for the land surveyors. With drone surveying, there is no need for surveyors to traverse rocky terrains, visit rail lines, steep slopes, or other high-risk areas. Data gathering in harsh areas, inaccessible areas, or unknown terrain can now be done with much ease.

Land surveyors need not venture into high-risk situations just to get the job done.

Considering the many benefits of drones in land surveying, the use of 3D laser scanning technology and UAV technology together will become a standard in the industry.
