What Makes Drone Surveying the Most Convenient Tool Today?

What Makes Drone Surveying the Most Convenient Tool Today?

Flying Mini Robots, Miniature Pilotless Aircraft, Unmanned Aerial Vehicles (UAVs)—many names to establish this beneficial equipment, drones are now some of the most popular technological advancements in the world.

Drones have broken a lot of barriers and limitations in many industries, especially in construction and engineering where drone surveying is now a massive trend around the world.

But what exactly is drone surveying and why is it considered one of the most convenient tools of the modern age?

Getting to know drone surveying methods

Drone surveying is a field in 3D laser scanning where a drone or unmanned aerial vehicle (UAV) with downward-facing sensors are used to capture data from an aerial perspective.
LiDAR payloads and multispectral cameras are just some of the most commonly used sensors for drone surveying because they offer clear images and accurate measurements from different angles using images that are tagged with coordinates.

Drones offer a unique perspective into surveying lands and surfaces, and they also have photogrammetry capability that allows for easier rendering through point cloud survey that produces extremely detailed 2D and 3D maps.

These models can also be enhanced to project elevations and offer information such as volumetric measurements or distances, which are useful for planning, design and upkeep of buildings as well as creating cadastral property boundaries.

Aerial mapping also allows us to keep record of literally everything in the world. A recent study displays where in the UK has most and least trees through aerial survey and mapping.

The benefits of drone surveying

With the use of drones, surveying teams are now capable of acquiring data from a vantage point that’s impossible for humans to access.

For many years, surveyors had to go through rough terrains and put themselves at risk just to take measurements of spaces that will be used for creating representations for projects. But drone surveying by Nottingham Measured Survey is set to change this by offering these benefits:

• It offers the most accurate data from surveys.

Static Nottingham 3D laser scanning services may already be accurate in offering point cloud data for different structures, but drone surveying takes it to a whole new level by not only producing individual points but also taking thousands of measurements in just a single drone flight.

This information can also be rendered not only as an as built 3D BIM model but also as contour lines, DTM and orthomosaic formats.

• It cuts down survey costs and field time.

Using a drone in capturing data is actually five times faster than conventional survey methods using a traditional 3D laser scanner.

It means that you can cut down survey costs significantly and reduce the number of people and resources that’s needed just to complete a survey for a construction project.

Drone surveying also has a PPK geo-tagging feature, which helps speed up the surveying process by eliminating the need to place numerous GCPs that could take a lot of time and manpower to do.

• It can easily get to hard-to-reach locations.

With a drone, you don’t need to worry about any physical limitations when it comes to taking measurements because you’re capturing data from above. Drones can also take off and fly almost anywhere, so you don’t need to think about going through rough terrain or disrupt traffic just to survey an area.

In fact, it only takes a few people to operate a drone and render data into as built 2D AutoCAD drawings unlike doing a traditional survey that requires a lot of people and equipment to complete.

With the power to take measurements from a completely different perspective and capturing data from various angles within just one sweep, drone surveying is set to redefine the 3D laser scanning market and costs over the next few years.

Drone surveying is especially beneficial in generating high-resolution data for land surveying or cartography that allows for engineers and architects to create easier cadastral mapping even in the most difficult environments.

Drones can even capture minute details like fire hydrants, curbs and road markers. Drone surveying is also useful for generating images of massive land areas for proper land management and planning for construction of roads and infrastructure.

We can also look forward to more industries embracing this unique surveying method that utilises the best of what technology has to offer.
