Mapping & Surveying is the process of creating a highly accurate 3D digital version of the worksite you’re on…. think of it as a digital twin.  This is through a process called Photogrammetry. This is the process of collecting physical information from two-dimensional aerial images. By combining overlapping, geotagged images of the same features from different angles, photogrammetry software such as Pix4D generates photorealistic 3D representations of worksites.

More and more industries are incorporating the use of drones, (UAVs), into their projects. At the forefront of this is the survey and construction sectors who have optimised labour and streamlined cost by implementing drones into their operations.

Having a drone mapping solution allows for autonomous flights and eliminates several risks associated with land surveying.

The advantages of digital photogrammetry is that its a quick and cost-effective form of data collection. This provides an actual and permanent photographic record. Aerial photogammerty also allows data acquisition to be done without disrupting operations on the ground and analysis can be performed from the office rather than in the field.

What are the Advantages of Drone Mapping & Surveying?

Increased Efficiency, Lower Costs: 

Drone flights can take as little as 10-15 minutes and access all areas that would be hard & potentially dangerous to reach on foot. This makes the end-to-end cost of a drone flight significantly lower than traditional survey methods. As well as this, using a drone allows maximal awareness of the progress on site, if a team needs another part of the project to be done before they can carry out their work, a drone can help to ensure the team is kept In the loop to make sure they do not turn up to site early, allowing them to spend their time more efficiently elsewhere.

Precision Accuracy:  

Because drone maps contain thousands of points, compared to the few
hundred points obtained through traditional survey methods, maps with relative accuracy give a highly detailed overview
of terrain that works well for these types of projects. 

All in one tool:  

Drone mapping allows a level of highly detailed data collection across a large area that isn’t possible through satellite images or traditional ground surveying. You can then process the data using photogrammetry software such as Pix4D generates photorealistic 3D representations of worksites. This makes using a UAV a “one-stop” mapping & surveying solution.
