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.

What is Drone Mapping?

Drone mapping creates 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 captured by drones. By combining overlapping, geotagged images of the same features from different angles, photogrammetry software such as Pix4D generates photorealistic 3D representations of worksites.

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 can Drone Mapping be used for in an ongoing project?

Track Progress: Flying a drone over your project at various intervals will allow you to track progress quickly and easily. This means you have a record of your project at every stage of development; allowing you to give more detailed information back to the client/project lead on progress and formulate more realistic predictions for the timeframe to complete the remaining work.

Aid Accuracy In Plans: Every large-scale project needs a coherent plan in place to ensure all involved know what the operation consists of. Whether this be
day-to-day planning, or architectural plans on construction sites, having a
virtual photorealistic 3D twin of your site can aid these plans.

Streamline Labour: 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.

Reduce Time & Cost of Surveying/Planning: Drone flights can take as little as 10-15 minutes and access all areas that would be hard to reach on foot. This makes the end-to-end cost of a drone flight significantly lower than traditional survey methods.

 

How can Drones be used across different Industries?

Mining & Aggregates: Large Mining Sites and Quarries can be notoriously dangerous and have multiple “difficult to reach” areas. Flying a drone high above the site alleviates the human risk within this and aid in project planning and assessment.

Waste Management: Using a drone in waste management can allow you to survey how effectively your site is being used, thus boosting efficiency. It can also allow you to perform quick and accurate calculations of compaction densities and remaining airspace.

Waste Management: Drones can be used to monitor the progress of building projects ad allow more efficient planning as the project advances. This will help minimise the money spent on the project and ensure more accurate deadlines. Drones can also be used the planning stage as modern technology allows sub 1cm accuracy so construction professionals can plan how their site will be set out using accurate dimensions.
