Where’s the job?

Overview

• Aerial mapping of construction sites uses drones fitted with high-resolution cameras and sensors to capture detailed images and LiDAR data.

• Skill level: 3 / 5 (requires technical drone handling, planning flight paths and data processing know-how).

• Typical duration: 1 – 2 days for data capture, with additional time for processing and analysis.

Safety First

• Always adhere to local drone regulations and airspace restrictions prior to any flight.

• Conduct comprehensive pre-flight checks, including weather conditions and equipment functionality.

• Maintain visual line-of-sight or secure necessary permissions for extended visual operations.

• Use certified and insured drone operators to mitigate risks and ensure compliance.

Tools & Materials

Step-by-Step

1. Plan the flight path – define the survey area, altitude, overlap and speed to ensure comprehensive coverage.

2. Calibrate the drone and sensors – perform system checks, battery tests and ensure proper GPS synchronisation.

3. Execute the flight – conduct multiple passes, ensuring sufficient overlap between images for accurate stitching.

4. Collect data – capture high-resolution images or LiDAR points and record geotagged metadata.

5. Process the data – use mapping software to generate orthophoto maps and 3D models from the captured data.

6. Analyse and validate – review the maps for accuracy, ensuring all required details are captured; re-fly if necessary.

7. Deliver the results – finalise and share the processed maps and 3D models with the project team.

Completion Checks

• Generated maps and models accurately represent the construction site with verified georeferencing.

• Data integrity is confirmed using ground control points and software validation.

• All regulatory and project standards have been met prior to final handover.

When to Call a Pro Instead

For projects requiring certified geospatial accuracy, strict regulatory compliance or specialised data analysis, engaging professional drone surveyors ensures optimal results and mitigates liability risks.
