At Chatterley Valley, weekly drone surveys helped turn a large and complex earthworks project into clear, measurable site data.
More than 20 ground control points were used across the site to strengthen positional accuracy and support consistent survey results across the project timeline.
Each survey captured thousands of images, which were then processed into useful outputs for review and analysis.
Typical weekly survey outputs included:
- High-resolution orthomosaics for a clear visual record of the site
- Point clouds to help review site shape and surface detail
- Digital elevation models to support earthworks analysis
- Volume calculations for monitoring material movement
- Progress imagery for communication and project records

Turning Aerial Data Into Earthworks Insight
The drone imagery was processed into mapping and modelling outputs, including orthomosaics, point clouds and elevation data. These outputs made it easier to review progress across the full site and to support more detailed earthworks calculations.
The site was also divided into 50 m x 50 m grid areas for detailed material movement analysis. This made the data easier to manage, compare and use as part of the wider project workflow.
Instead of relying on scattered ground-level information, the project team had a consistent aerial record of site change over time.
Why Weekly Drone Surveys Helped
1. Faster site capture
Each drone survey took around 1.5 hours to capture. For a large site, that provides a fast way to record current conditions and reduce the time needed to collect visual data from the ground.
2. Safer working
Drone capture reduced the need for surveyors to walk across active earthworks areas, helping keep people away from machinery, uneven ground and other site hazards.
3. Clearer progress records
Weekly aerial outputs created a visual timeline of the project. This helped show what had changed, where work had progressed and how the site developed over time.
4. Better communication
Orthomosaics and aerial visuals gave teams a shared reference point. That makes it easier to discuss locations, progress, access routes and areas of interest during meetings or project reviews.
5. Useful data for earthworks analysis
Point clouds, elevation models and volume calculations supported more detailed analysis of site levels and material movement.
What This Means for Construction and Earthworks Projects
Drone surveys are not just about attractive aerial images. On large and changing sites, they can provide practical information that helps teams understand the project more clearly.
For construction, civil engineering and earthworks projects, regular drone surveys can support:
- site progress tracking
- earthworks monitoring
- volume calculations
- project reporting
- stakeholder updates
- visual evidence of completed work
- safer data capture on active sites
If your project team needs a clear visual record of a site, our drone survey services can help you choose the right output.
