Understanding Stockpiles, Quarries and Client Needs: The Dee4Drones Journey


Stockpiles aren't just piles of material.
They're assets. Inventory. Money sitting on the ground.
When Yorkshire businesses trust me to measure these assets, they're not just getting drone pictures. They're getting precision calculations that directly impact their bottom line.
My journey to becoming Yorkshire's trusted stockpile calculation expert didn't happen overnight. It took more than a decade of experience, continuous learning, and a relentless focus on client results.
The Foundation of Expert Service
Building Dee4Drones into what it is today required several critical foundations:
- Professional Qualifications: Passing rigorous CAA Drone examinations to ensure complete compliance and safety standards
- Technology Investment: Carefully selecting drone equipment specifically designed for quarry and stockpile work
- Software Expertise: Mastering specialised calculation software with reliable technical support
- Results Delivery: Developing systems to provide clients with accurate, actionable data they can trust
After 10+ years working in quarries across Yorkshire, I've built not just a business, but a "stockpile" of returning customers who rely on our expertise.
Real-World Challenges That Make the Difference
What separates Dee4Drones from generic drone services? The ability to handle complex real-world situations that affect measurement accuracy.
Every quarry presents unique challenges:
- Uneven Ground: Requires specialised calculation approaches
- Overhanging Foliage: Demands strategic flight planning to ensure complete coverage
- Concrete Block Holdings: Needs precise marker placement for accurate volumetric calculations
- Elongated Stockpiles: Benefits from specialised triangulated measurement settings
- Overlapping Materials: Requires experienced analysis to differentiate between materials
These challenges appear across different sites, and understanding them is essential for delivering accurate results that clients can rely on for business decisions.
Stockpile Calculation Methods: The Technical Expertise
Linear Fit Calculations
The simplest scenario involves stockpiles on completely flat ground, whether in quarries, quayside locations, construction sites or farmyards.
Linear Fit calculations create a flat plane through the edge points marked around a stockpile. This method is ideal for standalone materials sitting on uniform surfaces, as it minimises discrepancy issues when calculating volume.
However, even in these straightforward scenarios, converting volume to mass requires precise density knowledge, a detail many less experienced operators overlook.
Lowest Point Calculations
When stockpiles sit on uneven ground (a common scenario), the calculation approach must change. Our process involves:
- Strategic dot marker placement around the stockpile perimeter
- Setting the software to "Lowest Point" calculation mode
- Leveraging the 210ft autonomous drone flight data to capture all terrain variations
This methodology applies equally to stockpiles housed in concrete block clamps, where marker positioning becomes even more critical for accuracy. The Lowest Point setting is essential when you can't measure the back of a stockpile, such as when it's against a wall or contained in bunkers.
Triangulated Measurements
Long, narrow stockpiles (such as those alongside buildings or adjacent to other materials) require a completely different approach using triangulated settings. Using the wrong calculation method here can significantly impact the final mass calculation - a mistake inexperienced operators often make.
Triangulated calculations are specifically designed for elongated stockpiles where standard measurement techniques would produce inaccurate results. This method ensures the volume calculation accounts for the unique shape characteristics of linear material deposits.
Beyond Basic Measurements
Our expertise extends beyond simple stockpile calculations to include:
- Land level assessments
- Area measurements
- Pile height determinations
- Fill level calculations for excavated areas
Each requires specific expertise to deliver accurate results.
The Customer Service Difference
Technical capability means little without customer focus. Over my decade-plus in this industry, I've built lasting relationships with quarry operators, construction companies and aggregate suppliers across Yorkshire.
They return because they know I understand their business needs, not just drone technology. They trust our calculations for inventory management, production planning and financial reporting.
Looking Forward
As Yorkshire businesses continue facing economic challenges, precise stockpile management becomes even more critical. Having accurate data on material assets allows for better cash flow management, production planning, and operational efficiency.
With over a decade of specialised experience, CAA qualifications, and a deep understanding of the unique challenges of stockpile measurement, Dee4Drones remains committed to delivering the accuracy Yorkshire businesses depend on.
