The Technology Behind the Accuracy

We combine RTK-enabled drone hardware with advanced photogrammetry software to deliver audit-grade volumetric measurements you can trust.

How We Measure Your Inventory

1
RTK Precision GPS
Our drones utilize Real-Time Kinematic positioning, achieving centimeter-level accuracy. Ground control points and RTK corrections ensure your volume calculations are tied to real-world coordinates.
2
Photogrammetric Capture
We capture hundreds of overlapping aerial images at precisely calculated intervals. Each image is geotagged with high-accuracy position data for seamless reconstruction.
3
3D Point Cloud Processing
Advanced photogrammetry software processes the imagery into dense 3D point clouds. Each stockpile is reconstructed with millions of measurement points for maximum accuracy.
4
Deliverable Reports
You receive professional PDF reports with volumetric calculations, orthomosaic maps showing your site from above, and optional CAD-compatible files for integration with your systems.

Why 1-3% Accuracy Matters

Traditional Methods

  • 8-15%Typical error with GPS rovers and manual tape measures
  • HoursRequired to walk each pile with safety risks
  • SubjectiveResults vary by operator and conditions

Our Photogrammetry Approach

  • 1-3%Consistent accuracy with RTK-enabled equipment
  • MinutesFlight time with zero crew exposure on piles
  • RepeatableConsistent methodology produces comparable results

Terminology Glossary

Photogrammetry
The science of making measurements from photographs. By analyzing multiple overlapping images taken from different angles, we can reconstruct accurate 3D models of your stockpiles.
RTK (Real-Time Kinematic)
A satellite navigation technique that provides centimeter-level positioning accuracy. RTK uses a fixed base station and mobile receiver to correct GPS signals in real-time.
Orthomosaic Map
A geometrically corrected aerial image that combines hundreds of individual photos into a single, accurate, measurable map of your site. Every pixel is geo-referenced.
Point Cloud
A set of 3D data points representing the external surface of your stockpiles. Our point clouds contain millions of measurements, enabling precise volume calculations.
Cut/Fill Analysis
A comparison between two surveys taken at different times, showing exactly how much material was added (fill) or removed (cut) from each stockpile.
Digital Twin
A digital replica of your physical site that can be measured, analyzed, and compared over time. Your inventory history becomes a searchable, auditable digital asset.
