Quarry & Stockpile Measurement
Aerial photogrammetry provides a fast, repeatable method for documenting stockpiles, material inventories, quarry areas, and changing surfaces while creating a permanent spatial record of each measurement.
Measure Material Without Walking Every Pile
Traditional stockpile measurement can be time-consuming and difficult around steep, unstable, or active material areas. Aerial mapping captures the visible surface of the stockpile from above and around its perimeter, allowing the resulting 3D surface to be measured digitally.
The same workflow can be repeated throughout the year, providing both individual volume measurements and a historical record of changing material inventory.
Typical Applications
- Aggregate stockpiles
- Soil and fill material
- Sand and gravel
- Quarry materials
- Construction material inventory
- Recurring stockpile tracking
- Surface comparison
- Selected cut-and-fill analysis
From Aerial Capture to Material Quantity
The stockpile measurement is only one output from the mapping dataset. The same capture can provide site context, 3D visualization, and a permanent record of conditions at the time of measurement.
Stockpile Volumes
Individual piles can be defined and measured against an appropriate base surface to calculate material volume.
3D Surface Models
Photogrammetric processing creates detailed three-dimensional surface models of stockpiles, quarry areas, terrain, and surrounding conditions.
Inventory Documentation
Dated mapping records provide visual and measurable documentation of material inventory at a specific point in time.
Recurring Measurements
Repeat aerial capture can establish a consistent process for monthly, quarterly, milestone-based, or other scheduled inventory measurements.
Site Visualization
Orthomosaics and 3D models provide context around material locations, access routes, operating areas, and overall site conditions.
Surface Comparison
Mapping datasets collected at different times can support evaluation of selected surface changes and material movement across the site.
Why the Base Surface Matters
A stockpile volume is calculated between the visible surface of the material and an estimated or defined base surface beneath the pile. Selecting the correct base is therefore an important part of the measurement workflow.
Depending on site conditions, the base may be represented by surrounding terrain, a defined plane, previously captured ground conditions, or another appropriate surface model.
- Stockpile boundary definition
- Base-surface selection
- 3D surface calculation
- Volume reporting
- Visual verification
- Historical comparison
Repeatability Is the Bigger Advantage
A single inventory measurement is useful. A consistent series of measurements creates operational history. Using repeatable aerial capture gives site teams a comparable record of material quantities, pile locations, and changing site conditions over time.
Stockpile Measurement Workflow
Define the Area
Identify stockpiles, material areas, required outputs, positioning requirements, and site access.
Map the Site
Collect overlapping aerial imagery across and around the material using a planned mapping workflow.
Build the Surface
Process the imagery into an orthomosaic, point cloud, 3D surface model, and measurement environment.
Calculate & Document
Define stockpile boundaries and base surfaces, calculate volumes, and provide the requested measurement record.
Applications Beyond a Single Stockpile
Quarries & Aggregate Operations
Document aggregate inventory, material locations, active areas, and site conditions using repeatable aerial measurement.
Construction Sites
Track imported or excavated material, temporary piles, fill, spoil areas, and selected earthwork quantities.
Material Suppliers
Create recurring inventory records across storage yards without relying solely on manual field measurement.
Site Development
Combine material measurements with broader mapping, terrain models, and changing-site documentation.
Available Deliverables
Volume Reports
Documented stockpile quantities with project-specific measurement information and supporting imagery.
Orthomosaic & 3D Model
Visual mapping products provide context for the measured stockpiles and the surrounding site.
Technical Data
Point clouds, surface models, elevation data, and other project-specific exports can be provided when required.
