Accurate Volumes and Earth Masses with Drones

Volume calculation from drone surveys provides a centimeter-accurate picture of earth masses, stockpiles, and cut & fill volumes. We use an RTK GNSS-equipped drone and ground-measured control points for absolute accuracy. With repeated measurements, you can track how much material has moved and how much remains — throughout the project.

Benefits of the Service

Measurement-Accurate Quantities. RTK GNSS accuracy and ground control points ensure centimeter-level accuracy. Precise figures help avoid over- and underestimates.

Controlled Material Flow. Quantities based on measured data allow precise planning of transports and material use.

Verifiable Figures. Georeferenced, documented data for contract calculations, invoicing, and quantity verification.

Regular Monitoring. Repeated measurements document changes in earth masses precisely.

Volume Calculation or Mass Calculation?

Volume calculation indicates cubic meters of material — stockpile volumes or cut & fill quantities. This is the core of our service.

Mass calculation (tonnage) is obtained when volume is multiplied by the material's density factor. We produce mass reports when you provide the density factors for your materials.

What Volume Calculation Is Used For

• Volume measurement and stock monitoring of stockpiles (soil, crushed aggregate, recycled materials)
• Calculation of cut & fill volumes
• Verification of earthworks and foundation levels before casting
• Monitoring of quarrying and excavation volumes
• Basis for contract calculations and invoicing

Who the Service Is For

Earthworks Companies and Contractors. Plan transports based on precise quantities and verify completed work.

Mining and Aggregate Operators. Track stockpile quantities for purchasing, sales, and processing decisions.

Construction Companies. Ensure earth masses are in the right place on schedule.

Municipalities and Clients. Monitor contract progress and verify invoicing against measured quantities.

Part of a Bigger Picture

Volume calculation uses the same drone survey as construction site mapping and orthophotos. The precise elevation models can also produce 3D models.

What We Deliver

• Volume report — stockpile volumes and cut & fill in cubic meters
• Mass report when needed — tonnage calculated using material density factors
• Digital Surface Model (DSM) and georeferenced orthomosaic
• Time series — material changes documented over time
• Data in the coordinate system of your choice — ETRS-TM35FIN, EUREF-FIN, or other

Frequently Asked Questions

What's the difference between volume calculation and mass calculation? Volume gives cubic meters; mass converts to tonnes using density factors — we produce it once you provide the factors.

How accurate are the results? Centimeter-level accuracy from the RTK GNSS drone and ground control points.

Are ground control points needed? Always, when quantities need to be verifiable.

How often should measurements be taken? Recurring measurements (weekly) give the best picture of progress. One-time suits a specific status snapshot.

Can old and new measurements be compared? Yes — consecutive measurements show how much material has moved.
