Drone-based aerial survey for very large outdoor yards and hard-to-reach pile geometries. High-resolution photogrammetry, RTK-georeferenced — typically a 30-minute flight for a 5-hectare yard, delivered as orthophoto, DTM, DSM, 3D mesh and per-pile volumes.
For yards larger than 1 hectare, ground-based scanning becomes slow and blind-spot-prone. Our drone-survey service uses a heavy-lift drone with an RTK-georeferenced 1-inch-sensor camera capturing the yard photogrammetrically. Processing delivers volume calculation and mass estimation per pile — a complete volumetric stockpile survey from the air.
A single 30-minute drone survey flight covers 5 hectares at 2 cm ground sample distance. You receive orthophoto, DTM (terrain), DSM (surface), 3D mesh, contour plan and per-pile volumes — within three business days. We offer drone surveying across the entire DACH region — several bases and local pilots keep travel costs and response times low. For sites that need inventory figures for same-day decisions rather than for the accounts, continuous stockpile monitoring with stationary LiDAR is usually the better fit.
Used at Aurubis copper smelter, port-side aggregate yards and quarry mountain faces.
Heavy-lift drone covers 5 hectares in a single 30-minute flight. No ground access needed.
RTK GNSS + ground-control points = 2 cm absolute precision. Orthophoto + DTM in same coordinate system.
RTK GNSS plus ground control points georeference every flight to 2 cm absolute — survey grade, not an estimate.
Day 1: site visit, GCP placement, drone flight (~30 min). Day 2-3: registration, georeferencing, orthophoto + DTM/DSM generation, per-pile volumes. Delivery in your inbox by end of day 3.
Aerial survey is the right call when ground access is restricted or yard size exceeds 1 ha.
Aerial survey delivers what ground-based scanning can't: top-down geometry of every pile, regardless of access. Need 24/7 instead of one-off? See LiDAR vs drone for stationary monitoring.
Industrial drone payload, RTK-corrected positioning. 2 cm absolute precision in client coordinate system.
High-overlap image flights, RTK georeferencing, ground-control checks — dense point cloud, orthophoto and DTM from a single flight.
From flight to inbox in three business days. Orthophoto, DTM, DSM, mesh, per-pile volumes.
Our pilots hold A1/A3 + STS-01 EU drone licenses. Insurance and permits handled end-to-end.
Several bases across Germany, Austria and Switzerland — the pilot from your region flies the mission. Short travel, low travel costs, fast scheduling.
Our EU-licensed pilots on real client sites: sand quarries, coal yards, industrial campuses. RTK positioning, planned flight grids, repeatable missions.
Drone surveying is more than aerial photos — every flight delivers defensible numbers for inventory, billing and planning.
Per-pile volumes at ±2 % — mass via bulk density, audit-grade for inventory and billing. Includes landfill cubage and recycling stock.
The complete extraction site as a terrain model: overburden cubage, quarry faces, terrain profiles and as-planned vs. as-built comparison — without setting foot on a wall.
Roads, conveyor routes, utility corridors and embankments as longitudinal and cross profiles — the basis for earthworks tenders and mass calculations.
Building heights, roof and facade areas determined photogrammetrically — for as-built documentation, planning and clearance evidence.
Digital terrain model (DTM) and surface model (DSM) per construction stage: progress documentation, earth-mass balance and as-planned vs. as-built weekly.
We fly from the region, not from one headquarters: bases in Kiel, Stade, Krefeld, Bad Lauterberg, the Ore Mountains, Geretsried and the Black Forest keep travel short.

Price, accuracy, process — the questions that come before commissioning a drone survey.
