Why Drone Surveys?

Traditional methods vs modern drone-based measurement

Traditional Methods

  • Manual tape/wheel measurements take days
  • Total station surveys are slow and expensive
  • 10-20% estimation errors common
  • Safety risks walking on unstable piles
  • Limited to accessible pile surfaces only

Drone Survey Advantage

  • Survey entire stockyard in 2-4 hours
  • Millions of measurement points captured
  • 99% accuracy with RTK positioning
  • No personnel on stockpiles - completely safe
  • Complete 3D surface capture from above

Two Technologies

We select the right approach based on your site conditions and requirements

RGB Photogrammetry

  • High-resolution camera captures overlapping images
  • Software reconstructs 3D surface from photos
  • Best for open, well-lit stockyards
  • Cost-effective for most applications
  • 1-3cm horizontal, 2-5cm vertical accuracy

LiDAR Drone Survey

  • Laser pulses measure distances directly
  • Works in any lighting condition
  • Penetrates vegetation and shadows
  • Best for complex terrain and mixed materials
  • 3-5cm vertical accuracy, no GCPs needed

Survey-Grade Equipment

We use enterprise-grade drones with RTK/PPK positioning for centimeter-level accuracy on every survey.

RTK/PPK Positioning

Real-Time Kinematic GPS delivers centimeter-level positioning accuracy on every image capture

High-Resolution Cameras

45+ megapixel sensors capture fine surface details for accurate 3D reconstruction

LiDAR Sensors

300,000+ pulses per second for dense point clouds in challenging conditions

DGCA Compliant

All operations follow DGCA regulations with certified remote pilots and equipment

Outdoor Stockpile Applications

From mining pits to port terminals - accurate measurement for any open stockyard

Mining Stockyards

Coal, iron ore, bauxite, and mineral stockpiles at mine sites - ROM pads, crushing plants, and dispatch yards

Most Common

Cement Plant Yards

Limestone, clay, gypsum, and fuel stockpiles - pre-homogenization yards and raw material storage

Port Terminals

Bulk cargo stockpiles at ports - import/export yards, berth-side storage, and transit stockyards

Quarries & Crushers

Aggregate, sand, gravel, and crushed stone stockpiles at quarry sites and crushing plants

Not an Open Stockyard?

We have solutions for every environment

Indoor / Covered Stockpiles?

Warehouses, sheds, silos, and covered stockyards where drones can't fly overhead. We use terrestrial LiDAR and SLAM-based scanning for accurate measurement inside enclosed spaces.

Site in a No-Fly Zone?

Near airports, military areas, or restricted airspace? No problem. We use ground-based survey methods including terrestrial LiDAR, total stations, and SLAM scanners - no drone required.
