Survey instruments

A full set of modern surveying instruments, from GNSS receivers to survey drones and sonar boats. We pick the method that fits the site, then check the result against control.

GNSS receivers

Trimble R4 and R10 GNSS

  • Accurate mapping of land elevation and topography, with outputs ready for CAD.
  • GPS and GNSS receivers that keep reliable data in hard field conditions.

Robotic total stations

Trimble and Sokkia total stations

  • Automated stations for very accurate angle and distance measurements.
  • Used for construction, site layout, boundary determination and monitoring.

3D scanning and LiDAR

Terrestrial scanners and mobile LiDAR

  • Capture millions of data points in real time for complex modelling, building information and volume analysis.
  • Mobile LiDAR for rapid 3D mapping, indoors and outdoors.

Survey drones

Drone fleet

  • High-resolution aerial mapping, orthophotos and photogrammetry.
  • Reach hard-to-access places safely and quickly.
