Our technology

The Helimap System® – Precision LiDAR and Photogrammetry from Above

Developed with EPFL’s photogrammetry and topometry labs, our airborne and vehicle-based systems combine LiDAR and digital photogrammetry to deliver accurate, reliable data — even in the most difficult terrains.

Our sensors are designed for both airborne and mobile mapping, made from the integration of different state-of-the-art high-tech components

  • PhaseOne high-resolution digital cameras (50 Mpix to 150 Mpix)
  • NIR (Near Infrared) cameras (100 Mpix to 150 Mpix)
  • Oblique cameras (24 Mpix to 100 Mpix)
  • 360° panoramic camera
  • Thermal camera Flir
  • Riegl laser scanners (up to 2’000’000 points/sec)

Additional customizable sensors as per project requirements

HS1 marked our first complete airborne LiDAR system. It introduced a lightweight platform for capturing topographic data with single-echo technology, opening the way for faster and more accurate mapping workflows.

HS2 introduced multi-echo LiDAR integration, enabling the detection of multiple returns per pulse. This upgrade improved ground penetration in forested areas and generated richer datasets for terrain modeling.

The SAM mobile mapping solution combined high-precision LiDAR with GNSS-INS positioning to capture detailed 3D data directly from ground vehicles. It provided efficient corridor mapping for roads, railways, and urban environments.

HS4 represented a major system refinement, offering improved stability, enhanced scanning performance, and an optimized workflow for airborne survey missions. It became a reliable platform for medium-scale mapping projects.

HS5 was engineered to be our lightest airborne LiDAR system to date. Its compact design made it ideal for UAV-based operations while preserving precision and high-density point capture.

V3 was developed for long-range LiDAR applications, allowing the efficient mapping of large surfaces and complex terrains. Its extended range made it suitable for wide-area topographic and environmental monitoring.

HS6 and HS7 introduced very high-density LiDAR acquisition, offering unprecedented point cloud resolution. These systems improved detail extraction for engineering, infrastructure inspection, and urban 3D modeling.

HS8 introduced the Nadir-Forward-Backward configuration, achieving complete scene coverage with minimal occlusions. Its multi-directional scanning architecture delivers superior accuracy for advanced mapping missions.
