Airborne LiDAR

Aircraft-mounted laser scanning for dense, georeferenced and classified 3D point clouds.

// Overview

Airborne LiDAR

In airborne LiDAR, an aircraft-mounted laser scanner samples the earth surface with hundreds of thousands of pulses per second. The result is a dense, georeferenced 3D point cloud – the basis for terrain models and for vegetation and infrastructure analysis. Unlike pure photogrammetry, LiDAR penetrates vegetation and delivers reliable ground points even beneath tree canopies. That makes it particularly suited to forestry, flood protection, corridor planning and large-area as-built documentation.

// Data products

Georeferenced point cloud

A raw, accurately positioned 3D point cloud (LAS/LAZ) with intensity values – the unprocessed measurement basis for your own evaluations.

Classified point cloud

A point cloud classified into ground, vegetation, buildings and infrastructure – ready to use for DTM, DSM and derived analyses.

// Georeferenced point cloud

Georeferenced point cloud

Airborne laser scanning (ALS) produces high-precision 3D point clouds for surveying, planning, BIM and as-built documentation. Individually adjustable point densities yield detailed digital representations of cities, municipalities and infrastructure and corridor projects.

// Classified point cloud

Classified point cloud

Point cloud classification assigns measured points to surface and object classes, automatically or manually. The result is structured datasets that serve as the basis for terrain models, analyses and further geospatial products in surveying and planning.

// Process

From the survey flight to the point cloud

01
Flight planning
Planning flight lines, point density and overlap to suit the area and the target accuracy.
02
Survey flight
Data capture with a calibrated laser scanner and GNSS/IMU trajectory under suitable conditions.
03
Georeferencing & strip adjustment
Trajectory computation, strip adjustment and positional control against ground control points for maximum accuracy.
04
Classification & delivery
Automated and manually reviewed classification, quality control and handover in your target format.
