Topographical LiDAR

Drone-mounted LiDAR systems emit laser pulses and measure their return to generate dense and accurate 3D point clouds of terrain and surface features.

A key advantage is the ability to capture multiple returns from a single laser pulse, allowing separation of:

• Ground surface
• Vegetation layers
• Buildings and infrastructure

This makes LiDAR the preferred solution in environments where optical mapping methods are limited.

Typical applications include:

• Digital Terrain Models (DTM) and contour generation
• Infrastructure and road planning
• Flood risk and hydrological analysis
• Forestry and vegetation mapping
• Corridor mapping for roads, railways, and powerlines
• Volume calculations and earthworks
• Base datasets for GIS, CAD, and BIM workflows

FROST operates professional LiDAR systems integrated with high-precision GNSS and IMU positioning.

Each mission is adapted to:

• Terrain complexity
• Vegetation density
• Required accuracy level

FROST operates professional LiDAR systems integrated with high-precision GNSS and IMU positioning.

This ensures:

• High point density and consistent coverage
• Accurate horizontal and vertical positioning
• Reliable ground classification, even in dense vegetation

LiDAR datasets can also be combined with RGB imagery and orthophotos for enhanced visualization and analysis.

We provide industry-standard datasets ready for direct integration into professional workflows, including:

• Classified and unclassified point clouds (LAS / LAZ)
• Digital Terrain Models (DTM)
• Digital Surface Models (DSM)
• Contours and elevation datasets
• GIS- and CAD-ready files
• Optional integration with orthophotos and 3D models
