Railways

LiDAR corridor mapping solutions for railways

Custom LiDAR & photo acquisition services and data processing for the maintenance, construction and analysis of railway infrastructure

Flexible data capture

Non-invasive aerial LiDAR & imagery data for digital twin generation

Exclusive data capture techniques, cutting-edge technologies and know-how for efficient & custom LiDAR surveys and inspections

Non-invasive

Acquisition by helicopter, plane or drone depending on project dimension

Simultaneous

Simultaneous acquisition of all needed data in a single flight, including nadir and oblique views of the infrastructure

High density and accuracy

Our technology allows us to capture LiDAR point clouds with a density up to 1'000+ pts/m2 in a single pass and 1 cm accuracy

High-res imagery

For image-based mapping and inspection: Nadir and oblique views, thermal, near-infrared (NIR), 360° and more

Mobile mapping surveys

Rail-based LiDAR & imagery surveys

Complementary rail-based LiDAR & imagery acquisition to capture structures and tunnels

Custom made

Our adaptive system can fit any railway network without compromising quality

360° images

Very high-resolution georeferenced 360° images to capture every detail even under infrastructure and in tunnels

High density and accuracy

Our technology allows us to capture LiDAR data with a point cloud density of 2'000+ pts/m2 and up to 1 cm accuracy

Gaps-free data set

Thanks to the unique combination of Airborne (ALS) and Mobile Laser Scanning (MLS) from a single provider & in the same workflow

Custom products

A broad spectrum of data products

In a single pass, a variety of data is collected simultaneously and processed into specific data products. Delivery in the format of choice and platform-independent visualization via web viewer.

LiDAR

Classified LiDAR point clouds and Digital Terrain Models

Maps

2D & 3D topographic maps and object digitization

Models

3D photorealistic models, BIM and visualizations

Imagery

Ortho/oblique imagery and visual/IR inspection reports

Network maintenance

Vegetation, ballast, infrastructure and hazards monitoring

From the reactive approach to data-driven maintenance: Regular surveys help detect, monitor and control hazardous vegetation and other anomalies at an early stage to ensure proper functioning of the network. Our data offers the perfect level of detail to perform all these analyses.

Vegetation Control

LiDAR acquisition and imagery optimized for vegetation monitoring

Ballast monitoring

High precision and high resolution data for ballast monitoring

Inspection of infrastructure

Providing data for visual inspection of assets and infrastructure

Natural hazards monitoring

Improved safety by monitoring natural hazards

Management and design

Asset management, new line design and optimization

Our as-built models support decision-making at any stage in the entire lifecycle

Planning & design

Fundamental topographic data and models to plan and design new lines

Simulation

Energy efficiency, environment, risks and photorealistic visualization of scenarios

Complete BIM integration

BIM integration for effective asset management

Collaborative environments

Working together across space, time and organizational boundaries
