Because Every Kilometre Matters
MANAGING LINEAR INFRASTRUCTURE
WITH CONFIDENCE & PRECISION
The performance of road and rail networks depends on accurate, consistent and regularly updated infrastructure data.
Without reliable information, decision-making slows, operational risks increase and maintenance costs escalate.
The Geoliance Group combines advanced multi-sensor acquisition technologies, including ground-penetrating radar (GPR), mobile and airborne LiDAR, and ultra-high-resolution imagery, to deliver a complete 3D understanding of transportation assets, their surrounding environment and the risks that affect them.

ROADS : UNDERSTAND
ANALYSE, ANTICIPATE
Our surveying and mapping solutions rapidly cover extensive road networks without disrupting traffic operations.
We help infrastructure managers:
- Create detailed 3D models of road assets and their surrounding environment
- Inspect and monitor bridges and engineering structures
- Locate underground utilities and buried infrastructure
- Identify obstacles, encroachments and potential conflict zones
But also :
- Produce highly accurate topographic surveys of road corridors
- Monitor ground movement, subsidence, erosion and geotechnical instability
- Inventory signs, road furniture and traffic management assets
- Support route planning, redesign projects and as-built surveys
- Assist construction teams with surveys, verification and setting-out operations
From project planning to long-term asset management, our solutions provide a clear and shared understanding of road infrastructure.
RAIL: SAFETY,
COMPLIANCE, PERFORMANCE
Our technologies enable detailed and continuous analysis of railway infrastructure and corridors.
Applications include:
- Regulatory clearance and loading gauge analysis
- Ballast conformity assessments
- Safety distance measurements for catenary systems, platforms and infrastructure
- Vegetation analysis and encroachment detection
Mais aussi :
- 3D modelling of railway tracks and surrounding assets
- Monitoring of bridges, tunnels, embankments and earthworks
- Ground movement and stability monitoring
- Track condition assessment and rehabilitation support
- New route and infrastructure studies
Objective : improve safety, reduce emergency interventions and enhance network reliability.
Project Examples
Road Asset Inventory & Infrastructure Management
Challenge
Building and maintaining a comprehensive inventory across tens or hundreds of kilometres can place significant demands on field teams.
The Geoliance Solution
Mobile LiDAR systems rapidly capture extensive road corridors without disrupting traffic, while all data is integrated into a consistent GIS asset management platform.
Results
- A complete and consistent view of the network
- Faster data updates
- Improved maintenance planning and budget forecasting
