Our specialty
Rail Geometry Survey
Our Rail Geometry Survey service combines GNSS positioning, robotic total stations and track measurement trolleys to collect accurate track geometry data. We analyze critical parameters — alignment, cant, curvature, vertical profile and gauge — to catch deviations before they become safety risks.
Alignment
Horizontal line
Cant
Rail superelevation
Curvature
Curve radii
Gauge
Distance between rails
Vertical profile
Longitudinal level
Result
A safe, compliant network
In the air
Advanced Drone Pilot Services
Our advanced drone pilot services deliver high-resolution aerial imagery and complete site data. Ideal for quickly covering large areas — rail corridors, construction sites, structures — without putting crews at risk.
- Photogrammetry and georeferenced orthophotos
- Point clouds and 3D models
- Volume calculations and site progress tracking
- Corridor and structure inspection
- Advanced drone operations
- Fast data delivery
