Railway topographic surveys with drones, LiDAR, and point clouds
A reliable railway project starts with an accurate survey. P-WAY Engineering performs planimetric and altimetric surveys of stations, tracks, and private connections using total stations, GPS, drones, and LiDAR sensors, producing high-density point clouds and digital twins of the infrastructure. Accurate, georeferenced data forms the basis for asset design, maintenance, and management.
Technologies we use
- Total station and GPS: precision topographic surveys and georeferencing.
- Drone (UAV): rapid aerial acquisition of large, hard-to-access areas.
- LiDAR: High-density laser scanning for detailed point clouds.
- Point cloud and digital twin: 3D models of infrastructure for design and management.
Applications
Our surveys support the design of superstructures and connections, infrastructure condition monitoring, track geometry checks, inventory surveys, and as-built documentation. Point-cloud and digital twin data delivery allows us to work on a faithful digital copy of the asset, reducing on-site inspections and margins of error.
Frequently Asked Questions
What precision do drone and LiDAR surveys guarantee?
The combination of total station, GPS and LiDAR allows for high-precision georeferenced surveys, suitable for railway design.
What do you deliver at the end of the survey?
Planimetric and altimetric analyses, point clouds, and, upon request, a digital twin of the infrastructure that can be used for design and management.
