High-precision drone-based surveys for railway line planning, metro corridor mapping, and track infrastructure inspection — delivering centimetre-accurate data safely, quickly, and with zero operational disruption.
Railway corridor surveys have traditionally required large teams working alongside active tracks — a dangerous, slow, and costly approach. Our UAV-based survey method captures the same data from the air, with far greater speed, safety, and accuracy, including areas inaccessible to ground teams.
A 20 km railway corridor survey that takes ground teams 2–3 weeks can be completed by our drone fleet in 3–4 days — including data processing and report delivery, with zero track possession required.
Our railway & metro drone survey is used across planning, construction, and maintenance phases.
Greenfield route surveys for new railway lines — terrain mapping, alignment study, feasibility analysis, and complete pre-engineering survey packages.
Elevated and underground metro route surveys for DMRC, CMRL, and state metro corporations — supporting DPR preparation and detailed design.
Regular aerial inspection of existing track, ballast condition, drainage, slope stability, and embankment erosion — without shutting down operations.
Precise mapping of railway right-of-way (ROW) to detect encroachments, unauthorised structures, and vegetation overgrowth along the corridor.
Close-proximity inspection of railway bridges, viaducts, and tunnels portals for crack detection, spalling, and structural condition assessment.
Detailed aerial survey of station areas, goods sheds, marshalling yards, and maintenance depots for capacity planning and redevelopment projects.
We define the survey corridor extent, chainage limits, accuracy requirements, and deliverable specifications in consultation with your project team.
DGCA airspace permissions, railway department NOC, and safety protocols are secured before any flight operations begin near operational tracks.
Ground Control Points are placed at intervals along the corridor and co-ordinated using DGPS/Total Station for accurate georeferencing of all outputs.
Automated corridor flights capture 70–80% overlap imagery with RTK positioning. Multiple UAVs can be deployed for long corridors to maintain schedule.
Photogrammetric processing generates ortho-images, DEMs, 3D point clouds, and cross-section profiles of the entire railway corridor.
All outputs are packaged in IR/DMRC compatible formats and delivered within 48–72 hours with a complete accuracy and methodology report.
