Service Overview

Why Drone Survey for
Highways & Roads?

Traditional highway surveys are slow, expensive, and often dangerous — requiring large teams working on or near live traffic. Our drone-based approach captures the same data in a fraction of the time, with no disruption to traffic and significantly reduced risk.

A corridor survey that traditionally takes 3–4 weeks with a ground team can be completed by our UAV fleet in 2–3 days, delivering higher accuracy data at lower cost.

  • Survey up to 50 km of corridor per day
  • No traffic disruption or lane closures needed
  • Sub-5cm horizontal accuracy with RTK GPS
  • Full 3D terrain model for cut & fill analysis
  • Compatible with AutoCAD, Civil 3D & GIS tools
  • Compliant with NHAI & IRC standards
Applications

Where We Apply This Service

Our highway drone survey service is applicable across multiple project types and phases.

New Highway Construction

Route alignment study, terrain mapping, soil classification corridors, and complete pre-construction survey packages for greenfield highway projects.

Route Alignment Terrain Mapping
Road Widening & Upgradation

Precise cross-section data, existing pavement condition mapping, and volumetric calculations for road widening and upgrading existing corridors.

Cross-Sections Volume Calc
Construction Progress Monitoring

Regular drone flights to track earthwork progress, embankment levels, and compare actual vs planned construction timelines for project managers.

Progress Tracking Earthwork
Bridge & Structure Inspection

Close-range photogrammetric inspection of bridges, culverts, retaining walls, and underpasses for crack detection and structural assessment.

Inspection Structural
Land Acquisition & Utility Mapping

Accurate boundary mapping, structure enumeration, and utility corridor identification for land acquisition and ROW clearance support.

Land Acquisition ROW
As-Built Documentation

Post-construction aerial documentation for as-built record mapping, contractor billing verification, and project handover compliance checks.

How It Works

Our Survey Process

From initial site visit to final data delivery — our structured workflow ensures accuracy, safety, and on-time results every time.
01
Project Briefing & Site Assessment

We review your project scope, corridor length, terrain type, and deliverable requirements. A site recce is conducted for obstacle mapping and airspace clearance planning.

02
Flight Planning & GCP Setup

Automated flight paths are planned for complete corridor coverage. Ground Control Points (GCPs) are placed and surveyed for sub-5cm accuracy georeferencing.

03
UAV Data Capture

Our DGCA-licensed pilots execute flights capturing high-resolution imagery at 70–80% overlap. RTK GPS ensures real-time positioning accuracy during capture.

04
Photogrammetric Processing

Captured images are processed using advanced photogrammetry software to generate orthomosaics, point clouds, DEMs, and 3D terrain models.

05
QA / QC & Accuracy Validation

All outputs undergo rigorous quality checks against GCP accuracy reports. Data is validated to meet project accuracy specifications before delivery.

06
Data Delivery & Support

Final deliverables are packaged in your required formats and shared within 48–72 hours. Full post-delivery support is provided for data integration.

Frequently Asked

Highway Survey FAQs

How accurate is drone survey for highway projects?
With RTK GPS and Ground Control Points, our surveys achieve ±3–5 cm horizontal and ±5–8 cm vertical accuracy — exceeding NHAI specifications for most project stages.
Do you require road closure for the survey?
No. Drone surveys are conducted from the air, requiring no lane closures or traffic disruption. We fly at safe altitudes in compliance with DGCA regulations.
How long does a 10 km corridor survey take?
A 10 km corridor can typically be flown in 1–2 hours. Including GCP setup and data processing, total project delivery is usually 2–3 working days.
What software are your outputs compatible with?
Our deliverables are compatible with AutoCAD, Civil 3D, ArcGIS, QGIS, MicroStation, and most leading engineering and GIS platforms used in highway design.
Can you survey hilly or forested terrain?
Yes. We use terrain-following flight modes for hilly corridors and LiDAR-equipped UAVs for dense vegetation areas where photogrammetry has limitations.
