Next-Generation Aerial Intelligence for Highway Development

Road and expressway construction across India faces tight deadlines, complex terrain, and strict regulatory monitoring. Conventional land survey methods for Detailed Project Reports (DPR) are notoriously time-consuming, prone to traffic risks, and often unable to capture complete terrain variations along winding corridor alignments.

The National Highways Authority of India (NHAI) now mandates monthly drone video recordings and surveys for all national highway projects under execution to ensure transparency, track physical milestones, and verify contractor billing claims.

DronexAviation provides turnkey highway drone solutions. Using long-endurance hybrid VTOL drones equipped with RTK and LiDAR, our survey crews map 30 to 50 linear kilometers of corridor per day without blocking traffic lanes. Deliverables include accurate longitudinal sections (L-sections), cross-sections, cut-and-fill volumetric heat maps, and AI-powered pavement distress classification.

DPR Alignment Topographic Surveys

Map proposed highway corridors with centimetre accuracy. Extract digital elevation models, generate longitudinal profiles and cross-sections at 10m/20m chainage intervals for Civil 3D geometric design.

Cut and fill earthwork calculation for highway
⚒

Cut & Fill Earthwork Reconciliation

Independently calculate excavation cut and embankment fill volumes between project milestones. Compare actual as-built ground levels against design CAD surfaces to prevent contractor over-billing.

NHAI monthly progress video recording
🎬

Mandatory NHAI Monthly Video Audits

Produce standardized 4K geo-referenced video recordings and orthomosaic maps compliant with NHAI Project Monitoring Information System (PMIS) and Data Lake integration.

Pavement distress and crack detection
🔍

Pavement Distress AI Classification

High-resolution nadir imagery processed through machine-learning algorithms automatically detects potholes, longitudinal cracks, alligator cracking, rutting, and ravelling for Pavement Condition Index (PCI) scoring.

Right of way encroachment tracking
🚫

Right-of-Way (RoW) Encroachment Tracking

Document illegal roadside constructions, commercial kiosks, unauthorized median cuts, and boundary wall infringements across the concession zone with indisputable timestamped aerial proof.

Culvert and drainage slope modeling
🌊

Culvert, Bridge & Drainage Modeling

Perform hydrological catchment analysis along highway alignments to size culverts, detect waterlogging vulnerability, and monitor river training works adjacent to major bridge crossings.

Corridor Mapping Execution Framework

Engineered specifically for linear transportation assets spanning tens of kilometers.

01

Chainage & DGPS Control Setup

We establish permanent geodetic benchmark pairs every 3 to 5 km along the highway alignment tied to Survey of India datum using dual-frequency DGPS.

02

Linear Corridor Flight

Long-range VTOL UAVs follow terrain elevation profiles automatically, capturing seamless multi-strip aerial imagery and LiDAR returns along the RoW width (30m to 100m).

03

L-Section & Cross-Section Processing

Point cloud and elevation data is processed into continuous civil models, automatically extracting transverse cross-sections every 10m to 25m chainage.

04

Civil 3D & NHAI Portal Delivery

Data packages are uploaded in Civil 3D formats, interactive cloud viewers, and formatted video archives conforming to NHAI PMIS submission specs.

Frequently Asked Questions

Yes, 100%. NHAI mandates monthly drone video recordings for all National Highway projects. We produce the standardized 4K geo-referenced video logs, True Orthomosaics, and monthly physical progress milestone reports strictly formatted for direct upload into the NHAI Data Lake and PMIS portal.

Physical levelling with auto-levels or total stations only captures points every 10 to 20 meters, missing undulations and irregular stockpiles. Drones capture millions of elevation points per kilometer, creating continuous TIN surfaces that calculate cut/fill volumes with an industry-verified precision within ±1.5% of actual bulk earthwork.

Absolutely. Flying at an altitude of 40 to 60 meters, our ultra-high-resolution cameras capture sub-centimetre pavement imagery while vehicles travel at normal highway speeds below. There is zero need for lane closures, police escorts, or traffic diversions.

We provide LandXML surface models, 3D DWG/DXF drawings, CSV chainage elevation tables, classified LAS point clouds, and high-resolution GeoTIFF orthomosaics that drag-and-drop directly into Autodesk Civil 3D, Bentley OpenRoads, and MX Road.
