What is LiDAR Surveying?
LiDAR stands for Light Detection and Ranging. It is a remote sensing technology that emits rapid laser pulses — thousands per second — and measures the time each pulse takes to reflect back from a surface. This data is used to generate highly accurate 3D point clouds representing the exact shape, elevation, and features of any terrain or structure.
Unlike traditional surveying or photogrammetry, LiDAR:
- Penetrates dense vegetation to capture true ground elevation
- Works in low-light and night conditions
- Captures millions of data points per second
- Delivers sub-centimetre accuracy in many applications
- Covers large areas rapidly with drone-based systems
LiDAR has become the standard for large-scale infrastructure projects, corridor surveys, mine volume calculations, and heritage documentation across India.
Types of LiDAR Survey Services We Offer
Our UAV-mounted LiDAR systems cover large areas quickly with exceptional accuracy. Ideal for:
- Highway and railway corridor surveys
- Large agricultural land mapping
- Forest canopy and terrain analysis
- Flood plain and river basin mapping
- Pre-construction topographic surveys
Drone LiDAR is the most efficient method for covering hundreds of hectares in a single mobilisation, reducing survey time by up to 70% compared to traditional methods.
2. Terrestrial LiDAR Scanning (TLS)
Ground-based static LiDAR scanners deliver ultra-high-density point clouds for:
- Building and structure as-built documentation
- Industrial plant and facility mapping
- Heritage and monument documentation
- Bridge and infrastructure inspection
- Underground tunnel and mine scanning
Terrestrial LiDAR captures millions of points from a fixed position, generating millimetre-level detail ideal for engineering and BIM workflows.
3. Handheld & Mobile LiDAR Survey
For areas inaccessible to drones or tripod-mounted scanners, our handheld LiDAR systems provide rapid, accurate capture in:
- Airport terminals and operational infrastructure
- Metro stations and railway platforms
- Indoor environments and confined spaces
- Urban street-level mapping
- Emergency access corridors
Our team successfully completed Handheld LiDAR Survey operations at Delhi International Airport Ltd (GMR Group) — one of India’s most operationally sensitive infrastructure environments — demonstrating our ability to work within strict operational, safety, and security constraints.

DGCA-Certified Drone Pilots
All our UAV operations are conducted by DGCA-certified drone pilots from recognised training schools, ensuring full legal compliance for aerial LiDAR surveys anywhere in India.
Qualified Engineering Team
Our surveyors and geospatial engineers are trained and authorised for all civil and engineering survey work, bringing technical depth to every project deliverable.
LiDAR vs Photogrammetry — Which One Do You Need?
| Parameter | LiDAR | Photogrammetry |
|---|
| Dense Vegetation | Excellent — laser penetrates canopy | Poor — cannot see ground |
| Open Terrain | Very good | Very good |
| Accuracy | Sub-centimetre to 5cm typical | 3–10cm typical |
| Data Volume | Very high point density | Moderate |
| Cost | Higher | Lower |
| Speed | Very fast for large areas | Fast for small areas |
| Night Operations | Yes | No |
| Indoor Use | Handheld LiDAR | Not suitable |
Recommendation: For projects involving vegetation, infrastructure corridors, indoor environments, or night-time operations — LiDAR is the right choice. For open terrain with moderate accuracy requirements and budget constraints, photogrammetry may suffice. Our team will advise the best approach for your specific project.
Our LiDAR Survey Process — Step by Step
Step 1 — Project Brief & Scope Definition We understand your project requirements, area extent, accuracy needs, and deliverable formats before any mobilisation.
Step 2 — Site Reconnaissance & Flight Planning Our team conducts remote site analysis and prepares a detailed survey plan including ground control point (GCP) layout, flight parameters, and safety protocols.
Step 3 — Ground Control Point (GCP) Setup Accurate GCPs are established using DGPS to ensure absolute positional accuracy of all LiDAR data.
Step 4 — LiDAR Data Acquisition Drone, terrestrial, or handheld LiDAR data is captured per the survey plan. Multiple passes ensure complete coverage and redundancy.
Step 5 — Point Cloud Processing Raw LiDAR data is processed using industry-standard software to generate classified point clouds, removing noise and separating ground, vegetation, and structure returns.
Step 6 — Deliverable Generation Final outputs are prepared per your requirements — DEM, DTM, contour maps, 3D models, orthomosaics, BIM-ready point clouds, or GIS layers.
Step 7 — Quality Check & Delivery All data undergoes rigorous QA/QC before delivery. We provide full technical support during client review.

Frequently Asked Questions — LiDAR Survey India
Q1. What is the accuracy of your LiDAR surveys? Our drone LiDAR systems deliver vertical accuracy of ±3–5 cm and horizontal accuracy of ±5–10 cm under standard conditions with properly established GCPs. Terrestrial and handheld systems can achieve millimetre-level accuracy for close-range scanning.
Q2. How large an area can you survey in a day? A drone LiDAR system can typically cover 200–500 hectares per day depending on terrain, flight altitude, and overlap requirements. Terrestrial LiDAR covers smaller areas but with much higher point density.
Q3. Do you need permission to fly drones for LiDAR surveys? Yes. All drone operations in India require prior permissions under DGCA regulations. Our DGCA-certified pilots handle all necessary permissions and comply fully with airspace regulations, including controlled zones near airports and urban areas.
Q4. Can LiDAR survey through tree cover and forests? Yes — this is one of LiDAR’s greatest advantages. Laser pulses penetrate gaps in vegetation to reach the ground, enabling accurate terrain modelling even in dense forest areas where photogrammetry fails.
Q5. What file formats do you deliver LiDAR data in? We deliver in LAS, LAZ, DWG, DXF, SHP, KML, GeoTIFF, and other formats as required by your project or software workflow.
Q6. Can you work at airports and other restricted sites? Yes. Surveying India has experience working at operationally sensitive environments including Delhi International Airport (DIAL). We coordinate all necessary permissions, follow site safety protocols, and work within operational constraints without disrupting ongoing activity.
Q7. How long does a LiDAR survey project take? Typical timelines range from 1–3 days for small sites to 2–4 weeks for large corridor projects. Final deliverables are usually ready within 7–14 days of field completion.
Q8. Do you offer LiDAR survey services across all of India? Yes. We provide LiDAR survey services pan-India including Delhi NCR, Mumbai, Bangalore, Chennai, Hyderabad, Pune, Ahmedabad, Jaipur, Lucknow, Chandigarh, and all tier-2 and tier-3 cities and rural project sites.
Q9. What industries use LiDAR surveys most in India? Infrastructure (highways and railways), mining, aviation, urban planning, agriculture, construction, and forestry are the primary sectors driving LiDAR adoption in India.
Q10. How do I get a quote for a LiDAR survey? Contact us with your project location, area extent (in hectares or km), required accuracy, and deliverable format. We will provide a detailed proposal within 24–48 hours.
