High-Precision LiDAR Mapping

Q: Why should I choose LiDAR Survey over Photogrammetry for my project?

LiDAR is superior for projects requiring vegetation penetration. While photogrammetry only maps the top surface, LiDAR laser pulses penetrate tree canopies to provide an accurate Digital Terrain Model (DTM) of the ground.

Q: What is the accuracy and point cloud density of Droid Survair’s LiDAR services?

We provide vertical accuracy of 2cm to 5cm with high-density point clouds (100-500+ points/sqm), ensuring high-resolution data for complex engineering and 3D modeling projects.

Q: How does LiDAR technology benefit Powerline and Railway corridor mapping?

LiDAR accurately measures encroachment, wire sag, and track alignment with high precision, making it ideal for safe and efficient corridor inspections.

Q: What are the main deliverables of an Aerial LiDAR Survey?

Deliverables include Classified Point Clouds (.LAS), DTM, DSM, High-Accuracy Contour Maps, and 3D Feature Extraction files.

Q: Can LiDAR be used for Mining and Stockpile Volume Calculation?

Yes, LiDAR provides 99% accurate volume calculations for mining pits and stockpiles, working effectively even in low-light or challenging atmospheric conditions.

LiDAR Survey Services

LiDAR (Light Detection and Ranging) is a modern surveying technology. After Post-processing the data acquired by the LiDAR is used to know the precise elevation and geospatial location of the features captured by it. LiDAR is generally of three types Aerial LiDAR, Terrestrial LiDAR, and Mobile LiDAR. For large-scale mapping and data capturing, we use Aerial LiDAR mounted on a survey-grade drone.

Canopy Penetration

Captures ground data effectively even under dense vegetation, revealing the terrain beneath.

High Accuracy

Delivers millimeter-level precision for creating accurate elevation models and topographical maps.

3D Point Cloud

Generates detailed digital twins of assets, enabling comprehensive 3D visualization and analysis.

Frequently Asked Questions

Why should I choose LiDAR Survey over Photogrammetry for my project?

Unlike Photogrammetry which uses photos to create maps, LiDAR uses laser pulses. The biggest advantage is Vegetation Penetration—LiDAR can see through trees and dense bushes to map the actual ground surface (DTM), whereas Photogrammetry only captures the top of the canopy.

What is the accuracy and point cloud density of Droid Survair’s LiDAR services?

We deliver high-precision results with a vertical accuracy of 2cm to 5cm. Depending on the project requirements, we can capture high-density point clouds ranging from 100 to 500+ points per square meter, ensuring every detail of the terrain is captured for 3D modeling.

How does LiDAR technology benefit Powerline and Railway corridor mapping?

LiDAR is the gold standard for corridor mapping. It accurately measures the distance between power lines and nearby vegetation (Encroachment Analysis), detects wire sag, and maps railway tracks with millimeter precision without any ground-level manual interference.

What are the main deliverables of an Aerial LiDAR Survey?

Our standard deliverables include: Classified Point Clouds (.LAS/.LAZ format), Digital Terrain Models (DTM) & Digital Surface Models (DSM), High-Accuracy Contour Maps, 3D Feature Extraction (Buildings, Trees, Powerlines), and Intensity Maps (reflectivity data).

Can LiDAR be used for Mining and Stockpile Volume Calculation?

Absolutely. LiDAR is incredibly fast and accurate for mining. It can map large pits and complex stockpiles in minutes, providing 99% accurate volume calculations even in low-light conditions where traditional cameras might fail.
