How accurate is drone LiDAR compared to traditional surveying?

Drone LiDAR achieves cm accuracy on hard surfaces when used with RTK positioning and ground control points. For most planning, groundworks and civil engineering applications, the accuracy is indistinguishable from traditional total station surveying - but captured in a fraction of the time.

Can LiDAR penetrate vegetation?

Yes. LiDAR pulses pass through gaps in vegetation canopy, allowing us to capture the ground surface beneath trees and scrub that would be inaccessible or require clearing for traditional survey methods.

What coordinate system do you deliver in?

We deliver in OSGB36 / National Grid by default, tied to Ordnance Survey datum via RTK and ground control points. We can output in other coordinate systems on request.

How large a site can you survey?

Our platform is efficient for sites from 1 hectare up to several hundred hectares. Larger sites are flown over multiple sorties with overlapping flight lines to ensure complete coverage.

What's the turnaround time?

Most projects are delivered within 3-5 working days of capture. Large or complex sites may take longer. Rush turnaround is available on request.

LiDAR Topographic Surveys

Cm-accuracy land and topographic surveys for planning, groundworks and civil engineering.

Overview

What This Service Delivers

We capture dense LiDAR point clouds from the air to produce highly accurate topographic surveys - without the weeks of manual ground work.

Cm accuracy is achievable on hard surfaces, giving you reliable DTM, contour and volume data ready for planning submissions and groundworks design.

Vegetation penetration means we can survey wooded, overgrown or inaccessible terrain that traditional total stations struggle to reach.

Who This Is For

Civil engineers, planning consultants, groundworks contractors, developers and land agents who need accurate topo data for planning, design or volume calculation.

The Process

How We Deliver

From enquiry to delivery, a clear process built around your project needs.

Site Brief & Planning

We review your site boundary, access, required accuracy and deliverables, then plan flight lines and ground control.

Ground Control Points

We establish and survey GCPs across the site to tie the LiDAR data to your required coordinate system and datum.

LiDAR Capture

Our DJI M350 RTK with Rock R3 Pro LiDAR flies pre-planned lines, capturing dense point clouds with RTK positioning.

Data Processing

Point clouds are cleaned, classified and exported as DTM, contours, and your required CAD formats.

Delivery

You receive processed data in your preferred format - DWG, LAS/LAZ, XYZ, or full survey drawings.

Drone vs Traditional

Why Drone Over Traditional Methods

A direct comparison for this service.

Feature	Drone Survey	Traditional Method
Time On Site	Hours to days	Days to weeks
Vegetation Penetration	Yes - ground through canopy	No - requires clearing
Safety Risk	Minimal - no ground access needed	High - surveyors on active sites
Data Density	Hundreds of points per m²	Sparse - spot measurements only
Cost	Lower for sites over 2ha	Higher - more labour hours
Inaccessible Terrain	Easily surveyed	Difficult or impossible
