Large-Scale LiDAR Surveys

Efficient Data Capture for Large Properties, Corridors and Regional Projects up to 100+ km²

LiDAR Drone Australia provides high-efficiency aerial LiDAR surveying for large properties, infrastructure corridors and regional-scale projects, with the capability to capture areas extending beyond 100 square kilometres.

​

Large-scale LiDAR projects require careful planning to balance coverage, point density, accuracy, flight efficiency and final deliverables. Our approach is tailored to each project, allowing us to configure the most efficient survey methodology based on the size of the site, terrain, vegetation, required accuracy and intended use of the data.

​

For extremely large projects, we utilise our GS-960 LiDAR sensor, configured for high-altitude, high-efficiency data acquisition. Operating at the maximum allowable height appropriate to the project enables substantially wider coverage per flight, helping reduce the number of flight lines, battery changes and individual missions required across very large survey areas.

​

Large-Area LiDAR Survey Planning

A 5 km² survey and a 100+ km² regional survey require very different operational strategies.

Before commencing a large-scale LiDAR project, we assess the complete project area and develop a flight and data-capture methodology designed around the required deliverables.

​

Considerations include:

• Total project area and boundary configuration

• Terrain and elevation changes

• Vegetation density and canopy

• Required point density

• Horizontal and vertical accuracy requirements

• Flight altitude

• Flight-line spacing and overlap

• Drone endurance and operational efficiency

• Airspace and site restrictions

• Ground Control Point requirements

• Required coordinate system and datum

• Processing and classification requirements

• Final CAD, GIS or survey deliverables

 

This allows the survey to be designed around what the client actually requires, rather than collecting unnecessarily dense data or introducing additional survey control that may not be required for the intended application.

​

GS-960 LiDAR for Extremely Large Projects

For extensive regional projects, long corridors and very large properties, our GS-960 LiDAR system provides an efficient solution for collecting high-density point cloud data over large areas.

​

By operating at an increased flight altitude where operationally permitted, the GS-960 can capture a wider survey swath on each flight line. This can significantly improve productivity when surveying tens or hundreds of square kilometres.

​

The flight plan can be optimised to achieve the required balance between:

• Coverage – maximising the area captured during each mission.

• Point Density – ensuring sufficient LiDAR returns are collected for the intended application.

• Accuracy – configuring the survey methodology to meet the required project tolerances.

• Efficiency – reducing unnecessary flight lines and optimising field time.

• Data Quality – maintaining appropriate overlap and consistency across the complete survey area.

• For extremely large projects, the survey area may also be divided into a series of controlled flight blocks or sectors, allowing data to be progressively captured, processed and quality checked throughout the project.

​

Ground Control — Used Where the Deliverables Require It

Not every LiDAR project requires the same level of ground control.

We determine whether Ground Control Points (GCPs), check points or additional survey control are required based on the accuracy specification and final deliverables.

​

For some large-area applications, the onboard GNSS and inertial navigation solution may provide the level of positioning required without extensive ground control.

​

For projects requiring higher absolute accuracy, engineering integration or survey verification, appropriate ground control and independent check points can be incorporated into the survey methodology.

This allows us to avoid unnecessary field work while still designing the survey to achieve the required outcome.

​

The decision may depend on whether the data is being used for:

• Preliminary engineering and feasibility

• Regional terrain mapping

• Environmental assessment

• Forestry and vegetation analysis

• Flood and catchment modelling

• Detailed engineering design

• Infrastructure planning

• Survey-grade deliverables

• Volumetric analysis

• GIS and asset management

• Digital terrain modelling

​

By designing the control methodology around the required deliverables, we can provide a more efficient and cost-effective solution for large projects.

​

Large Property LiDAR Surveys

Large rural, agricultural, forestry and development properties can be difficult and time-consuming to survey using conventional ground-based techniques alone.

Drone LiDAR allows extensive areas to be captured efficiently while reducing the need for personnel to physically access every section of the property.

​

Typical applications include:

• Large rural properties

• Agricultural land

• Forestry areas

• Development sites

• Mining and quarry areas

• Environmental projects

• Catchments and watersheds

• Flood-prone land

• Bushland and heavily vegetated terrain

• Regional planning projects

​

LiDAR is particularly valuable where the terrain is steep, heavily vegetated, inaccessible or difficult to traverse.

​

Corridor LiDAR Surveys

Large-scale LiDAR is also highly effective for long linear infrastructure projects.

Flight planning can be configured around the corridor alignment, allowing consistent data capture along routes extending for many kilometres.

​

Typical corridor applications include:

• Roads and highways

• Rail corridors

• Transmission lines

• Powerline easements

• Pipelines

• Water infrastructure

• Telecommunications corridors

• Rivers and waterways

• Drainage networks

• Proposed infrastructure alignments

​

The resulting point cloud can provide engineers and consultants with a detailed three-dimensional representation of the terrain, vegetation, structures and existing infrastructure throughout the corridor.

​

Detailed Terrain Information Through Vegetation

One of the key advantages of LiDAR for regional and large-property surveys is its ability to collect multiple returns through vegetation.

​

Where sufficient laser pulses reach the ground, the point cloud can be classified to separate vegetation from ground returns and produce a detailed representation of the underlying terrain.

​

This makes LiDAR particularly valuable for areas containing:

• Trees and forest canopy

• Dense bushland

• Scrub

• Long grass

• Creek lines

• Gullies

• Undulating terrain

• Steep slopes

​

The classified ground data can then be used to generate a Digital Terrain Model, contours, drainage information and other terrain-based deliverables.

​

Large-Scale LiDAR Deliverables

Deliverables can be customised to suit the project and the requirements of your surveyor, engineer, environmental consultant or GIS team.

​

Typical deliverables include:

Classified LiDAR Point Clouds

LAS or LAZ point cloud datasets classified into ground, vegetation and other relevant classes.

​

Digital Terrain Models

Detailed ground-surface models generated from classified LiDAR returns.

​

Digital Surface Models

Surface models incorporating vegetation, structures and other above-ground features.

​

Contours

• Contour datasets generated at project-appropriate intervals.

​

Orthophotography

• High-resolution aerial imagery can be captured in conjunction with the LiDAR survey where required.

​

Cross Sections and Long Sections

• Profiles for roads, rail, pipelines, drainage corridors and other linear infrastructure.​

​

CAD and GIS Data

• Data prepared for integration into common engineering, surveying and GIS workflows.

​

3D Visualisation

• Detailed three-dimensional representations of terrain, vegetation, infrastructure and project areas.​

​

Scalable Surveying from Individual Properties to 100+ km²

Our LiDAR survey methodology is scalable.

A project may involve a single large property, a corridor extending for tens of kilometres, or a regional survey covering 100 square kilometres or more.

​

For each project, we configure the LiDAR system, flight altitude, flight-line spacing, overlap, speed, ground control methodology and processing workflow around the required result.

​

This project-specific approach allows large quantities of high-quality LiDAR data to be captured efficiently without unnecessarily increasing field time, processing requirements or project cost.
