LiDAR (Light Detection and Ranging) sensors acquire details of both the terrain and any above-ground features such as vegetation and infrastructure, with accuracy and resolution unparalleled by other airborne methods. Our fleet of aerial LiDAR sensors can emit up to two million laser pulses per second producing large-scale, high-density, and high-accuracy three-dimensional models of the landscape, whether it be rural, urban, or metropolitan environments.
Aerometrex offers LiDAR surveys and derived outputs tailored to your project requirements. Additionally, we can also supply LiDAR outputs for certain locations off-the-shelf, in areas where we have pre-captured and processed data - allowing for quick turnaround at an efficient cost, helping your business return great value. Aerial imagery is generally acquired alongside our LiDAR surveys providing an additional data set to increase the value of the LiDAR survey.
Our airborne LiDAR sensors can produce multiple elevation measurements resulting in large-scale, high-density, high-accuracy 3D point cloud models of the landscape. These point clouds can be colourised & classified to identify, measure, and visualise a wide range of features.
Large-scale, high-accuracy, classified LiDAR data is the ideal technology for applications within engineering, asset management, construction, environmental consulting, and natural hazard/emergency management. Aerometrex’s fleet of airborne LiDAR sensors can emit up to two million laser pulses per second and the collected data can be processed & classified to one of our three proprietary standards.

LiDAR can penetrate vegetation, deriving highly accurate ground surface models and above-ground features. A wide range of quantitative (DTM, DSM, Contour) & qualitative (Hillshade DTM/DSM) elevation products can be derived from a single survey.
The quantitative datasets have a wide range of uses across the planning of local engineering works, tracking mining operations, city-wide urban planning, landscape-scale groundwater management, and flood mitigation planning. Qualitative datasets are ideal for visualisation purposes and for use as base maps. Elevation measurements derived from airborne LiDAR are highly accurate (up to ±10cm vertical accuracy) and can be defined as either height above sea level or above ground.
Check out this blog post on "LiDAR Derived Elevation Data and Use Cases" which showcases how a wide range of elevation and topography datasets can be derived from a single LiDAR survey.
LiDAR has become an industry standard to accurately map the distribution and 3D structure of vegetation across both urban and rural landscapes.
We provide a wide range of vegetation management datasets including Canopy Height Models (CHM), Foliage Coverage Maps (FCM), Tree Canopy Coverage, and more.
These datasets are ideal for understanding the coverage, density, and three-dimensional structure of vegetation to generate informed management plans and insights relevant to commercial forestry, urban forestry or mine-site rehabilitation, and natural capital monitoring.

Aerometrex LiDAR can help generate quantitative datasets that describe and provide insights for built infrastructure automatically mapped in our surveys, such as buildings.
2D Building Footprints are vector datasets that describe the horizontal extent of structures and can be combined with an nDSM to provide roof height attributes. Another dataset - the Building Height Model is a discontinuous raster that shows the height above ground of buildings above 2m in height that are classified within the LiDAR point cloud. These datasets can help inform urban planning initiatives and prove useful within applications such as flood modelling and bushfire hazard mapping as they are used to understand the hazard/risk relative to built assets.

Aerometrex's LiDAR sensors are dual-mounted with imagery (camera) sensors, enabling us to capture simultaneous aerial imagery during a LiDAR survey. While flight paths are optimised for the LiDAR capture, having this additional dataset offers a valuable visual aid to help interpret features within the 3D LiDAR Point Cloud.
Where possible, and when required, our team can also apply a greater level of post-processing in order to effectively colour balance the imagery and remove distortions and cloud shadows. Having these two complimentary datasets captured simultaneously ensures that you can access the benefits of each and also keep costs under control. With both photogrammetry and LiDAR processing teams in-house at Aerometrex, you can be assured you're receiving the best possible outcomes for your project.
