Airborne LiDAR + Hydrographic Surveys
We offer Airborne LiDAR, a survey method for everything from wide-area mapping to corridor surveys.
Perfect if you are looking for speed and flexibility across large areas such as cities, forests and farmlands, or long corridors such as power lines, railways, roads and rivers.
Airborne LiDAR (Light Detection and Ranging) technology can offer your business several advantages across a range of industries, from mapping to environmental monitoring.
Benefits of airborne LiDAR solutions are:
1. High Accuracy
Airborne LiDAR captures precise elevation data and surface details, achieving centimetre to sub-metre accuracy.
This makes it ideal for applications like topographic mapping, flood mapping, urban planning, and engineering projects.
2. Fast Data Acquisition
LiDAR systems can rapidly scan large areas, collecting millions of data points in a fraction of the time compared to traditional survey methods. This efficiency is critical for projects with tight deadlines or covering extensive regions.
3. Dense Point Cloud Data
The technology produces high-density point clouds, providing detailed 3D representations of landscapes, buildings, vegetation, and other features. This level of detail supports robust analysis and modelling.
4. Penetration Through Vegetation
LiDAR's ability to penetrate tree canopies using multiple return signals allows accurate mapping of the ground beneath dense vegetation, which is invaluable for forestry management, archaeology, and hydrological studies. The airborne system we use typically out performs UAV systems.
5. Broad Applications
Airborne LiDAR is highly versatile, supporting applications in infrastructure development, flood risk assessment, forestry, agriculture, mining, and coastal erosion monitoring.
6. Digital Elevation and Surface Models (DEM/DSM)
LiDAR data can generate high-quality digital elevation models (DEM) and digital surface models (DSM). These are essential for urban planning, watershed modelling, and infrastructure design.
7. Cost-Effective for Large Areas
For surveying large and remote areas, airborne LiDAR is more cost-effective compared to ground surveys, offering reduced costs and faster completion times.
8. Integration with Other Technologies
LiDAR can seamlessly integrate with traditional survey methods, providing georeferenced 3D data. This integration enhances the accuracy and usability of spatial information.
9. Climate and Environmental Monitoring
LiDAR systems can track environmental changes over time, such as glacier retreat, deforestation, coastal erosion, and urban expansion, supporting climate change studies and sustainable development initiatives.

Airborne LiDAR Capability
Our Airborne laser scanning is a rapid, highly accurate and efficient method of capturing 3D data of large areas, such as agricultural or forestry sites, urban areas, industrial plants, etc.
RIEGL VQ480i scanner to gather high-density point clouds suited for applications in forestry and precision agriculture.
Advanced software allows us to fully interrogate the information included within the scan data.
Multi-target capability enables excellent vegetation penetration and the computing of detailed terrain models.
Point classification is the basis for growth monitoring, height modelling, or the detection of deadfall.
Achieve 15 ~ 30 points per square metre - depending on project requirements
Excellent vegetation penetration rate results in a high number of ground returns that can be used to generate very detailed terrain models.
All points classified as vegetation can be coloured by relative height above ground. This results in a relative estimation model of the trees revealing regions of low and high vegetation stands. Growth rates can be documented by comparison of height models collected over a period of time.
With all vegetation data removed, the remaining points define a very detailed terrain model. This model clearly reveals roads and trenches as well as results of slope instability and erosion.
The aircraft are well suited for this task and are modified solely for aerial surveying. This includes slow flight capabilities and very long endurance flight times, allowing flights which are relatively low and slow and thus capturing great datasets.
Coupled with the LiDAR, we operate 150MP Phase One cameras. These cameras give excellent photo quality and allow photogrammetric orthophotos to be aligned to the LiDAR point cloud. This is very useful for visual reference or other GIS based raster analysis.
Additionally, our team is working to bring Hyperspectral analysis to the Tasmanian market. This technology is in its infancy; however, it will be a game changer for the forestry and agriculture industries.
Vegetation mapping: species classification, forest damages, fire science
Environment: pollution control, enhances the assessment of forest degradation and regeneration, crucial for conservation and climate mitigation strategies.
All our team are all Tasmanian and have capability to work across Tasmania, Vic, NSW and South Australia, other states can be discussed.
