Drone Surveys & Drone Data Processing
With over 30 years of aerial mapping experience, Landair Surveys brings an accuracy-first approach to every UAV survey. We use both fixed-wing and multi-rotor platforms to capture insightful data across varied and challenging environments.
Every flight is carried out by our CASA-certified, fully insured pilots – with strict safety protocols and quality checks built into every project.
Why choose drone surveying?
Drone surveys deliver high-impact data faster, safer and often at a lower cost than ground-based methods. Choose UAV surveys for:
- Rapid capture over large or hard-to-access sites
- Centimetre-level accuracy with minimal on-ground disruption
- Detailed imagery, surface models and volumetric outputs
- Lower risk – especially for hazardous or sensitive areas
- High-speed data delivery to support tight timeframes
When not to choose drone surveying?
While drone surveys are ideal for localised and high-detail capture, crewed aerial surveying may be a better fit for:
Higher-altitude surveys with wide-angle capture across thousands of sq. km.
Who needs drone surveys?
Drone surveying is a flexible and efficient solution for capturing site-wide data – making it valuable across sectors that demand up-to-date spatial insights.

What do we deliver with drone surveys or data processing?
Whether captured by our pilots or provided by your in-house team, Landair Surveys turns drone imagery into fit-for-purpose outputs. We don’t just supply data. We make sure it’s ready to use!
We regularly work with clients who fly their own drones but require help transforming imagery into usable data.
Orthoimagery
Distortion-free aerial imagery that allows you to directly measure distances and angles – essential for overlaying boundaries, infrastructure or development plans.
Digital Surface Models (DSMs)
Models that show the top of everything – trees, buildings, equipment and vegetation. Useful for visualisation, but not suitable for design or volume calculations.
Digital Terrain Models (DTMs)
Bare-earth models, ideal for engineering design and accurate volume analysis. We also thin these models for more manageable file sizes, without sacrificing accuracy.
2D and 3D feature extraction
Critical topographic detail extracted from the DTM – such as tops and toes of batters, benches, tracks, roads, drainage lines and fences – delivered as strings and lines.
Accurate volume calculations
Cut/fill and stockpile volumes provided with a level of accuracy you can’t get from cloud-only platforms – especially when piles are irregular or partially obscured.
3D models and thermal overlays
Colourised point clouds, textured meshes and thermal heatmaps that enable visualisation, measurement and risk detection.
