Drone Surveys & Drone Data Processing
With over 30 years of aerial mapping experience, Landair Surveys brings an accuracy-first approach to every drone land surveying project. Using both fixed-wing and multi-rotor RPAs, we capture high-quality data across construction sites, property developments, and remote terrain in Melbourne, Sydney, and regional areas.
Every flight is completed by our CASA-certified, fully insured pilots – with strict safety protocols and quality checks built into every project.
Why drone land surveying?
Drone construction surveys and drone property survey methods deliver high-accuracy data faster, safer and often at a lower cost than traditional land surveying. Choose drone (RPA) surveying for:
- Rapid capture over large areas or hard-to-access sites
- Centimetre-level survey accuracy with minimal on-ground disruption
- High-res imagery, surface models and volumetric outputs
- Lower risk in hazardous or environmentally sensitive areas
- Fast access to real-time insights for project management
When not to choose drone surveying?
While drone surveys excel at detailed, localised mapping, crewed aerial surveys may be more efficient for:
Higher-altitude surveys with wide-angle capture across thousands of sq. km.
Who needs drone surveys?
Drone land surveying is fast, flexible and ideal for capturing topographic data and surface models. We support industries that rely on survey mapping and real-time updates — especially in Melbourne and Sydney.
Architects and heritage specialists
✔ Rooftop and façade mapping
✔ Photogrammetric point clouds for floor plan design
→ Captures architectural detail that's difficult or unsafe to access via ground surveys
Engineers and construction professionals
✔ Pre-, progress and post-build flyovers for drone construction surveys
✔ Earthworks tracking and volumetric surface change detection
✔ Imagery for QA, planning and build verification
→ Monitor change over time and improve survey accuracy
Property consultants and developers
✔ Site-wide, high-resolution imagery from drone property survey
✔ Overlay boundaries, titles and planning data
→ Enable informed due diligence, lease mapping and planning decisions
Mining and quarry operators
✔ Face mapping, pit conditions, and cut/fill calculations
✔ Accurate volumes for stockpile management
✔ Routine scans for progress monitoring
→ Reduce on-site risk and improve resource allocation
Landfill managers and operators
✔ Scheduled thermal flyovers for hotspot detection
✔ Volumetric calculations and surface change tracking
✔ Mapping of utilities and infrastructure
→ Supports environmental compliance and life-of-landfill planning
What do we deliver with drone surveys or data processing?
Whether we capture the data or process your drone footage, we turn raw RPA imagery into accurate, usable survey outputs. Our team supports developers, engineers, and construction firms throughout Melbourne and Sydney.
Our deliverables support drone construction surveys, aerial land survey drone work, and complex survey mapping requirements.
Orthoimagery
Orthorectified aerial imagery suitable for overlays, title plotting, and infrastructure planning. Enables measurement of distances and angles with precision.
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 terrain models ideal for accurate topographic data, engineering design, and drone land surveying outputs. Includes optional thinning for easier integration into design software.
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 captured with sub-decimetre precision – essential for construction site mapping and resource planning.
3D models and thermal overlays
Colourised point clouds, textured meshes and thermal heatmaps that enable visualisation, measurement and risk detection. Ideal for infrastructure, landfill, and high-risk sites.
