Drone Surveying
Lidar and Photogrammetry
What We Offer
Overview
Leveraging cutting-edge drone technology, we offer fast, cost-effective, and highly detailed aerial surveys for a range of industries. Whether it’s land development, construction, mining, or agriculture. Our services provide precise topographic data, 3D maps, and high-resolution imagery that traditional methods can’t match.
Our drone surveying services deliver real-time insights, reduce project timelines, and minimize human error—saving you time and money. Trust us to take your projects to new heights with fast, reliable, and accurate survey solutions.
Why Drone Surveying?
- Fast & Efficient: Collect large amounts of data in a fraction of the time.
- Cost-Effective: Lower operational costs compared to traditional methods.
- Highly Accurate: Achieve pinpoint accuracy for better decision-making.
- Safe & Non-Invasive: Access difficult or hazardous locations with ease.
LiDAR Surveys
Using laser pulses to create a 3D model of earth’s surface, LiDAR technology allows us to map the true ground surface. Unlike photogrammetry, the laser pulses are able to penetrate through dense vegetation, allowing modelling of the ground underneath. This type of survey produces a large point cloud data set which can be further processed and analysed. Below are some examples of what LiDAR data can be used for.
- Digital Elevation Models (DEM)
- Digital Terrane Models (DTM)
- Digital Surface Models (DSM)
- Cross-Sections
- Contours
- Power line corridor mapping
- Volume calculation for earthworks (i.e. cut and fill) or stockpile estimation.
- Forest inventory and management
- Archaeological investigation
Photogrammetry (Arial Photography)
Photogrammetry uses images captured by the drone mounted camera and stitches them together to reconstruct the terrain and what is above it as a photorealistic 3D model or a 2D orthomosaic map. This method is faster than LiDAR but requires sparser vegetation and less complex terrain. Below are some examples of how the data can be utilised.
- Orthomosaic maps
- Creating DEMs (Digital Elevation Models)
- City or Urban mapping
- Construction monitoring
- Geological cliff mapping
Important Details
Below is a table showing the ideal conditions and the specific benefits for each method. Hopefully this will help you decide which survey method suits your project best.
| LiDAR | Photogrammetry |
|---|---|
| Uncleared site with dense vegetation | Cleared site with sparse vegetation |
| Complex terrain | Photorealistic 3D models |
| Accurate ground models | Faster flight times |
| Most weather and lighting conditions | Map larger areas |
If you’re unsure which method would be most suitable, or you are looking for something more specialized, we are happy to discuss the details and see if we can make it work. Please reach out and contact us.
