Drone surveying
Topographic surveys from the air to capture the real shape of the ground: digital models, contour lines, profiles and volumes, without walking hard-to-reach areas.
What we deliver
- Topographic surveys of sites and plots
- Digital terrain models (DTM) and surface models (DSM)
- Contour lines
- Long profiles and cross-sections
- Volumes of stockpiles, cut and fill
- Georeferenced orthophotos
Delivery formats: DWG · DXF · GeoTIFF · LAS/LAZ · CSV · PDF
Which projects
- Urban development and building projects
- Earthworks and civil engineering
- Quarries, gravel pits and stockpiles
- Estates, farmland and tracks
- Land and landfill restoration
- Feasibility and preliminary studies
Why use a drone
- Large areas in a short time
- No need to walk slopes, stockpiles or unstable ground
- The whole terrain, not just isolated points
- Repeatable flights to compare change over time
How we do it
We agree accuracy, coordinate system and deliverables with you
We plan the flight and the ground control points
We fly and measure the control points
We process the data and deliver it in standard formats
Frequently asked questions
What accuracy can you achieve?
It depends on flight height, equipment and the ground control points measured on site. Before flying we agree the accuracy your project needs and plan the work to achieve it.
Does it work on vegetated land?
Photogrammetry measures the surface visible from the air. Under dense vegetation the ground cannot be seen and another technique, such as LiDAR or supporting conventional survey, may be needed. We assess this case by case.
Which formats do you deliver?
Standard formats for CAD and GIS software: DWG, DXF, GeoTIFF, LAS/LAZ, CSV or PDF, depending on what you need.
What do you need to prepare a quote?
The location, the approximate area, what the survey is for and the accuracy or formats you need. Existing drawings or mapping also help.
