Essential Guide to Aerial Surveying
Imagine getting a 3D map of your property in a matter of hours, without having to walk every centimeter of the job site. With drone surveying, you can make your surveying projects faster, safer, and more accurate.
Thanks to state-of-the-art LiDAR sensors and photogrammetry, you get georeferenced point clouds, orthomosaics, and digital elevation models that are ready for analysis and design. In this guide, we’ll explore how the technology works, what deliverables you can expect, and why more and more engineers, agronomists, and urban planners are relying on drones for their topographic surveys.
What are drone surveys?
Drone surveys use unmanned aerial vehicles equipped with optical and LiDAR sensors to capture geometric and thermal data from an area. Unlike traditional methods, this technique:
- Reduces field time by up to 5 times
- Penetrates dense vegetation thanks to LiDAR
- Generates GIS- and CAD-ready data

Frequently Asked Questions (FAQ)
Can I get topographic surveys without leaving my office?
Yes. You approve the flight plan and receive the digital deliverables, ready for your review.
Do drones work in forested areas?
LiDAR penetrates dense vegetation and captures only the ground points.
Do I need any special permits?
It depends on local regulations. In general, coordination takes place with the aviation authority, and flight authorizations are processed.
