We use drones (small unmanned helicopters and planes) for aerial surveys and mapping.

This is achieved by combining low altitude aerial photography with geometrically calibrated cameras and a technique called photogrammetry. With these pictures we create 3D digital elevation and terrain models as well as orthophoto mosaics.

First of all drones are very quick to deploy as they can even be flown with cloud cover.

The results are also better, both in resolution and accuracy, as the pictures are taken much lower than conventional aerial photography.

The individual images can be adjusted for the elevations in the terrain corrected for color differences due to changing weather conditions.

All the pictures can then be joined into a seamless orthophoto mosaic.

As the image is fully to scale it can then be imported directly in a CAD or GIS as a backdrop and used for measuring or mapping.

A picture says a thousand words: with photography we are increasingly reaching limits in terms of perspective. Now the perspective from which the picture is taken is as important as the subject itself.

Unlike planes and helicopters, where the costs quickly mount, micro drones and UAVs allow you to capture breathtaking aerial shots quickly and inexpensively.

Thanks to the GPS-Position-Hold technology, blur-free images can be achieved even in strong winds.

With data transfer to the Ground Station taking place in real time, the camera can be set optimally for the subject, to achieve the best result possible.

To ensure the best possible picture quality, we use only single-lens reflex cameras from established manufacturers.
Our unmanned aircrafts and drones are capable to reach places that are difficult, expensive, dangerous, ‘live’ or even impossible to approach by manned inspection teams.

With different size drones Drones Aviation can inspect indoor, onshore and offshore installations and objects in many different environments. It offers a very cost effective and quick alternative for the traditional manned inspections by scaffolding, crane or rope access which are dangerous, time consuming and costly.

With the unmanned aircraft as platform, a range of remote sensors can be put into position close to the object or installation to be inspected.

Our inspection services are performed as regular, calamity or pre-maintenance inspections in for instance the on- and offshore wind energy and oil & gas industry.

Also in many other industries we inspect installations, buildings, chimneys, telecom- or high voltage pylons.

This way a valuable insight in the asset’s condition is provided enabling our clients to make calculated operational and maintenance decisions without or limiting the turn around or shutdown period. This is all executed in a quick, safe and cost effective manner.
Inspection, Search, Rescue drone services
A search and rescue drone is an unmanned aircraft used by emergency services, such as police officers, fire-fighters or volunteer rescue teams, ideal for searching over vast areas for missing persons and crime victims in need of rescue and in any environment.

Unmanned aerial vehicles (UAVs / drones) can provide real-time visual information and data in the aftermath of an earthquake or hurricane.

These can also become an eye in the sky to locate a lost person (sea, mountains, deserts etc.)

When a disaster or incident threatens lives and livelihoods, emergency responders need information and real-time imagery in order to make better decisions and save time.

Our systems can provide situational awareness over a large area quickly, reducing the time and the number of searchers required to locate and rescue an injured or lost person, greatly reducing the cost and risks of search and rescue missions.

The possibilities for helping ensure public safety are endless.

These UAV/Drones are designed to provide cost effective, real time data and imaging, day or night, in challenging conditions and without risk to personnel.

Aiding in the search for missing persons is the infrared (IR) thermal imaging camera that can detect human body heat.

This capability greatly increases the ability to find people or objects at night that may be hidden, even during daytime operations.

Applications include:

- Search for suspects and missing persons
- Accident or crime scene investigation/documentation
- Search and recovery missions
- Disaster & emergency analysis
Drones in Security & Maritime Security

Drone surveillance enables surreptitiously gathering information about a target as captured from a distance or altitude.

Drones’ flight capabilities, small size and ability to withstand harsh environments mean they can often survey subjects that might not be accessible otherwise and can access a first-person view (FPV) that would normally be impossible for the photographe.


Safely and easily inspect sea and land.
Images are automatically paired with rich metadata and uploaded to the drone cloud for review and sharing.

Field service personnel control the camera and vehicle with familiar tablet gestures, allowing any field service user access to the sky.
