Aerial orthophotography
Georeferenced orthomosaics at up to 1 cm/pixel, without distortion, using RTK and ground control points. Delivered as GeoTIFF, JPG or PNG, with elevation models and KML/KMZ maps.
Drone orthophotography
Aerial drone orthophotography is an advanced technology in mapping and surface measurement that produces highly accurate georeferenced images. By capturing multiple aerial photographs and then processing them, we generate detailed maps with a spatial resolution of down to a few centimetres per pixel, free of distortion, which ensures a faithful representation of the terrain, infrastructure and vegetation.
It is an indispensable tool for a wide range of applications, from precision agriculture and urban planning to natural resource management and civil engineering.

Technical specifications
- Resolution
Orthomosaics offer exceptional spatial resolution, reaching up to 1 cm/pixel depending on the altitude at which the photographs are taken.
Thanks to the overlap between the photographs, image quality is maintained without introducing distortion, ensuring a faithful representation of the terrain.
- Pixel size
Because drone flights are carried out at a constant altitude, resolution and pixel size remain uniform across the whole surveyed area, guaranteeing consistent, accurate data throughout the digital model.
- Georeferencing
All images are georeferenced, allowing easy integration with geographic information systems (GIS) and other geolocation tools.
- Accuracy
High accuracy is achieved through real-time RTK coordinate correction and by placing ground control points with surveying equipment.
These tools guarantee the reliability and precision of the data, optimising the quality of the models produced.
- Compatibility
Orthomosaics are compatible with a wide range of Geographic Information Systems (GIS), allowing smooth integration into existing workflows. This broadens the possibilities for analysis and visualisation, supporting decisions based on accurate geospatial data.
- Image type
Orthomosaics can be generated from RGB images, giving a faithful representation of the surroundings, or from multispectral images such as RG NIR (Red, Green, Near Infrared and Red Edge), ideal for vegetation studies, precision agriculture and environmental analysis. Orthomosaics can also be generated from IRB FFF thermal images.

Service Applications and Benefits
Aerial drone orthophotography detects structural anomalies and changes in the terrain with high accuracy. It helps identify cracks, subsidence and ground movement in infrastructure and at-risk areas. Integrated with Geographic Information Systems (GIS), it streamlines periodic monitoring and planning in construction and urban development.
Using drones for aerial orthophotography makes inspections fast and safe, shortening lead times and streamlining highly accurate data collection. This method minimises workers' exposure to risk on critical infrastructure and in hard-to-reach areas, and also reduces the cost of data capture.
Models kept up to date with aerial orthophotography support better decisions based on accurate data. With geospatial information constantly updated, changes in the terrain, infrastructure and at-risk areas can be detected in real time. This improves project planning, supervision and control.
Drone orthophotography provides accurate measurements of areas, volumes and distances with high resolution and precise georeferencing. By capturing aerial images and processing them with advanced software, we can carry out topographic surveys and calculate areas and cut and fill volumes, optimising construction, mining and urban development projects

How we work
Step 1: Site information
You tell us the area and the purpose of the job.
Step 2: Flight plan simulation
We estimate how long the survey will take based on the area to be covered and the site conditions.
Step 3: Quote and turnaround
We calculate the processing based on the number of hectares and give you a quote and delivery date.
Step 4: Flight and delivery
We fly, produce the orthomosaic and deliver it georeferenced.

Aerial drone orthophotography is an aerial mapping technique that produces highly accurate georeferenced images. It is used in construction, surveying, agriculture, urban planning and civil engineering to obtain detailed, distortion-free maps of the terrain.
How accurate are drone orthophotos?
Aerial drone orthophotos can achieve a resolution of up to 1 cm/pixel, depending on flight altitude and the type of sensor. Accuracy is ±2 cm, using RTK and ground control points. This allows areas, volumes and distances to be measured precisely.
What measurements can be taken with drone orthophotography?
With aerial orthophotography, areas, distances, cut and fill volumes, slopes and elevations can be calculated with high accuracy. It is a key tool for surveying, mining, construction control and environmental studies. It can also be used to mark out the boundaries of estates and plots.
How long does it take from placing the order to receiving an aerial orthophoto?
The delivery time for aerial drone orthophotography depends on several key factors. Once the client gives us the site information, we run a flight plan simulation to estimate how long the survey will take based on the area to be covered and the site conditions.
Then, depending on the number of hectares to process, we calculate the time needed to process the data and generate the orthomosaic. With these two parameters we prepare a detailed quote and set the best possible delivery date to guarantee highly accurate images and reliable georeferenced data.
What is the difference between an orthophoto and an orthomosaic?
An orthophoto is a single geometrically corrected aerial image, whereas an orthomosaic combines several orthophotos to cover a larger area of land.
