The drone combined with our high-density and long-range LiDAR enables us to illustrate the morphology of a terrain or infrastructure in a dense, precise, and exhaustive way. Our LiDAR (Light Detection and Ranging) sensors uses three returns, thus allowing us to optimize key ground points even in the presence of vegetation. These are coupled to a GNSS receiver and inertial platform that precisely geolocates each one of the measured points. LiDAR surveys are usually synchronized with aerial photographs that enable the creation of true colored patterns of the LiDAR points and/or orthophotos. Infradrone offers acquisition, processing and analysis services of aerial data that is obtained by LiDAR sensors. The fields of application are multiple and we provide you with the following deliverables from the LIDAR data collected:

​Here are some of the different fields and multiple applications that we can provide you with LiDAR and its data:

-  Topographical plan and contour lines with 3D polyline

-  Cleaned, classified and georeferenced point clouds

-  DTM (digital terrain model) or surface (DSM)

Depending on the type of surface, our approach provides a ground density point varying between (50 to 400 points/m²) and an accuracy in X, Y and Z axes of +/- 5cm. Data can be provided in multiple formats compatible with GIS and CAD software.



Aerial imaging by drone combined with high resolution thermal cameras allows us to precisely georeference images of the thermal inconsistencies. The advantage of thermography is that it allows the detection of anomalies that are not visible to the naked eye. In addition, the integration of a thermographic sensor helps us obtain an accurate overview and covers hard-to-reach areas that are typically not easily accessible with traditional inspection methods.

These analyses are carried out by our certified thermographers at Infradrone. The advantage of our approach is that we can target corrective interventions such as:

​ - Detection of humidity and water infiltration in flat roofs and facades

- Detection of thermal bridging and air infiltration

- Thermal balance of buildings

- Any the other elements where the temperature variations can bring relevant information

The anomalies observed are provided in a summary report with comments, images (videos and photos) and thermal orthophotos. These can be viewed in a GIS or CAD system.  



Drone photogrammetry is a technique that consists of generating a 3D model of reality from a survey of georeferenced stereoscopic images. This technology, compared to traditional survey methods, offers significantly faster results with a higher data density with the possibility of visualizing these results as an up-to-date high-resolution image of a territory.

This technique is very useful in several different fields and makes it possible to precisely measure distances, surfaces and/or volumes. The results are usually presented in the following ways:

​ - Orthophotography (0.5 cm to 5 cm ground resolution)

- Digital terrain and surface model (DTM and DSM)

- 3D point cloud

- Varied analysis


Our approach provides us with a ground image resolution (pixels) of less than 1 cm and an accuracy in X, Y, Z axes of +/- 3 cm.



The use of a drone helps us inspect in full detail any buildings, bridges, communication towers, roads and viaducts or even retaining walls and hydro dams. The visual inspection of a structure is typically done in traditional methods such as elevated platforms or from crane man baskets. Drones and on-board sensors are more efficient. They save time, money and greatly improve the quality of collected data.

Our drone solutions for visual inspections uses high-definition images, coupled with (if necessary): photogrammetric, LiDAR and thermographic surveys, offers many advantages compared to any traditional inspection methods:

- Significantly reduces the occupational safety hazards

- Access to areas that are typically not accessible

- High quality resolution, data, images, videos, models

- Observe any areas in need of maintenance or repairs to help in quick decision making.​

To get a bigger picture and look for any small anomalies such as cracks in the concrete wall, we use different angles and high-quality image resolution that can go up to 1mm per pixel. Furthermore, by using photogrammetry techniques we can carry out any linear measurements and area calculations of the inspected areas. Typically our data comes in picture and video format that is geolocated.
