Aerial mapping operations
Drone mapping is widely used in construction and land use planning.
Surveyors, design offices, public or private developers and public works companies use it regularly.
Readings are faster than with traditional methods, costs are reduced and risks for personnel are zero. Distance and surface measurements, topographic surveys and cubature calculations are simplified and very precise.
Orthophotography allows to obtain very qualitative aerial views by assembling a very large number of high-definition shots.
These orthoimages are a cheaper alternative to aerial and satellite views. The drone mapping thus produced offers a very high resolution, i.e. an unmatched level of detail.
Orthophotography which is achievable in the visible as well as in the infrared is of interest to many fields: land use planning, works, town planning, environment, agriculture, archaeology, etc.

What is drone mapping used for?
Drone mapping is used to represent an area in plan or elevation, from close-up aerial shots. The drone equipped with a GPS RTK allows to obtain georeferenced maps with great precision.
Aerial mapping allows to carry out a topographic survey, a high-definition plan or even a digital modelling of the terrain in three dimensions.
We can also produce a thermal map showing temperature differences using an onboard infrared camera.
It is then possible to edit the maps in the form of paper plans or to integrate them into a SIG. For greater simplicity and to help you interpret the results, we have developed a dedicated digital tool, available directly via an internet link.

Which applications for orthophotography ?
The realisation of orthophotography by drone in the visible allows to obtain :
- Extensive inspection : allowing you to quickly inspect large areas.
- A precise inspection : access a detailed analysis of your site and defects, up to 1mm/pixel.
- Digital terrain models (DTM) : giving you access to very precise area / distance / angle calculations on your site.
The fields of application of the drone orthophotography are numerous: land use planning, urban planning, environment, agriculture, archaeology, etc.
Inspection by orthophotography, how does it work ?
What is near-infrared orthography ?
Near-infrared drone orthophotography is mainly used in the detection of plant species and the measurement of soil moisture. The possibilities are nevertheless numerous: vitality maps of the plant cover, infestation map, rate of plant cover, disease detection, diagnosis of heterogeneity, etc.
This technology allows to carry out your diagnostic missions quickly, inexpensively and reliably when combined with a drone.
For the realisation of an optimal orthophotography, it is necessary to choose the meteorological conditions with precision (date, time, level / inclination of the sun). At the end of the service, we provide you with a paper or digital report of your analysis area.
What is thermographic drone orthophotography ?
Thermographic drone orthophotography is a fast, affordable solution capable of treating large areas. It is useful in the analysis of heat networks and the thermal coverage of homes.
Infrared orthophotography in the context of heat networks allows the identification of urban heat networks.
This overview remains one of the best methods for inspecting buried networks, because it allows the rapid visualisation of the hot spots of the installation (“hot spots”). The detail of the snapshots greatly facilitates the identification of any anomalies and repair works on the network.
This type of drone orthophotography also allows us to precisely establish the route of the network and to correct the GIS (Geographic Information System) of the operator.
Infrared orthophotography in the building allows the overview of residential areas and the detection of possible heat leaks. It allows a global and quick view of your entire site after assembling the thermographies.
You can then have a reference plane comparison/thermal orthophotography to identify the different areas of thermal weaknesses and the insulation of the structures.
