Why use a drone

Cover an entire site in a single visit

A drone survey captures the whole area in one flight, where ground-based methods proceed point by point. The data is consistent across the site, time-stamped and repeatable: you can revisit a measurement months later without sending a team back into the field.

That consistency matters most for construction monitoring: two surveys taken at different times can be compared directly, making real progress visible, including on areas that are hard to reach or still in operation.

Full traceability of measurements
Direct comparison between two surveys
Access to difficult or operational areas

Our method

How a mission unfolds

Four steps, from the first conversation to the delivery of your data.

01
Scoping
We define together the perimeter, the accuracy required and the format of the deliverables.
02
Flight preparation
Feasibility study, analysis of site constraints and regulatory procedures.
03
On-site acquisition
Our remote pilots operate on site, without interrupting your activity.
04
Processing and delivery
Data processing, quality control and delivery of annotated results.

Nationwide coverage

We operate everywhere in France

Dronexperts operates across the whole of France. Our professional drone pilots travel to wherever your site is, anywhere in the country, and across Europe for the specific missions our industrial clients require.

Our 5 registered training centres — Paris West (Beynes, 78), Strasbourg (Schiltigheim, 67), Toulouse (Labarthe-sur-Lèze, 31), Marseille/Toulon (Le Castellet, 83) and Bordeaux (Mérignac, 33) — act as anchor points so we can reach every region quickly. They are starting bases, not a limit: we operate throughout France, with the same procedures, the same insurance cover and the same standards from one end of the country to the other.

Paris West — Beynes (78)

Our anchor point in Île-de-France: Paris, the inner and outer suburbs and the wider Paris basin.

Strasbourg — Schiltigheim (67)

Our Grand Est base: Strasbourg, Colmar, Mulhouse, Metz, Nancy, Reims and the German and Swiss border areas.

Toulouse — Labarthe-sur-Lèze (31)

Our Occitanie base: Toulouse, Montpellier, Albi, Tarbes, Perpignan and the whole South-West.

Marseille / Toulon — Le Castellet (83)

Our Provence-Alpes-Côte d'Azur base: Marseille, Toulon, Aix-en-Provence, Nice and the Mediterranean coast.

Bordeaux — Mérignac (33)

Head office and historical base of Dronexperts, in Nouvelle-Aquitaine: Bordeaux, La Rochelle, Limoges, Pau, Bayonne.

Is your site far from all five centres? That is not a problem: our bases are starting points, not a service perimeter. We organise travel for the team and the equipment anywhere in France, and across Europe for specific missions, on quotation.
