3D drone survey

Measure a roof without climbing it.

Fly the drone over the building. A quarter of an hour later you have the three-dimensional model, with the measurements you need to quote the job.

Three steps, and nothing else

You don't need to know how to fly: the drone follows the outline you drew with your finger. And if you already have the photographs, you skip straight to processing.

Draw the area, or upload photos

Open the app in front of the building and tap the roof on the map: route, altitude and number of shots are worked out for you. Already have photographs from another flight? Just upload them.

The drone flies

It takes off, photographs and returns on its own. The photos land on your phone while it is still flying: no memory card to pull out.

Your model arrives

A quarter of an hour after landing the model is ready. Open it, take the measurements, show it to your customer.

We don't hand you a file: we hand you the answer

A 3D model is a file nobody knows what to open with. What you need on site is a number, in the language of your trade.

Measurements are indicative and the level of detail depends on flight altitude: about three centimetres at twenty metres, fourteen at a hundred. Check them before ordering materials. How accuracy works
