Drone survey is a technique that provides accurate and important details. This is the ideal solution for missions such as facade surveys, industrial survey, interior surveys, volume or cubature calculation, civil engineering surveys, etc.

This technique allows for precision measurements in any terrain. It can be used for 3D modeling of objects, walls, corridors, ceilings, arches, etc. It can also be used to complement a terrestrial or aerial mission.

Our light and easy to use platform for photogrammetric data acquisition allows you to perform exterior and interior terrestrial missions on a variety of sites. With the help of image surveying in the GNSS RTK mode, We are able to perform a wide variety of terrestrial missions with centimeter accuracy.

The processed data offer a comprehensive view of a territory. Drones used by Unitos provide experts in geometrics, topography, architecture and civil engineering with accuracy in terrestrial measurements. With the photogrammetric camera onboard, it is possible to model an area in 3D, enabling the measurement of lengths, areas, volumes, and thus generating an accurate map. the aerial acquired data is geo referenced in real time, allowing a quasi-automatic processing and thus avoiding the need for ground control points. Photogrammetry method uses 3D scenes and measures of spatial positions using a calibrated digital camera with a wide angle lens it is possible to carry out surveys and generate 3D scenes, textured models and orthophotoplans (facades).

Drone surveys involve measuring all elements observable from outside. There is a wide range of survey techniques: terrestrial photogrammetry, aerial photogrammetry, tacheometry, GNSS rover, etc. We use different survey grade drones are used to collect data.
