Photogrammetry & specific works

Photogrammetric surveys

Photogrammetry makes it possible to reconstruct an exact 3D copy of land or buildings. Thanks to our expertise in this field, we provide everything from shooting to the completion of the final mapping.


Orthophotographs are aerial or terrestrial images (for facades of buildings or monuments) geometrically rectified and scaled by removing all deformations of parallax and perspective. Our firm has specialized in providing technical imagery specific to the applications of surveyors, architects and archaeologists.

Career surveys

Sewerage surveys
