Services

The Airborne Laser Scanning (ALS) system is an active remote sensor built into the aircraft. The beam emitted by the sensor makes it possible to measure the distance between the system and the surface of objects effectively, obtaining three-dimensional digital data of the surface and terrain with great precision. SAI operates the laser equipment and digital cameras simultaneously, thus obtaining both information in the same flyover. SAI Brasil's aerial surveys can be carried out by helicopter or by plane.
