Aerial laser scanning is the fastest, most reliable, and sometimes the only method for collecting data on the real surface, including in hard-to-reach areas and areas covered with forests. Aerial laser scanning provides data on the shape, location and reflectivity of the objects under study.

The result of aerial laser scanning is a 3D array of laser reflection points, classified according to the ground / non-ground basis with a density of up to two hundred points per 1 sq. m and an accuracy of determining their coordinates of 3 — 5 cm in plan and height. The data processing speed is less than 1 hour from the moment of scanning.

The ALS technology is especially effective for work in the development of new fields, engineering and geodetic surveys, creation of a geodetic control basis, inspection of power lines, determination of the relief under dense ground vegetation.
