METHOD TO REMOTELY DETECT ASPECT IN REFERENCE POINTS OF AVALANCHE SITE USING LASER RANGE FINDER Russian patent published in 2014 - IPC G01C3/00 

FIELD: measurement equipment.

SUBSTANCE: invention relates to the method for determination of aspect and may be used to determine aspect of an avalanche site. Substance: with the help of a laser range finder placed in a valley, they determine the distance (L₁) to the reference point A at the slope, azimuth and probing angle (β). Then, having displaced a probing beam to a certain distance AB along the horizontal line to the left or right from the reference point A, they determine the distance (L₂) to an arbitrary auxiliary point B on the slope and an azimuth of probing of this point. Then from the projection to the horizontal plane for the values L₁, L₂ and AB, forming a triangle, they determine the azimuth of the horizontal line stretching via the reference A and auxiliary B points on the slope. After that they calculate the aspect.

EFFECT: higher accuracy of remote measurement of aspect in avalanche sites, reduced labour inputs.
