  • Method for determination of stand attributes and a computer program for performing the method
    Patent number: 8208689
    Abstract: The method is for forest inventory and for determination of stand attributes. Stand information of trees, sample plots, stands and larger forest areas can be determined by measuring or deriving the most important attributes for individual trees. The method uses a laser scanner and overlapping images. A densification of the laser point clouds is performed and the achieved denser point clouds are used to identify individual trees and groups of trees. A computer program is used for performing the method.
