Opis:: Airborne laser scanning (ALS) technology allows accurate information about the forest environment to be obtained. The high precision of ALS allows the detection of individual trees. An individual tree is composed of many elements and requires relatively complex algorithms. Factors that determine and affect the accuracy of calculating the number of trees can be split into the following groups: biological factors, technical factors related to the flight and data acquisition parameters, technical factors related to data processing, problems of results verification. The article synthesizes the main problems arising during the development of methods for detection of individual trees and acquisition of their characteristics in a managed forest in Central Europe.

Opis:: This paper describes a method of determining the stocking density and volume of forest stands based on airborne laser-scanning data. The aim of this study was to determine the relationship between ground-based measurements of standing volume and tree-density, and those acquired based on the Crown Height Model (CHM) interpolated from airborne laser-scanning data. Data were collected from 34 sample plots of two sizes for the CHM analysis: 500 m2 (radius 12.61 m) and 1963.5 m2 (radius of 25.0 m): Trees for sampling were selected using two methods, those whose “centroid” was fully within the sample plot (the tree was considered to be within the sample plot if the centroid of the crown was inside the circle) and those at the “border” (the tree was included in the sample plot if, at least, one part of the contour of the crown was inside the circle). There was a strong relationship (R2 = 0.86) between standing volume measured in sample plots on the ground and the indices produced by the crown elevation model at the locations where the ground-based measurements were performed.

Opis:: precise determination of forest resources is one of the most important tasks in conducting sustainable forest management. Accurate information about the forest’s resources allows for a better planning of current and future management as well as conservation activities. Such precise information is needed by both, individual forest managers and for developing the national forest policy. In recent years, interest in the use of remote sensing in forest inventory has significantly increased. remote sensing allows for non-invasive measurements and the automation of data processing. the most accurate source of remote sensing data at the level of the sample plot is terrestrial laser scanning ( tlS). Its use in forest inventory has been studied for about two decades. this paper aims to introduce studies on state of the art tlS technology as well as provide an overview of research conducted in stands within the temperate climate zone. this article furthermore discusses issues such as tlS data acquisition, data proces- sing and presents results for the estimation of tree biometric features.
