Knowledge of forest parameters, such as wood volume, is required for a sustainable forest management. Collecting such information in the field is laborious and even not feasible in inaccessible areas....
A combined analysis of multiple terrestrial laser scanner point clouds recorded from different positions requires a geometric registration of these scans. In most applications of terrestrial laser s...
This study presents a methodology for derivation of fractional canopy cover, detection of main tree species, and extraction of forest stands using logistic regression, airborne remote sensing data and...
Forest management plans are interesting to keep the forest stand natural composite and structure after silvicultural and management treatments. In order to investigate on stand differences made by man...
High densities of palms are common in many tropical forests. In some cases, the dominance of palms has been associated with a depauperate understorey and high rates of native seedling mortality. A va...
A method for extracting forest parameters is described in this paper. The 3D point clouds derived from phase difference laser scanners in forests were processed in a step-wise separation. The first s...
Tree species proportions of forest stands were estimated using data measured by Toposys laser scanner. Employed estimation method was multilayer perceptron neural network with error back-propagation ...
Tree crown size (CS) and stem number per hectare (SN) has become increasingly important for forest management and ecosystem monitoring. Tree crown size is also strongly related to other canopy struc...
The research focused on the mapping, classifying and dealing with forest stands in forest management planning. Stands were analysed in the forest areas of Bohinj (Forest management region Bled) and Po...
Stand structures and spatial patterns were studied in three plots in the beech and silver fir forest on the Karst Plateau in Slovenia. We mapped all stems >10 cm in diameter at breast height (dbh) on ...
The paper describes a computer-supported, impartial method of priority determination for young forest stand tending in homogenous units of forest planning process. The priority of tending activity was...
Stands are the basic unit of forest management and information. The main disadvantage of stands is the labour-intensive updating work needed and the high variance in the quality of the results due t...
