The tree height, as the vertical distance between the base of the tree and the tip of the highest branch of the tree, represents a key element of forest inventories. In stands where the number of trees is high, the traditional in-situ methods can be time-consuming and can have difficulties in measuring accurately. In this study we present the potential of a low-cost commercial drone-based method of tree height measurement that could be implemented in the sustainable management of forests. Aerial images were acquir...

The forest canopy cover is an important element of forest inventories and it represents the proportion of the ground covered by the vertical projection of the tree crowns. Traditional ground-based methods cannot be efficient in measuring the vertical projection of the tree crowns and in accurately making determinations of forest canopy cover percentage in stands of over a few hectares. The purpose of the current paper is to present the potential of a new approach for forest canopy cover determination that is based...
