The aim of this paper is to overview and analyse existing methods for estimation of tree geometric parameters from Airborne Laser Scanning (ALS) data in the context of their possible application for agricultural areas. A detailed description of the estimation methodology proposed by various research groups is presented, including Canopy Height Model creation, tree identification, crown delineation in 2D and 3D, estimation of tree height, crown base height, crown diameters and crown volume. Efficiency and drawbacks of presented methods are identified. It is also analysed, whether the existing methods, originally developed for forestry areas, are suitable for agricultural trees.
