... hull of the crown as a type of boundary representation. We present an application of this representation for the calculation of geometrical characteristics of common ash ... and tip of each growth unit. A stem analysis gave basal area (at breast height) and bole vol- ume increments for each year. Disks were anal- ysed at 1 year...
