Geometric solids for simulation of tree crowns
AbstractGeometric solids are used to simulate tree crowns and their shadows. If real tree crowns cannot be accurately modelled by standard geometric shapes, inaccurate estimates of shadow-pattern location can result. This error may cause substantial inaccuracies in subsequent calculations of tree shade effects on space heating and cooling costs, as well as in estimates of crown volume and leaf surface area. This study found no statistically significant difference between formula- and photoestimated tree crown profile areas when open-grown trees were assigned geometric shapes with a template in the field. Less than 10% mean difference was found between the measures for three crown shapes; parabaloids, vertical ellipsoids and horizontal ellipsoids.
