* This document describes the modeling of 3D objects on the basis of '''existing information'''. In case of lacking information, in particular in case of missing height information, objects must '''explicitly not''' be modeled. For example, if all relevant information on balconies is available, this document provides recommendations for a standardized modeling. Otherwise balconies must not be modeled. | * This document describes the modeling of 3D objects on the basis of '''existing information'''.
