摘要：In this paper, a new approach is presented for the simplification or rather generalisation of building ground plans that are represented as 2D line segments. It is based on half-space modelling and cell decomposition, techniques from the field of computer graphics. As it is important to preserve the overall characteristics of the buildings, the lines are geometrically simplified with regard to geometric relations like orthogonality and parallelism. These characteristics allow for an easy recognition of buildings even on small displays of mobile devices. Such equipment has become a tool for our everyday life in the form of mobile phones, personal digital assistants and GPS assisted navigation systems. Although the computing performance and network bandwidth will increase further, such devices will always be limited by the rather small display area that can be used to communicate the spatial information. This means that an appropriate transformation and visualisation of building data as presented in this paper is essential.
