抽象的。本文探讨了激光雷达数据和数字三维城市模型应用的可能性和局限性，以提供高层建筑的专业城市分析。高层建筑的位置和高度是许多城市讨论、冲突和争议的主题。最重要的方面是高层建筑对城市景观、重要地标和其他战略城市景观的视觉影响。这是当今世界城市规划中的一个现实问题。地球上超过50%的高层建筑是在过去15年内建造的。高层建筑可能是一个威胁，特别是对历史发达的城市-典型的欧洲。现代地球观测、越来越多的激光雷达扫描和3D城市模型是更准确地分析高层建筑影响的新工具。本文介绍了适当的模拟技术，几何和计算算法的一般假设-可用的方法和作者开发的个人方法。目标是开发用于GIS表示选定高层建筑对大城市结构视觉影响的几何计算方法。针对这一点，本文介绍了一种视觉影响大小的方法（维斯）.所提出的分析是通过应用机载激光雷达/DSM模型和更多的处理模型（如CityGML），包含几何形状和它的语义。包括模拟进行了一个例子的聚集柏林。
Abstract. The paper examines possibilities and limitations of application of Lidar data and digital 3D-city models to provide specialist urban analyses of tall buildings. The location and height of tall buildings is a subject of discussions, conflicts and controversies in many cities. The most important aspect is the visual influence of tall buildings to the city landscape, significant panoramas and other strategic city views. It is an actual issue in contemporary town planning worldwide. Over 50% of high-rise buildings on Earth were built in last 15 years. Tall buildings may be a threat especially for historically developed cities – typical for Europe. Contemporary Earth observation, more and more available Lidar scanning and 3D city models are a new tool for more accurate urban analysis of the tall buildings impact. The article presents appropriate simulation techniques, general assumption of geometric and computational algorithms – available methodologies and individual methods develop by author. The goal is to develop the geometric computation methods for GIS representation of the visual impact of a selected tall building to the structure of large city. In reference to this, the article introduce a Visual Impact Size method (VIS). Presented analyses were developed by application of airborne Lidar / DSM model and more processed models (like CityGML), containing the geometry and it’s semantics. Included simulations were carried out on an example of the agglomeration of Berlin.
