| summary |
The research analyses the possibility of separating tall greenery as a spatial component of the city in a 3D model based on LiDAR data. This applies in particular to Digital Surface Models (DSMs). The paper presents methods to generate theoretical DSMs of a city without tall greenery and tall greenery only as a component extracted from the 3D model. The first method is based on the use of GIS data, including 2D building outlines. The second method requires additional manual contouring of tall greenery. Both methods have been applied by the author in the planning practice in several cities in Europe. Results of the research are discussed in the article based on the example of Szczecin, Poland. It includes the preparation process, visualisations of theoretical DSM models (buildings without tall greenery and tall greenery only) and their application in urban analyses concerning e.g. protection and development of the cityscape. All simulations have been performed using C++ software developed by the author. |
