  • Using LiDAR in analyzing the relantionship between vegetation and built space – influences and interdependence. Case Study: Bucharest Municipality

    Author: Sofia Scăunaș, George-Laurențiu Merciu

    Abstract: Under increased urban settlement density, the central areas of cities are usually the main targets of the regeneration process. This action involves modern urban modelling methods to emphasize the buildings structures and vegetation assessment. One of the methods is represented by LiDAR (Light Detection And Ranging) technology. LiDAR offers highresolution imagery for very detailed information on object attributes, such as spectral signature, texture and shape, very accurate position and height information. Recently, remote sensing techniques are being increasingly used for inventory, monitoring and management of vegetation. Precise and up to date spatial information on the current status of green areas is a requirement for the sustainable conservation of urban vegetation. Correct information of urban vegetation is important to preserve the ecological environment within urban spaces. The aim of this study is to expose the utility of the LiDAR technique for assessment of urban vegetation in relation with built-up space in Bucharest Municipality. The results show that spectral details of data reflect the relationships between green areas and their surrounding environment. Urban evolution of Bucharest municipality was very rapid, especially starting with the second half of the 19th century, which led in time to a reduction of the green spaces. Although the capital city has a rich patchwork of green spaces (parks, public gardens, urban lawns, squares) and varied in terms of functionality (for recreation, for decorative purposes, with ecological function), we can observe they are diminishing in the recent years, due to the tendency for expansion of the residential areas.
