W artykule prezentowana jest problematyka przekształceń wielkopłytowych osiedli z drugiej połowy XX wieku, wobec współczesnych potrzeb ich kompleksowej odnowy. Autorzy prezentują na wybranych przykładach, analizę urbanistyczną funkcjonujących kilkadziesiąt lat osiedli. Ulegają one stopniowej degradacji, zużyciu technicznemu, a ich zagospodarowanie przestrzenne odbiega od oczekiwań mieszkańców, zwłaszcza w dobie zmiany modelu społecznego. Analityczne podejście do problemu pozwoli ukazać stan zjawiska oraz predyspozycje, lub ich brak, do przekształceń w ramach działań rewitalizacyjnych.  

Abstract. The paper aims to understand the morphological transformation of the urban network of Wrocław caused by the rapid development and urban growth impacts. In an attempt to investigate the reason for morphological transformation of Wrocław urban network, the study focuses on the analysis of their spatial transformation through the comparative syntactic analysis during the historic process of growth of Wrocław. The spatial analysis based on 'Space Syntax' theories and techniques.

The transformation of the Polish economy in the nineties led to the development of the services sector, often forced by missing alternatives. Along with the development of the capitalist system in Poland the contemporary commercial facilities were appearing. They appeared in the big towns in the early 90s, and in small ones 10 years later. Authors define the place of contemporary commercial buildings 1 in the spatial structure of small towns. Downtown as well as residential and suburban locations are taken into account. The subject to the analysis were 22 towns with population from 4 to 20 thousand inhabitants. Based on statistical data and the different types of locations it proved possible to determine trends that accompanied the development of new forms of trade in small Polish towns over the period of 10 years.

The dynamic development of technology benefits from an access to information about space, and thus this development has a significant impact on the urban form of cities. This applies not only to spatial behaviour of users but also to the principles of spatial policy. The purpose of this study is to systematise knowledge in the field of shaping the development of tall buildings in Poland in the light of available spatial data and their impact on the urban structure of cities. The method of aggregation of spatial data in the form of a point cloud from LiDAR laser scanning was validated; geospatial analysis and map studies in the GIS environment were conducted taking into account trends in building height distribution. The conclusions highlight the primary aim of the latest research methods that can be implemented in the context of urban analysis. The case study of Wrocław shows that the method for the aggregation of spatial data from laser scanning is a universal research tool in the search for trends occurring in the urban form of the city, in particular with relation to building height.
