- Urbanization has a far-reaching impact on the environment, economy, politi-cal and social processes. Therefore, understanding the spatial distribution and evolution ofhuman settlements is a key element in planning strategies that ensure the sustainable de-velopment of urban and rural settlements. Accordingly, it is very important to map humansettlements and to monitor the development of cities and villages. Therefore, the problem ofsettlements has found its reflection in the creation of global databases of urban areas. Globalsettlement data have extraordinary value. These data allow us to carry out the quantitativeand qualitative analyses as well as to compare the settlement network at a regional, nationaland global scale. However, the possibility of conducting both spatial and attribute analysesof these data would be even more valuable. The article describes how to prepare raster dataso that they can be implemented into a vector database. It answers the questions whetherit is possible to combine these data with databases available in Poland and what benefits itbrings. It presents the methods of data generalization and the optimization of time and diskspace. As a result of the study, two vector databases with GUF data were developed. Thefirst database resolution is similar to the original (~12 m resolution) database, the seconddatabase contains less detailed (~20 m resolution) data, generalized using mathematicalmorphology. Both databases have been enriched with descriptive data obtained from theNational Geodetic and Cartographic Resource.
