Motives: Active aging places (AAP) should be identified during the COVID-19 pandemic to ensure the sanitary safety of seniors, prevent older adults from feeling excluded, and eliminate health threats that discourage seniors from being active. Aim: The aim of this study was to apply a new analytical approach with the use of Voronoi diagrams in GIS tools to spatially identify the AAP in the context of apparent social dynamics. Methods: An empirical study was conducted with the use of qualitative (literature review, questionnaire survey, AAP classification, visualization of AAP location with GIS tools) and quantitative methods (AAP ranking based on a statistical analysis of survey responses). Results: Voronoi diagrams were used to determine the accessibility of selected objects in the city of Olsztyn and identify spaces that belong to the social logic of space.
An immanent feature of the housing market is a large spatial dispersion of real estate prices along with their simultaneous high stratification. Application of classic methods of data interpolation results in an excessive simplification of the outcome because of a conversion of the dispersed data sets into areas of spatial continuity by reducing the above-average real estate prices. The main aim of the article was to search for spatial discontinuities of real estate prices’ distribution with 3D modeling using Voronoi diagrams as a method of irregular division of this space. Used methods of geospatial analyses with GIS tools enabled to identify clusters of high housing market activity and to avoid an excessive generalization of data resulting from the reduction of the above-average real estate prices. The research was conducted for over 7000 real estate transactions in years 2010–2017 in Olsztyn, the capital city of Warmia and Mazury in Poland, resulting in a 3D visualization of real estate prices for the chosen market, including the discontinuity in their spatial distribution.
(1) Background: A precise and comprehensive diagnosis of the needs of older adults is the basis for developing concepts of aesthetic functional and spatial arrangements of public open spaces in residential areas that meet their expectations, termed “age-friendly residential areas” (AFRAs). The primary objective of the research was to determine the needs of older people concerning their preferences for the development of AFRAs. (2) Methods: This research was conducted on the basis of a survey conducted from October 2021 to April 2022, involving 1815 older citizens from Poland, Germany, the United Kingdom, the United States, Canada, Croatia, Italy, Lithuania, and Slovakia. The research aimed to determine the needs of older people regarding their preferences for the development of AFRA public open spaces. The developed research approach made it possible to answer the following research questions: (1) What are the needs of different generations of older adults, differentiated by gender and lifestyle, in terms of spatio-functional and landscape aspects with regard to the open spaces of residential estates? (2) Do older citizens from different countries living in various estates (single-family, multi-family) have the same expectations towards AFRAs? (3) Results: The research results showed a high convergence of preferences among older people regardless of gender, age group, or type of residential estate they live in (multi-family/single-family). Slight differences in AFRA preferences were noticed between Polish and non-Polish older adults, most often due to cultural habits. A correlation between the landscape attractiveness and aesthetics of the estate and the comfort of life for the older population, as well as their impact on the final assessment of the estate, was confirmed. As a result of the research, 33 spatio-functional and 16 landscape factors of AFRAs were identified and ranked.
