[Termes IGN] villeRésumé : (auteur) Slum detection from satellite imagery is challenging due to the variability in slum types and definitions. This research aimed at developing a method for slum detection based on the morphology of the built environment. The method consists of segmentation followed by hierarchical classification using object-oriented image analysis and integrating expert knowledge in the form of a local slum ontology. Results show that textural feature contrast derived from a grey-level co-occurrence matrix was useful for delineating segments of slum areas or parts thereof. Spatial metrics such as the size of segments and proportions of vegetation and built-up were used for slum detection. The percentage of agreement between the reference layer and slum classification was 60 percent. This is lower than the accuracy achieved for land cover classification (80.8 percent), due to large variations. We conclude that the method produces useful results and has potential for successful application in contexts with similar morphology.

[Termes IGN] villeRésumé : (Auteur) The cartographic identification and characterization of urban settlements is problematic, particularly in varied areas or in large geographical extensions. This is due to the divergence between morphological area structures and data attribution, which is generally available at the level of administrative units. Most existing experiences focus on small regions or use indirect data, from which only indirect information can be derived. This paper proposes an identification of urban settlements in the European Union space, which combines urban population and shape through geographic information system (GIS) techniques. For that purpose, 1 km2 cells with associated population data are used. A procedure is developed establishing three different types of urban settlements, according to population and population density values: high-density urban clusters, small and medium-sized towns, and very small towns. A validation of this procedure is performed using direct survey from local experts in 10 selected study areas. The final results show that 78,307 urban settlements can be identified: 88.17% of them are classified as “very small towns,” 10.75% as “small and medium-sized towns,” and 1.08% as high-density urban clusters. This exercise generates new information for the European Union and surrounding countries, and yields the basis for further research. All GIS operations are performed using vector layers, which is not usual in large-area regional studies.

[Termes IGN] villeRésumé : (Auteur) Urban functions are closely related to people’s spatiotemporal activity patterns, transportation needs, and a city’s business distribution and development trends. Studies investigating urban functions have used different data sources, such as remotely sensed imageries, observation, photography, and cognitive maps. However, these data sources usually suffer from low spatial, temporal, and thematic resolution. This article attempts to investigate human activities to understand urban functions through crowdsourcing social media data. In this study, we mined Twitter and Foursquare data to extract and analyze six types of human activities. The spatiotemporal analysis revealed hotspots for different activity intensities at different temporal resolution. We also applied the classified model in a real-time system to extract information of various urban functions. This study demonstrates the significance and usefulness of social sensing in analyzing urban functions. By combining different platforms of social media data and analyzing people’s geo-tagged city experience, this article contributes to leverage voluntary local knowledge to better depict human dynamics, discover spatiotemporal city characteristics, and convey information about cities.

[Termes IGN] SerbieRésumé : (Auteur) One of the main issues in the current suburban development is mono-functionality. Suburban formats that mainly function as “bedroom communities” are large housing estates, urban sprawl and suburban satellite housing – former villages surrounding large socialist cities. This paper deals with some urban design principles which encourage unsustainable usage of land at the periphery of cities and cause the “bedroom community” phenomenon. A comparative analysis is performed of three suburban areas where the issue of mono-functionality was/ is present, located within the administrative area of the City of Niš, Serbia: large housing estate in Krive Livade neighbourhood, sprawling neighborhoods Podvinik and Vinik, and former rural settlements Donji Komren and Gornji Komren. The quality of urban design is evaluated using four criteria related to the physical and functional component of urban structure: central urban functions, population densities, public spaces adjacent to central urban functions, and neighborhood traffic. The initial hypothesis of this research is that the mono-functionality represents an unsustainable form of development and that the city needs a polycentric spatial structure. The traditional compact neighborhood with a center, which is pedestrian oriented and has a diversity of uses, is instated as a good quality urban area model.
