The French collection of Plan-Reliefs, scale models of fortified towns, constitutes a precious testimony of the history of France. The aim of the URBANIA project is the valorisation and the diffusion of this Heritage through the creation of virtual models. The town scale model of Strasbourg at 1/600 currently exhibited in the Historical Museum of Strasbourg was selected as a case study. In this paper, the photogrammetric recording of this scale model is first presented. The acquisition protocol as well as the data post-processing are detailed. Then, the modelling of the city and more specially building blocks is investigated. Based on point clouds of the scale model, the extraction of roof elements is considered. It deals first with the segmentation of the point cloud into building blocks. Then, for each block, points belonging to roofs are identified and the extraction of chimney point clouds as well as roof ridges and roof planes is performed. Finally, the 3D parametric modelling of the building blocks is studied by considering roof polygons and polylines describing chimneys as input. In a future works section, the semantically enrichment and the potential usage scenarios of the scale model are envisaged.

<p><strong>Abstract.</strong> The object of the study is the survey of minor historic settlements through integrated architectural survey techniques, the BIM modelling for the management of information at multiple levels, and the definition of pattern books to describe the qualities of the place. The research on cultural heritage representation made in Umbria, taking as a case study the historic hamlet of Lizori, a settlement located over the hill between Foligno and Spoleto in the town of Campello sul Clitunno (PG). It was selected as a paradigm of minor village and an experimental model to provide useful reference to reconstruct strategies, which is so important in the area recently affected by seismic events. The purpose of the research is therefore focused on finding a modus operandi in the management of multiple and uneven information. The goal is then to create a digital informative model functional to the conservation and restoration process and a knowledge-based reference for further study.</p>

Abstract. LiDAR technology allows rapid observation of high-resolution and precise 3D point clouds for diverse applications in urban and natural areas. However, uneven density and incomplete point clouds make LiDAR data processing more challenging for the extraction of semantic information on objects and their components. In this paper, we propose a knowledge based semantic reasoning solution for the recognition of building components (e.g. roofs) from segmentation results in the presence of uncertainties in LiDAR point clouds. The proposed solution uses a semantic reasoning approach as well as a similarity evaluation process for object recognition. We apply the proposed method to recognize buildings’ roof styles from a point cloud with uncertainty as a case study.

Subgrid Scale Model

The use of Large Eddy Simulation (LES) is increasingly investigated. However, the LES simulations are computationally demanding, due to the transient nature of the flow computations and the required mesh resolution. Furthermore, the subgrid scale model used for modeling the unresolved flow motions is normally a-priori selected. In an unstructured mesh where the mesh resolution can vary significantly, subgrid scale models should be applied carefully. The present study is aimed to investigate the use of an advanced approach to reduce mesh size by means of a Dynamic Grid Adaptation (DGA) algorithm and to apply a LES subgrid scale model based on local mesh size and flow structure. In this work the DGA algorithm is coupled with the LES turbulence model and made an integral part of the turbulence model. Furthermore, this work has integrated two different LES subgrid scale models which are locally applied to the element in a dynamic manner, dependent on mesh size and flow structure.

This article tackles the relationship between Turkish-Belgian families with the Flemish society, within the specific context of their experiences with early childhood education and care (ECEC) system in Flanders. Our findings are based on a focus group with mothers in the town of Beringen. The intercultural dimension of the relationships between these families and ECEC services is discussed using the Interactive Acculturation Model (IAM). The acculturation patterns are discussed under three main headlines: language acquisition, social interaction and maternal employment. Within the context of IAM, our findings point to some degree of separationism of Turkish-Belgian families, while they perceive the Flemish majority to have an assimilationist attitude. This combination suggests a conflictual type of interaction. However, both parties also display some traits of integrationism, which points to the domain-specificity of interactive acculturation.

Floods are natural risk with a very high frequency, which causes to environmental, social, economic and human losses. The floods in the town happen mainly due to human made activities about the blockage of natural drainage, haphazard construction of roads, building, and high rainfall intensity. Detailed maps showing flood vulnerability areas are helpful in management of flood hazards. Therefore, present research focused on identifying flood vulnerability zones in the Pune City using multi-criteria decision-making approach in Geographical Information System (GIS) and inputs from remotely sensed imageries. Other input data considered for preparing base maps are census details, City maps, and fieldworks. The Pune City classified in to four flood vulnerability classes essential for flood risk management. About 5 per cent area shows high vulnerability for floods in localities namely Wakdewadi, some part of the Shivajinagar, Sangamwadi, Aundh, and Baner with high risk.

Previous planning for rural revival in towns has emphasized construction and government-led policies. However, we argue that the dilemmas of peri-metropolitan rural areas, such as Desakota in China, are far more complex faced with rural super village and hollowed village transformations. Rural revival planning needs to coordinate with the development of urbanized and rural areas towards multifunctional goals and plans as a whole. Therefore, we selected the town master plan of Lijia, a typical peri-metropolitan village in China, as a case study. Through a historical–interpretative approach involving analysis of planning policies, questionnaires, and in-depth interviews with the key stakeholders involved, we structured the process and mechanism of rural revival in Lijia into three phases: resource identification, capitalization, and financialization. In different phases, different stakeholders adopt different roles. The government takes a leading role in resource identification and capitalization, while firms take a leading role in the process of financialization. “Market-dominant and government-guided” planning stimulates villagers to participate in rural revival. We highlight the importance of multifunctional land-use in terms of rural revival in the master planning of peri-metropolitan villages and provide a practical reference for uniting multiple stakeholders, including governments, firms, and villagers.

Abstract The historical autonomy of the religious community of Medina Gounass in Senegal represents an alternative geographic territory to that of colonial and postcolonial states. The borderland location of Medina Gounass allowed the town to detach itself from colonial and independent Senegal, creating parallel governmental structures and imposing a particular interpretation of Islamic law. While in certain facets this autonomy was limited, the community was able to distance itself through immigration, cross-border religious ties, and smuggling. Glovsky’s analysis of the history of Medina Gounass offers a case study for the multiplicity of geographical and territorial entities in colonial and postcolonial Africa.

The paper presents the results of a study on the attractiveness to tourists and natives of the cultural qualities of coastal towns on The Pomeranian Way of St. James that are members of the Cittaslow network. Attention to the quality of urban life is inscribed in the development policies of towns applying to join the Cittaslow movement. In order to join the network (apart from the size criterion), towns need to meet a minimum of 50% plus one of the 72 criteria grouped into seven categories. One of the category is Quality of Urban Life Policy, so the towns applying to join Cittaslow commit themselves to actions aimed at improving the quality of urban life. The study on the attractiveness of cultural qualities of towns to tourists and natives was conducted using the author’s BRB method, whose added value is its universality and the possibility to study small towns regardless of their membership in the Cittaslow network. BRB is an acronym that stands for BUILDINGS, RELATIONSHIPS, BALANCE, and comprises three scopes of activities: BUILDINGS (iconic building and important sites where the inhabitants and the tourists are present); RELATIONSHIPS (the visual effects of the relations between the inhabitants and the town) and BALANCE (solutions that implement modern technologies). This method enables identification of places that are important to the inhabitants, where urban life takes place and which are often created with the involvement of the inhabitants. These are often the same spaces as those that attract tourists and perhaps stimulate them the desire to visit the town again (BRB—be right back). The aim of the BRB method is shown the attractiveness of small towns. The study has shown that the characteristic feature of Polish Cittaslow towns is their diversity: the architectural attractiveness of three towns is high both to tourists and natives. On the other hand, the urban attractiveness of the examined towns is an insufficient.
