Article
Housing policies in Tunisia have been marked since the 1970s by both a withdrawal of the State from the production system for the benefit of developers and private developers and by a strong intervention in the rehabilitation of informal settlements. The recourse to an exemption town planning to facilitate the establishment of the specific social h...

Consistent forest loss estimates are important to enforce forest management regulations. In Tunisia, recent evidence has suggested that the deforestation rate is increasing, especially since the 2011’s Revolution. However, no spatially explicit data on the extent of deforestation before and after the Revolution exists. Here, we quantify deforestati...

La question des inégalités socio-spatiales a été au cœur de la mobilisation de 2010-2011 qui a conduit à l’instauration de la deuxième République tunisienne. L’accès aux services et aux équipements, à l’emploi et plus généralement le « droit au développement » ont été parmi les revendications populaires des régions de l’intérieur, au même titre que...

Our study focuses on the task of land use evolution in urban environment which is fundamental in revealing the territorial planning. It refers crucially to the use of spatial data mining tools due to their high potential in handling with spatial data characteristics. The results of our knowledge discovery process are spatial and spatiotemporal asso...

Full-text available
The 2011 Arab uprisings had a strong territorial dimension, highlighting the importance of the territorial aspects of public policies and their failures in terms of equity and development. Thus, decentralization, as a device of institutional re-legitimation, gained a moment of success. In this context, Tunisia and Libya represent two countries that...

Article
Les mutations de l’espace public, dans le double sens de l’espace physique et de l’espace discursif, sont au cœur de la Revolution tunisienne : on les observe dans les nouvelles pratiques spatiales et les nouvelles significations symboliques des lieux. Des mobilisations politiques sont a l’origine des transformations tant des espaces publics urbain...
Article
Full-text available
The study of spatial objects and their evolution is a complex process. Most of the techniques used in this field do not consider the evolution of spatiotemporal relationships. The present paper proposes a new approach for the prediction of the future behaviour of spatiotemporal relationships based on spatiotemporal association rules. Such rules dem...

Cette étude présente les réformes de décentralisation en cours en Tunisie au moment de l'adoption de la Constitution tunisienne. Après un cadrage historique et juridique, elle présente trois secteurs d'action locale en y évaluant le rôle actuel et potentiellement futur des municipalités et des régions: le secteur de l'eau, le secteur de l'énergie e...
Article
A survey of existing literature reveals that all proposed approaches have not considered decision makers' requirements in the design of spatial data warehouses. In the present paper, we propose a model driven architecture-based approach to design spatial data warehouses that integrates spatial and descriptive needs of several decision makers. We st...
Article
La promotion de la gouvernance locale et le renforcement des collectivites territoriales figurent parmi les principales reformes institutionnelles engagees dans la Tunisie « post-revolution ». Cet article propose d’explorer les enjeux et les implications de l’extension du statut communal aux zones rurales. Apres avoir caracterise le systeme de deco...
Article
Since the Tunisian uprising, the territorial issue has been at the forefront of the political and media scene. Parties in the race to the first democratic election of the National Constituent Assembly (NCA) devoted substantial parts of their manifestos to this topic. Through an analysis of the pre-election programmes of the foremost political parti...
Conference Paper
In this paper, we present an approach for the production of origin destination matrices by extracting information from unstructured textual data of websites. This approach, which we called “Origin Destination Matrix Extractor” is based on three main modules of Information Extraction: an extraction of events module with which we tried to extract any...

Association Rule mining is one of the principal research topics in data mining. It is based on finding interesting relationships between item sets and predicts the associative behavior for new data. Nevertheless, these data mining tools cannot effectively handle with dynamic datasets which pose more challenges than mining static data. As it is the...
Conference Paper
Full-text available
Recent modeling approaches were developed to provide a suitable design for Data Warehouses (DW) and Spatial Data Warehouses (SDW) without taking into account spatial decision maker (DM) needs. The generated results are generally not appreciated by DMs. We develop in this paper a spatial DM based approach that integrates automatically DM's standpoin...
Conference Paper
This paper proposes an approach allowing the definition of association rules relative to a future date from sets of rules that are relative to previous dates. The produced rules concern the future land use in urban areas. The suggested approach allows the integration of variable data into existing techniques of spatial data mining. The used process...
Conference Paper
Full-text available
In this paper, we present our approach for mining spatiotemporal knowledge. The proposed method is based on the computation of neighborhood relationships between geographical objects during a time interval. This kind of information is non-explicitly stored in spatio-temporal database and is extracted by the means of special mining queries enriched...

The proposed method is based on the computation of neighborhood relationships between geographic objects during a time interval. This kind of information is extracted from spatiotemporal database by the means of special mining queries enriched by time management parameters...
Article
Future town planners should possess technical knowledge as users of geographical information systems (GIS) as well as certain skills in designing spatial databases and in spatial analysis. They also should understand GIS not only as a tool to be used in their work but also as part of an approach to organize urban planning and management. A Tunisian...
Article
This paper presents an approach to provide urban land use information, from satellite images, that is useful to urban transportation planning. This approach is based on spatial association rules set from general characteristics of urban function distribution. This paper presents also the prototype OSRU which applies this approach and allows to supp...
