[Termes IGN] système de gestion de connaissancesRésumé : (auteur) Knowledge Management is a way to answer the problem of capitalizing on the companies’ knowledge. Knowing that hosting sports events (SE) requires organizers to learn from past events to not repeat mistakes, we examine knowledge management in a sport events legacy (SEL). Thus, in this paper, we propose in first, two conceptual models based on UML; one for the SE, another for SEL. Secondly, we propose a system to manage SEL to assist in the process of data acquisition and capitalization on SE knowledge. This system helps to create an open collaborative platform for consultation, visualization of the spinoffs of sport events. It is intended to be used by public policies, territories, journalists, citizens, historians and all others. We propose also to take into account the spatiotemporal aspects of SE.

It increases the artificial lands, which affect the biodiversity, ecosystems, urban climate, and reduces land for agriculture and natural areas. The focus of this thesis is to simulate diverse urbanization scenarios in order to improve public policies decision making. To do this, the SLEUTH model is used in order to investigate the impacts of building types and environmental rules on urban sprawl. In the method used, the SLEUTH model integrates more topographic data, urban tissue and demographic data, including geographical features and the environmental constraints. The main challenge in this research is to propose different urban sprawl scenarios for different kind of environmental rules while taking into account the population demand or at least population growth estimation. The SLEUTH model is one of the well-known cellular automata simulation models, which matches the dynamic simulation of urban expansion and adapts to morphological model of the urban configuration. SLEUTH, like many other urban growth simulation methods, considers only the historical data. Although, the impacts of population growth and urban tissue are implicitly considered during the calibration phase on the historical urban maps, changes in population growth rate or in building types cannot be included in its simulations. Moreover, the SLEUTH results are limited to raster data that are difficult to interpret for decision makers. The results are some pixels on which urbanization is supposed to occur, which do not make much sense from urbanism point of view. Therefore, our research aims to diversify the simulation possibilities integrating explicitly factors of building types according to population growth and providing visual methods to view urban growth scenario results in 2D and even 3D. In order to improve the SLEUTH results, different 2D urban growth simulation scenarios have been defined based on the SLEUTH model by adding buildings type and the estimation of the population growth as urban fabric factors. Each simulation corresponds to policies that are more or less restrictive of spaces considering what these territories can accommodate as a type of building and as a global population. In addition, the simulations can help the user to protect the desired lands such as the environmental spaces from urbanization. These scenarios show the simulation capabilities of the model and make it possible to improve our understanding of an urban sprawl simulation. Three different case studies with various sizes and populations are used including Toulouse metropolitan, Saint Sulpice la Pointe and Rieucros to provide a view of the effectiveness of the proposed method on several scales. The results evaluation indicates that the proposed method makes different simulations that correspond to different land priorities and constraints. It helps to see which land can be protected (where) and how building type can be used to constrain urban sprawl (how much). A 3D representation for each prospective urban growth simulations is provided in order to facilitate the interpretation of the SLEUTH simulation and differentiate the scenarios. The findings allow having different images of the city of tomorrow for applying it to urban policies. Note de contenu : Introduction

[Termes IGN] RomeRésumé : (Auteur) On the Aventine Minor, the oratory of Santa Silvia was home to a community of oriental monks, who, in the first half of the seventeenth century, created a typical Palestinian cemetery with a small monastery that expanded with the growing prestige of the community. The construction of the Basilica of San Saba, above the oratory, was by a group of monks, “the Benedettini di Montecassino,” who lived there in the middle of the tenth century. The substructure was only recovered in the early 1900s. The study of this architectural structure is particularly interesting because there were no complete surveys and the available documentation, as far as we know, was limited to a graphical plan and section. For this reason and due to the archeological significance, it has been selected as a national research project (PRIN 2010–2011). The research has requested detailed documentation through laser scanning and photographic-based documentation. The goal of the present work is to produce a documentation of the oratory from CAD model to the BIM construction.

[Termes IGN] zone saillante 3DRésumé : (auteur) Accurate building rooftop extraction from high-resolution aerial images is of crucial importance in a wide range of applications. Owing to the varying appearance and large-scale range of scene objects, especially for building rooftops in different scales and heights, single-scale or individual prior-based extraction technique is insufficient in pursuing efficient, generic, and accurate extraction results. The trend toward integrating multiscale or several cue techniques appears to be the best way; thus, such integration is the focus of this paper. We first propose a novel salient rooftop detector integrating four correlative RGB-D priors (depth cue, uniqueness prior, shape prior, and transition surface prior) for improved rooftop extraction to address the preceding complex issues mentioned. Then, these correlative cues are computed from image layers created by our multilevel segmentation and further fused into the state-of-the-art high-order conditional random field (CRF) framework to locate the rooftop. Finally, an iterative optimization strategy is applied for high-quality solving, which can robustly handle varying appearance of building rooftops. Performance evaluations in the SZTAKI-INRIA benchmark data sets show that our method outperforms the traditional color-based algorithm and the original high-order CRF algorithm and its variants. The proposed algorithm is also evaluated and found to produce consistently satisfactory results for various large-scale, real-world data sets.

[Termes IGN] semis de pointsRésumé : (Auteur) For years, the Laboratory of Geomatics of the Mediterranean University of Reggio Calabria has undertaken an interdisciplinary project for the recovery and dissemination of information regarding the cultural-artistic and archeological heritage of the metropolitan area. The combined use of geomatics technologies (laser scanners, GPS positioning, digital photogrammetry, remote sensing, GPR) allows on the one hand to investigate objects and artifacts, providing metric, form, and location information; and on the other, to catalog information and make it accessible to the community. Indeed, the digitalization and reconstruction tools of 3D models can be the answer to the limits related to communicability in the archeological sector. Precision, detail, and very accurate photo-realistic reconstructions are particularly useful for virtual and augmented reality applications, integrating them in the devices used on a daily basis. The present note concerns, therefore, the acquisition of information using the point cloud from UAVs and laser scanners, the subsequent 3D modeling, and their representation in an augmented reality (AR) environment using mobile platforms. The application was tested on the church of Sant’Antonio Abate, located in the North of Reggio Calabria, which according to studies is the only evidence of medieval architecture in the territory of Reggio Calabria.
