Full textData warehouse and OLAP systems are decision-making solutions. Integration of spatial data into OLAP systems is an important challenge. Indeed, geographic information is always present implicitly or explicitly into data, but generally it is not well handled into the decisional process. Spatial OLAP (SOLAP) systems, which are the integration of OLAP and Geographic Information Systems (GIS), are a promising way. Most of SOLAP solution reduces geographic information to its spatial component, limiting the analysis capabilities of the spatio-multidimensional paradigm. We propose a formal model (GeoCube) and its associated algebra. GeoCube reformulates main SOLAP concepts in order to introduce semantic and spatial aspects of geographic information into the multidimensional analysis. We model measures and dimension members as geographic and/or complex objects. A measure can belong to one or more hierarchies. We propose an algebra which provides the drill and slice operators, an operator to invert measures and dimension, and two operators to navigate into the hierarchy of the measure. The algebra permits to introduce the spatial analysis methods into multidimensional analysis through some new operators which change dynamically the structure of the hypercube. We have realized a web prototype based on GeoCube. We describe our works using environmental data of Venice lagoon pollution. Finally, we propose a new visualization and interaction paradigm to analyze geographic measures

Full textA huge community of geographical and spatial data users like geologists, militaries, town planners or communication and utilities managers are interested in a Geographical Information System being able to handle the third dimension. Unfortunately, GIS commercial solutions are extremely weak about 3D concern. The purpose of this PhD thesis is to model and implement a 3D GIS prototype, which is able to surpass the simple 3D extrusion of 2D outlines. Our prototype demonstrates that today it is actually possible to deal with true 3D data in a Geographical Information System. The architecture of our prototype is structured on a “Boundary Representation” (B-Rep) geometrical model. This model describes an object as a set of faces, which has the advantage of modeling any kind of forms, even very complex ones. In order to insure a better coherence of data, we have added a “structural” topological layer above the B-Rep geometrical description of the object. A “network” topology is implemented to optimize most of network’s queries inside the application. Finally, the set of geographical data is stored in an extended relational database management system, and a 3D R-Tree spatial index allows a straighter and faster data access. One of the most important contributions of 3D to the geographical information systems lies in the new standing given to visibility computing and to optimal path queries. Our prototype allows to draw visibility maps that take the 3D forms of the terrain and the 3D forms of the geographical objects into account. Those constraints are also considered by our optimal path algorithm, which can be parameterized with visibility maps or with the characteristics of the moving object

Full textThis thesis present a work in computer sciences and software development. This purpose is to try to give an answer to the question : " How to build a full geographic information system following the principles of database management adapting it to geographical data ? ". We try to show with the full example of the Savane system how general theory of geographical data and algorithms in computational geometry may be use to build a GIS software. This work is part of a research program from the IRD (Institut de Recherche pour le Développement). The thesis expose all the architecture, methods and algorithms of the system, trying to explain all the options of the system building, in the different areas : definition and utilization of geographical information ; principles of database management systems and extension to geographical data ; algorithms to use to the implementation of this principles in an information system ; construction of an operational system build from the theoretical principles and functional requirements for the use in projects in geography and research for the development

Full textIn the geographic field as well as other domains such as medicine, documentation or finances, information evolves in time and sometimes in space. It is thus essential to be able to integrate new data coming from multiple and various sources (for example, satellite images or surveyed measures for geographical systems, radiographs or results of analyses for medical information systems, etc. . . ). If this diversity of information is beneficial to ensure the timelessness and richness of the data; it implies problems for acquisition, integration and thus of structuring of multi-source data. We propose a methodology which allows the integration of raster and vector data by the construction of a common structure called "structural map". This structural map is built by successive aggregations based on a Delaunay triangulation. By this way, representation space could be fully described. The structuring of the data is hierarchical. The tree structure allows in particular this propagation of topology and preserves the links with the data sources. The developed methodology was applied to the integration of cadastral data in vector format, and colour aerial photograph in raster format in order to allow their comparison for regular updating

Full textThe identification of coordinate reference systems as well as the knowledge of the transformation algorithms available on the various GIS and Cartography software constitute the necessary condition to localised data handling. However GIS software lacks thoroughness and accuracy in processing reference and coordinates systems. The survey led to the development of an interactive educational tool aimed at non specialist users in the field of geodesy and coordinates. Its function is to process raster and vector data. Its man/machine interface guides users in their choice. An approach to the case of Lebanon is presented to complement this work. It was confronted to the problems of transfer to the new system implemented through the use of a GPS system. Different possibilities of transfer from old to new systems are presented along with the calculated transformation grid

Full textThe amount of data available to geographers has vastly increased leading to the problem of accessing and storing large volume spatial and a spatial data The massive data sets now considered by geographers make it imperative to use efficient methods of storage and access. We propose GEOOQUAD, a prototype GIS designed by solving these problems in the following ways: First, by the application of object-oriented techniques to the abject representation and processing system. The original goal motivating this· prototype GIS was to merge object-oriented language concepts with those of data base systems and produce a programming environment that would be well-suited to the needs of Gis implementers. Second , by the use of more efficient structures for representing spatial data, such as the linear quadtree for regional representation and the B-tree for indexing in the search space

Full textA GIS, in its double role of a ) description and management of geographicla data on a specific space and b) geographicla posotioning of data known as assignees, is a major element of the information system of an organization, and gives way to specific decision making. The present work concerns spatial decision-making, and notably at the strategic level. Spatial dimension adds a complexity to decision-making, and requires a different study and reflection on both the decision situations (i. E. Enterprise management) and the cognitive processes of the decision makers (decision making itself). Our contribution covers methodological and technical solutions to this problem, based on theorical considerations and experimental implementations. These implementations were done within the CERIST (Research Center in Scientific and Technical Information, Algiers), aiming territory development and spatial organisation

Full textBy reviewing fever and hospitalization cases in Libreville, the capital of Gabon, malariacan be pinpointed both in space and time through a notification system which collects and reports data on malaria cases and monitors with a GIS surveillance system. This study concerns children aged 0-14 because of their vulnerability, and focuses on Libreville health centers because they have been using a more complete notification form that includes the patients' geographical origin, since 1999: All clinical data was incomplete containing more informations about the healthcare system functionality and socio-spatial variations of healthcare rather than malaria characteristics in time and space domain. However, statistical analysis of data from the health centers gives better results regarding the determinants to implement in GIS that would facilitate more pragmatic decision-making. Some of these indicators need only to be updated and made suitable for a full-scale study. In order to effectively allocate resources and improved follow-up on malaria cases in children, a thorough understanding of the preconditions are required. A simple 3 year evaluation GIS project is proposed. This methodology may also be used to monitor and manage other vector-borne diseases

Full textIn order to help managers in their choice between environmental planning actions, it would be interesting to build a decision support system against flood phenomena with animated visualisation for results. The flow is modelled by numeric differential equations applied to a digital terrain model which is modelled by a Delaunay triangulation. The followed approach for terrain modelling allows the system to have complete geometric models constructed with a hierarchical structure by existing generated relations between natural phenomena. In addition, a spatial database is built with an object oriented approach. Two kinds of models are used in the system (one for hydrology and the other for hydraulics). In both models, hydrology and hydraulics, there exist some models which are solved by finite differences or by iterative programs of numerical analysis. Hydrologic and hydraulic models need to be applied on geographic objects such as watershed, drainage networks and rivers. Thus, a new method for the extraction of geographic objects from any digital terrain model (DTM) has been implemented. Moreover, these models are applied only under some conditions (morphologic characteristics and soil typologies for example) and they have parameters which evolve from a situation to another. For this reason, we use an inference engine which allows the system to choose an equation with its adequate parameters. The expert system is based on the first order logic with rule production and it is developed with a symbol interpreter named the CIA system. Our system, called SEIGO2, integrates these above mentioned functionalities, and it is implemented on a SUN station. Connecting together GIS (Geographical Information System) functionalities and those of the expert system allows the user to have a set of queries and reasonings on richer data. This system could be used for domains other than water flowing: forest fire diffusion, monitoring ecologic regions, etc

Full textThe anti-vectorial fight is an important constituent for vectorial borne diseases control. The knowledge of the vectors populations as well as their specific composition and spatiotemporal distribution is fundamental for the conception of the strategies of fight against this type of disease.This thesis modeled the spatial distribution of the molecular forms M and S of Anopheles gambiae s.s., major vectors of malaria in Burkina Faso. The modeling was made from the analysis of a series of observations concerning both the vectors and the environment.It proceeds of a combination of concepts and methods of biogeography with techniques and tools of spatial analysis, data analysis and the geographical information systems.We retain of this research work that the abundance of the molecular form S of Anopheles gambiae s.s., decreases as we move from wet regions of the south and the southwest to those the driest of the north and the northeast. The NDVI, the ETP, and the sunshine are the most determining factors of its spatial distribution.In contrast, the abundance of the molecular form M of Anopheles gambiae s.s. increases from the wet regions of the South and the southwest to those drier of the north and the northeast. The temperatures, the pressure, the sunshine and the NDVI are the most determining factors of this spatial distribution.Of these results, were diverted two models which we use to elaborate the Maps of distribution of the molecular forms M and S of Anopheles gambiae s.s.This thesis highlights also the role of the geographical approach in the reflection on health issues and its methodology could be tested on the other sites and for the other vectors of diseases. This methodology could be improved by multi-scale analysis and of temporal variability modeling

Full textGeographic information systems (GIS) are increasingly used for leading historical studies because of their ability to display, store and share geo-historical data. They provide an opportunity for exploring and analyzing spatialized phenomena and the interactions between such phenomena and spatial dynamics. To achieve this goal, GIS have to manage spatio-temporal data describing the transformations of geographical entities. These data are also highly imperfect since knowledge about the past is only available through imprecise or uncertain historical sources such as maps. To date, no GIS is able to integrate, manage and analyze such imperfect data. In this thesis, we focus on the integration of spatio-temporal data about urban space extracted from historical topographic maps on the city of Paris. We propose a process that allows to create spatio-temporal graphs from geohistorical vector data extracted from georeferenced maps of the city. After the analysis of the maps and the measure of their spatial and temporal imperfections, we propose a spatio-temporal model named geohistorical graph and a semi-automatic spatio-temporal data matching process able to build such graphs from vector data extracted from old topographic maps. Our method is tested and validated on the street networks of Paris extracted from maps covering the period from the late XVIIIth century to the late XlXth century

Full textThe general idea of this thesis is to propose a modeling of adaptable information system to any type of cooperation project meeting actors of separate territories, plural cultures and different structural and cyclical contingencies. The decisiveness will be to set up a real “code of communication” around a cooperation project appropriable by all the actors by integrating their specificities and those of their environments. More widely, this thesis is a permanent research framework with capitalization which has to bring to improve “the art of project” notably in terms of information and knowledge flow valuation and that may translate: “think global and act local”. The last two decades were characterized by the emergence of an environment the complexity of which increases in an exponential way in view of the information flow magma to be used. The impact on companies and more generally on organizations fundamentally changed their management and in particular in the “entire process project”. Beyond the concepts of globalization, internationalization, transition, number of organizations is going to try to create some value in the implementation of “cooperation project”. These projects present very particular typologies where the information and knowledge are as well raw materials as finished products in their realization. In this optics, the notion of “the environment project” becomes more and more strong as far as its complexity see increasing by a contingency of factors and actors who do not only arise from “the environment of nearness” of the project but also the “environment of territorial connection” which so redefines the “geospace stakes” of the project. Through this reading of the environment of the project, which codes of communication common we can share to allow of the implementation of “architecture project” in search for efficiency and which has to bring an effect “fast-breeder generator” to the project that is to produce more wealth than consummate resources. To bring an answer to this problem, it is above all to bring to the foreground an abstract model of “informational proactivity management” around the notion of project which can decline in various elements which allow positioning exactly the project in its environment by taking into account "glocality” of its factors and actors. This research is centered on the informative genesis of the constituents of a “proactive management” through returns of experiments and results of construction of an “informative abstract model project” stemming from my research works begun in 1993

Full textOver the years, the usefulness of geospatial data, in any given field, has been well established and countless innovations in the usage of such data have appeared. However, traditional geomatic tools used for the exploitation of data, despite their remarkable technological evolution in recent years, still contain certain limits concerning 3D visualization, interaction and their collaboration capacity that can limit spatial comprehension by a public of non-expert users. To overcome these limits, augmented reality technologies demonstrate interesting possibilities regarding the interaction and visualization of 3D geospatial data. In spite of the recent technological advances, these types of applications remain poorly explored, especially in geospatial contexts. Consequently, the development of geospatial augmented reality systems remains a laborious and experimental process. Considering this, we propose a study to establish the basis for the development of geospatial interactive and collaborative augmented reality systems. We have chosen to inscribe this study in the urban design and planning context, a domain of application for which the interaction and visualization of space plays a central role. The first part of this study presents the results of our literary and conceptual research, undertaken prior to the development of our prototype. The second part presents the prototype developed following the Unified Process methodology for software development as well as the results of the prototype experimentation step conducted afterwards. This research project completed, it appears obvious to us that augmented reality presents an interesting potential to overcome the limits of traditional geomatic tools. However, the realization of a complete solution would require the intervention of a larger pool of resources that are unavailable in the scope of a master’s project.

Full textThe introduction of the data-processing in an organization seems to pose some dilemmas that are due to the encounter of factors of two natures: some classics had to all action of change, the other individuals had to the nature of the abject of the change: the data-processing, first, if for reduce the effect of the change, the best remedy seems the plug in account of the culture of the organization in its largest meaning (know-how, human reports. . . ), how can one lessen nevertheless to imagine the methodical integration of the behavior and the reasoning of the man to the conception of a technical tool ? On the other hand, the reality of ail activity, notably operational as urban management, is characterized naturally by a high detail rate and unforeseen emanating so from men that things, how in this case to establish the relationship between this moving character of reality and the conception of a rational and algorithmic tool? finally, if the concrete conduct of a process of conception, computer applications in our case, cannot happen formalized methods, it remains that the passage of the method to the action in the reality is not always all rest ; there equally the same question : what report would maintain the method with its application ? The thesis plans to approach this problematical through a concrete case, namely the installation of a geographic information system in a given professional world, in the occurrence the direction of the roads of the urban community of Lyon. This enterprise, although amply technical, does not notice solely a technical step. The human aspect translated in the organization and the culture, notably the technical culture, is very important and represents thereby a factor to take into account. The choice of a concrete case is not fortuitous, because it has seemed us difficult to approach a such subject outside of a real context, we have, through our active presence in this context, observed the process of conception of the information system and tried to formalize it

Full textDue to a lot of reasons, i. E. Continuous progress of computer tools in terms of software and hardware, the development of powerful spatial data acquisition tools, the generalization of spatial data and applications for an extended use, etc. A lot of spatial applications, more and more sophisticated, are carried out either as free or commercial tools. The Geographic Information Systems (GIS) are proving to be major consumers of geo-referenced data. They consists in adequate, or even the most appropriate, tools for using such kind of data. Indeed, they offer various features that focus especially on the management, interrogation and representation of spatial data. The real beginning of GIS generalization was in the 1990s. But then, given the limits of computer tools, GIS were mainly interested in 2D spatial data. While at the late 1990s and during the first decade of the 21st century, GIS developers are oriented to the 3rd dimension for spatial data representation. The concept of 3D GIS then became ubiquitous and a widespread research topic around the world. As the progress of GIS is related mainly to advances in computer technology, Internet has become fastly a very promising way for the online dissemination of GIS applications. Thus, the 2D GIS are now multiple over Internet, while 3D GIS are rare. It is in this context that joins our thesis work. Indeed, the main objective is to develop a 3D GIS prototype accessible via Internet. Because GIS are multidisciplinary tools since they rely on very different concepts and technologies (data modeling, databases, development tools, 3D, etc. ), Our thesis work will focus on the basic concepts of 3D GIS, i. E. Three-dimensional spatial data modeling, spatial databases modeling (BDS, spatial data integration in the BDS), carrying out a reflection on the querying functionality of spatial data, a Web application development to access online all services offered by the GIS, etc. As for the technologies to be used for the development of GIS, our choices were oriented mainly to the free tools. The objective is to study the various technologies implemented and their combination for the establishment of a functional 3D GIS accessible over Internet

Full textWe propose a solution for presentation and management of vector multiresolution geodata by taking into account constraints related to mobile context (limitations of storage, displaying capacities and transfer rate). Our solution provides users with the LoD ("Level of Detail") in adequation with scale by respecting the well-known "principle of constant density of data". The amount of data exchanged between client and server is minimized in our system by reusing already locally available data when possible. Increment corresponds to an operation sequence allowing reconstruction of LoD of an object from an available LoD of the same object on the client side. Transferring only increment appears more interesting than downloading an "entire" LoD object. We present models of multi-resolution data and transfer, and principles allowing an incremental management of data in a mobile geodata visualization system. Then we prove interest of our multi-resolution strategy in relation to mono-resolution one
