Full textOver the last thirty years of the twentieth century, irrigation in the French basin of the Rhône river has undergone substantial change. The implementation of a Geographic Information System on the Rhône basin (SIR) demonstrates the existence of four main irrigation systems individualized within several “irrigation regions.” These reveal in turn a series of contrasted dynamics, putting into question the idea that irrigation expansion had been both continuous and homogeneous, even though the total surface area irrigated actually increased. These spatial dynamics can be accounted for by the deep transformations due to a modernised practice that relies on techniques ever more sparing with water. This is in fact the second lesson one can draw from this study : the general increase in irrigated surface areas did not lead to an increase in water demand. On the contrary, water demand has tended to diminish, in the order of 30% over thirty years. Driven by management, the cultivators’ use of water resources is more and more reasoned, so that in the long run irrigation is surely no global threat to environmental balance. The thesis includes a system for managing geographic information as well as an electronic atlas

Full textThis thesis addresses easy and effective development of mapping and transportation applications which especially focuses on the generation of pedestrian networks for applications like navigation, itinerary calculation, accessibility analysis and urban planning. In order to achieve this goal, we proposed a two layered data model which encodes the public space into a hierarchy of semantic geospatial objects. At the lower level, the 2D geometry of the geospatial objects are captured using a planar partition which is represented as a topological 2D arrangement. This representation of a planar partition allows efficient and effective geometry processing and easy maintenance and validation throughout the editions when the geometry or topology of an object is modified. At the upper layer, the semantic and thematic aspects of geospatial objects are modelled and managed. The hierarchy between these objects is maintained using a directed acyclic graph (DAG) in which the leaf nodes correspond to the geometric primitives of the 2D arrangement and the higher level nodes represent the aggregated semantic geospatial objects at different levels. We integrated the proposed data model into our GIS framework called StreetMaker together with a set of generic algorithms and basic GIS capabilities. This framework is then rich enough to generate pedestrian network graphs automatically. In fact, within an accessibility analysis project, the full proposed pipeline was successfully used on two sites to produce pedestrian network graphs from various types of input data: existing GIS vector maps, semi-automatically created vector data and vector objects extracted from Mobile Mapping lidar point clouds.While modelling 2D ground surfaces may be sufficient for 2D GIS applications, 3D GIS applications require 3D models of the environment. 3D modelling is a very broad topic but as a first step to such 3D models, we focused on the semi-automatic modelling of objects which can be modelled or approximated by generalized cylinders (such as poles, lampposts, tree trunks, etc.) from single images. The developed methods and techniques are presented and discussed

Full textIn France, the rapid development of anaerobic digestion (a process used to generate renewable energy by breaking down organic residues) has led to the environmental relevance of this solution being questioned. It is particularly worthwhile evaluating inasmuch as development of the sector forms part of national climate and energy plans. Centralised anaerobic digestion also fits in profitably with various industrial ecology approaches, with the multifunctionality of the process constituting a substantial asset in that it favours circular flows of materials and energy. However, this multifunctionality also represents the main source of the methodological difficulties encountered in the evaluation of the environmental performance of anaerobic digestion systems. Resolving this, i.e. defining the main function of a system, requires the environmental evaluation method to be contextualised. For life cycle assessment (LCA), this contextualisation emerges as being appropriate to the first stage of the methodology. This thesis puts forward a conceptual framework, aimed at defining anaerobic digestion scenarios that are consistent with the particularities of the territory in which they are located. To do this, a territorial systemic approach, involving geographic information systems (GIS) and object-oriented modelling, was developed. The approach has resulted in a spatial model for territorial location of a centralised anaerobic digestion solution, incorporating all its component parts, networks and variables. The systemic approach was followed by a phase of functional and spatial optimisation involving three successive sets of indicators, enabling the following to be defined: (i) the main function to be played by an anaerobic digestion system within the territory studied, (ii) the possible configurations of an anaerobic digestion system capable of fulfilling this main function and (iii) the preferential zones for locating the scenarios envisaged. This methodology, designed to be transposable to any territory within France, forms part of the first two LCA stages, i.e. definition of objectives and life cycle inventory. In order to validate the applicability of the method developed, the territorial systemic approach was applied to two different territories. These case studies highlight the links between specific territorial characteristics and the design of the local solution. The influence of the main function selected for an anaerobic digestion system on the performance and results of the LCA was also studied for one of these territories. The most noteworthy differences relate to substitution, highlighting the importance of developing anaerobic digestion as a priority when the local context makes it possible for the multiple functions of the solution to replace existing sectors with particularly harmful effects on the environment

Full textThis thesis aims at modelling and solving optimization problems related to the management of one-way-electric-car-sharing systems, where users can take a car from a station, use it, and then return it to another station. This generally leads to an imbalanced distribution of cars, with some full stations and other empty ones. A solution to this problem, implemented by car-sharing operators, is to employ staff agents to move cars as needed. However, identifying this need is a non-trivial optimization problem, especially since the system may be more constrained when the vehicles used are electric, which generates battery recharging and autonomy constraints. The global optimization problem addressed is then divided into two sub-problems. The first one is assigning the cars to customers, as well as their routing; it is denoted by ROCSP (Recharging OneWay Car Sharing Problem). The second problem involves agents planning and routing; it is denoted by ESRP (Employee Scheduling Routing Problem). 1. For the ROCSP, we propose two Mixed-integer linear programming (MILP) modelizations of the problem: One based on flows and the other based on paths. This means that the two models include the battery-recharging constraints in two different ways. As the exact resolution through the MILP models is quite expensive in terms of computational time and is not adapted for the resolution of real-size car-sharing instances, we introduce heuristics that enable the optimization of cars-redistribution and service management of the service within a reasonable amount of time. These heuristics allows the calculation of the number of cars and the various redistribution operations to be performed on a given day. 2. For the ESRP, this second problem is also addressed with MILP models for the exact resolution, and some heuristics are suggested for an approximate resolution. This process has reasonable calculation time and aims at finding the minimum number of agents to perform the necessary relocation operations that stem from the first problem, namely, the ROCSP. Once the ROCSP and ESRP solved in their static versions, we then focus on the ROCSP by exploring another variant of the problem : ROCSP with dynamic reservation. We also suggest to explore a new concept : Auto-CoPartage, which is a hybridization of car-sharing and carpooling. The stated algorithms are validated on the Auto Bleue electrical vehicles fleet in the network of the city of Nice, essentially by relying on flow generation models to estimate the demand, but also using other instances that we have generated for other cities. All the data are handled using a Geographical Information System

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 describe a Malaria Early Warning System (MEWS) using various epidemic thresholds and a forecasting component with the support of recent technologies to improve the performance of a sentinel MEWS. Malaria-related data from sentinel sites collected by Short Message Service are automatically stored in a database hosted on a server at Institut Pasteur de Madagascar. Concomitantly our system routinely and automatically acquires site specific satellite weather data related to changes in malaria prevalence such as temperature, rainfall and Normalized Difference Vegetation Index (NDVI). A Malaria Control Intervention data base has also been. This system has already demonstrated its ability to detect a malaria outbreak in southeastern part of Madagascar in 2014. In a second time, we conducted a study to assess the relationship between the effectiveness of mass campaign of long-lasting insecticidal nets (LLIN) over time and malaria outbreaks identified in Madagascar from 2009 to 2015 through the Sentinel surveillance system. This study showed that the difference between efficacy and effectiveness may result in gaps in service coverage during the subsequent years contributing to malaria rebound well before the replacement of the LLINs and highlights the need of continuous distribution mechanism of LLINs.This work aims to maximize the usefulness of a sentinel surveillance system to predict and detect epidemics in limited-resource environments, to guide any changes in the orientation of malaria control programs and to provide practical examples and suggestions for use in other systems or settings

Full textFaced with global phenomena (depletion of fish stocks, environmental degradation, global warming, etc.), which today concern to the global community and more directly the coastal countries, the data series (environmental and biological) should be the more complete and consistent but must be possible to combine simple to answer scientific questions and adapt the action managers.Indeed, the effectiveness of the management of various sources of information is dependent on the integration and interoperability capabilities with partner systems. The data sources are always complementary, because they cover different topics. But, taken in isolation, they often give a fragmented view to answer a scientific question, hence the importance of their integration.Another difficulty lies in the fact that actors who analyze these sources have various views and expertise on the issues raised. Data integration is no longer the only issue, the comments and associated knowledge becomes mandatory and collaborative approaches are an interesting track, if not inevitable with the emergence of socialnetworks and tools that accompany them.This thesis proposes an approach to the implementation of a global information system, a sort of virtual andcollaborative observatory.« Virtual » because it offers a vision via a dashboard of indicators calculated from a warehouse describingdata to be integrated from various information systems heterogeneous and distributed, while respecting the autonomy of the latter. The data warehouse is « virtual », a scheme is designed from a « scientific sheet » model whose schema and content are built « on-the-fly », depending on the user request expressed by SQL queries. The approach thus differs from the standard approach of the conventional warehouses which is based on a predefined schema and a proper integration of the data using materialized views mechanism.« Collaborative » because the approach allows all stakeholders (research, administration, business, etc.),participate in the operation and collective analysis of spatio-temporal data, to produce common knowledge and possibly to provide more substantial underpinning for concerted decisions. The approach relies on advanced collaborative geomatics, innovative method of networking individuals or organizations wishing to collect, process and disseminate information and geographical nature of common interest.The objective is to provide standardized services to enable interoperability and access on data and treatments (metadata, data, access codes) to move towards a transparent and reproducible science (others can appropriate, which is a form of collaboration) but also to call on expertise in the capture of comments made on the scientific sheets (and their components) dashboard that improve the knowledge produced and exchanges between partnersand thus a priori decision making.The chosen solution results in a prototype offering different services to user communities (research, operation and administration of the domain) research services and access to relevant resources (where they are) but also treatment services data (production of indicators, for example) by explaining their reasoning and modeling
