This book was released on 2002 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce travail de thèse a pour objet le développement d'un modèle numérique de dispersion de particules biotiques, basé sur la résolution des équations de la couche limite atmosphérique. L'accent est porté sur l'élaboration d'un code capable de simuler des écoulements pour des configurations de paysages hétérogènes, car la dispersion des particules est fortement influencée par la structure même du paysage. Le modèle dynamique utilise les équations de Reynolds simplifiées dans le cadre des hypothèses de Boussinesq et la turbulence est traitée par une approche statistique (modèles k-l et k-s). Le système d'équations mis en place permet de modéliser les principaux processus physiques à deux échelles différentes : la modélisation à grande échelle s'appuie sur la théorie de similitude de Monin et Obukhov, qui permet d'élaborer des lois de paroi pour simuler les transferts turbulents entre la surface apparente et la basse atmosphère ; la modélisation à l'échelle du couvert amène à résoudre explicitement l'écoulement dans la sous-couche rugueuse, définie par une canopée végétale, jusqu'à la surface du sol. La dispersion des particules est traitée par une approche eulérienne, qui considère l'ensemble des particules dans l'écoulement comme un champ de concentration continu, dont l'évolution est décrite par une équation de convection-diffusion. Le code de calcul est d'abord validé à partir de données expérimentales acquises dans diverses configurations, en soufflerie comme in situ : transition de rugosité de surface, turbulence en couvert homogène, alternances couvert-clairière-couvert, diffusion de spores en couvert homogène, diffusion de pollen en paysage discontinu. Une série de simulations est ensuite menée pour analyser l'influence de la structure de divers paysages complexes sur la dispersion de particules.
Download or read book Geosimulation written by Itzhak Benenson and published by John Wiley & Sons. This book was released on 2004-08-20 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geosimulation is hailed as ‘the next big thing’ in geographic modelling for urban studies. This book presents readers with an overview of this new and innovative field by introducing the spatial modelling environment and describing the latest research and development using cellular automata and multi-agent systems. Extensive case studies and working code is available from an associated website which demonstrate the technicalities of geosimulation, and provide readers with the tools to carry out their own modelling and testing. The first book to treat urban geosimulation explicitly, integrating socio-economic and environmental modelling approaches Provides the reader with a sound theoretical base in the science of geosimulation as well as applied material on the construction of geosimulation models Cross-references to an author-maintained associated website with downloadable working code for readers to apply the models presented in the book Visit the Author's Website for further information on Geosimulation, Geographic Automata Systems and Geographic Automata Software http://www.geosimulationbook.com
Book Synopsis Virtual Geographic Environments by : Hui Lin
Download or read book Virtual Geographic Environments written by Hui Lin and published by ESRI Press. This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Virtual Geographic Environments, edited by Hui Lin and Michael Batty, collects key papers that define the current momentum in GIS and "virtual geographies." Contributions by leading members of the geospatial community to Virtual Geographic Environments illustrate the cutting edge of GIScience, as well as new applications of GIS with the processing and delivery of geographic information through the Web and handheld devices, forming two major directions to these developments. The four-part organization leads from a primer on VGEs to virtual cities and landscapes, interface design and public participation, and finally mobile and networked VGEs. Current topics, such as crowd sourcing and related services, point to the development of new business models that merge proprietary and nonproprietary systems.
Book Synopsis Urban Remote Sensing by : Xiaojun Yang
Download or read book Urban Remote Sensing written by Xiaojun Yang and published by John Wiley & Sons. This book was released on 2011-04-25 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urban Remote Sensing is designed for upper level undergraduates, graduates, researchers and practitioners, and has a clear focus on the development of remote sensing technology for monitoring, synthesis and modeling in the urban environment. It covers four major areas: the use of high-resolution satellite imagery or alternative sources of image date (such as high-resolution SAR and LIDAR) for urban feature extraction; the development of improved image processing algorithms and techniques for deriving accurate and consistent information on urban attributes from remote sensor data; the development of analytical techniques and methods for deriving indicators of socioeconomic and environmental conditions that prevail within urban landscape; and the development of remote sensing and spatial analytical techniques for urban growth simulation and predictive modeling.

Available in PDF, EPUB and Kindle. Book excerpt: Urban Remote Sensing The second edition of Urban Remote Sensing is a state-of-the-art review of the latest progress in the subject. The text examines how evolving innovations in remote sensing allow to deliver the critical information on cities in a timely and cost-effective way to support various urban management activities and the scientific research on urban morphology, socio-environmental dynamics, and sustainability. Chapters are written by leading scholars from a variety of disciplines including remote sensing, GIS, geography, urban planning, environmental science, and sustainability science, with case studies predominately drawn from North America and Europe. A review of the essential and emerging research areas in urban remote sensing including sensors, techniques, and applications, especially some critical issues that are shifting the directions in urban remote sensing research. Illustrated in full color throughout, including numerous relevant case studies and extensive discussions of important concepts and cutting-edge technologies to enable clearer understanding for non-technical audiences. Urban Remote Sensing, Second Edition will be of particular interest to upper-division undergraduate and graduate students, researchers and professionals working in the fields of remote sensing, geospatial information, and urban & environmental planning.
