Available in PDF, EPUB and Kindle. Book excerpt: In order to enable agents to interact with their virtual environment, it is important to provide an explicit representation of the geographic environment in which agents evolve. Such a description should provide agents with quantitative and qualitative information in order to extend their knowledge about their environment and to let them reason about it in order to achieve their goals. This description should include (1) the geometric characteristics; (2) the topological features; and (3) the semantic information which qualifies and characterize the spatial environment. This book presents the state of the art of the generation of explicit representations of geospatial environments. It also outlines the complexity to generate virtual geospatial environments. Finally, it proposes and details a novel approach to automatically generate geometrically-precise and semantically-enriched informed virtual geospatial environments.

This book was released on 2010-10-29 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multi-Agent Geo-Simulation (MAGS) is a modelling paradigm which has attracted a growing interest from researchers and practitioners for the study of various phenomena in a variety of domains such as traffic simulation, urban dynamics, environment monitoring, as well as changes of land use and cover, to name a few. These phenomena usually involve a large number of simulated actors (implemented as software agents) evolving in, and interacting with, an explicit spatial environment representation commonly called Virtual Geographic Environment (VGE). Since a geographic environment may be complex and large-scale, the creation of a VGE is difficult and needs large quantities of geometrical data originating from the environment characteristics (terrain elevation, location of objects and agents, etc.) as well as semantic information that qualifies space (building, road, park, etc.). CurrentMAGS approaches usually consider the environment as a monolithic structure, which considerably reduces the capacity to handle largescale, real world geographic environments as well as agent's spatial reasoning capabilities. Moreover, the problem of path planning in MAGS involving complex and large-scale VGEs has to be solved in real time, often under constraints of limited memory and CPU resources. Available path planners provide agents with obstacle-free paths between two located positions in the VGE, but take into account neither the environment's characteristics (topologic and semantic) nor the agents' types and capabilities. In addition, agents evolving in a VGE lack for mechanisms and tools that allow them to acquire knowledge about their virtual environment in order to make informed decisions. In this thesis, we propose a novel approach to automatically generate a semantically-enriched and geometrically-precise representation of the geographic environment that we call Informed Virtual Geographic Environment (IVGE). Our IVGE model efficiently organizes the geographic features, precisely captures the real world complexity, and reliably represents large-scale geographic environments. We also provide a new hierarchical path planning algorithm which leverages the enriched description of the IVGE in order to support agents' reasoning capabilities while optimising computation costs and taking into account both the virtual environment's characteristics and the agents' types and capabilities. Finally, we propos an environment knowledge management approach to support the agents' spatial decision making process while interacting with the IVGE.
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.

Available in PDF, EPUB and Kindle. Book excerpt: The intersection of two disciplines and technologies which have become mature academic research topics in the 1990s was destined to be a dynamic area for collaboration and publication. However, until now no significant book-length treatment of the meeting of GIS and Virtual Reality has been available. This volume puts that situation to rights by bringing these together to cement some common understanding and principles in a potentially highly promising area for technological collaboration and cross-fertilisation. The result is a volume which ranges in subject matter from studies of a Virtual GIS Room to Spatial Agents, and from an Environmental Multimedia System to Computer-Assisted 3D Geographic Education. All the contributors are well-known international scientists, principally from the computational side of GIS. It will be a valuable resource for any GIS researcher or professional looking to understand the leading edge of this fertile field.
Download or read book GeoSpatial Visual Analytics written by Raffaele de Amicis and published by Springer Science & Business Media. This book was released on 2009-07-11 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: Access, distribution and processing of Geographic Information (GI) are basic preconditions to support strategic environmental decision-making. The heterogeneity of information on the environment today available is driving a wide number of initiatives, on both sides of the Atlantic, all advocating both the strategic role of proper management and processing of environme- related data as well as the importance of harmonized IT infrastructures designed to better monitor and manage the environment. The extremely wide range of often multidimensional environmental information made available at the global scale poses a great challenge to technologists and scientists to find extremely sophisticated yet effective ways to provide access to relevant data patterns within such a vast and highly dynamic information flow. In the past years the domain of 3D scientific visualization has developed several solutions designed for operators requiring to access results of a simulation through the use of 3D visualization that could support the understanding of an evolving phenomenon. However 3D data visualization alone does not provide model and hypothesis-making neither it provide tools to validate results. In order overcome this shortcoming, in recent years scientists have developed a discipline that combines the benefits of data mining and information visualization, which is often referred to as Visual Analytics (VA).

Download or read book IT Roadmap to a Geospatial Future written by National Research Council and published by National Academies Press. This book was released on 2003-05-04 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: A grand challenge for science is to understand the human implications of global environmental change and to help society cope with those changes. Virtually all the scientific questions associated with this challenge depend on geospatial information (geoinformation) and on the ability of scientists, working individually and in groups, to interact with that information in flexible and increasingly complex ways. Another grand challenge is how to respond to calamities-terrorist activities, other human-induced crises, and natural disasters. Much of the information that underpins emergency preparedness, response, recovery, and mitigation is geospatial in nature. In terrorist situations, for example, origins and destinations of phone calls and e-mail messages, travel patterns of individuals, dispersal patterns of airborne chemicals, assessment of places at risk, and the allocation of resources all involve geospatial information. Much of the work addressing environment- and emergency-related concerns will depend on how productively humans are able to integrate, distill, and correlate a wide range of seemingly unrelated information. In addition to critical advances in location-aware computing, databases, and data mining methods, advances in the human-computer interface will couple new computational capabilities with human cognitive capabilities. This report outlines an interdisciplinary research roadmap at the intersection of computer science and geospatial information science. The report was developed by a committee convened by the Computer Science and Telecommunications Board of the National Research Council.

This book was released on 2025-05-09 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Decades of research have shown that disadvantaged communities exist at the intersection of high levels of hazard exposure and poverty. Geospatial environmental justice (EJ) tools, such as the White House Council on Environmental Quality-developed Climate and Economic Justice Screening Tool (CEJST), are designed to integrate different kinds of health, social, environmental, and economic data to identify disadvantaged communities and to aid policy and investment decisions that address the pervasive, persistent, and largely unaddressed problems associated with environmental disparities in the United States. Constructing Valid Geospatial Tools for Environmental Justice evaluates several EJ tools, including CEJST, and provides a conceptual framework and data strategy recommendations for developing the composite indicators that are the heart of geospatial EJ tools. An EJ tool that is transparent, legitimate, and has the trust of its users and the communities it represents is based on a structured iterative process that includes: a clear statement of tool objectives and definitions for the concepts being measured; the selection and integration of data and indicators; and assessment of robustness of the selected data and integration processes. Decisions regarding the tool should be iteratively informed by meaningful community engagement, validation to ensure tool results reflect real-world experiences, and careful and thorough documentation of all decision and data processes.

Download or read book Geospatial Technologies in Environmental Management written by Nancy Hoalst-Pullen and published by Springer. This book was released on 2012-11-06 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geotechnologies and the Environment: Environmental Applications and Mana- ment presents an engaging and diverse array of physically-oriented GIScience applications that have been organized using four broad themes. While the book’s themes are by no means mutually exclusive, Hoalst-Pullen and Patterson provide an elegant overview of the eld that frames the collection’s subsequent thematic str- ture – Wilderness and Wildlife Response; Glaciers; Wetlands and Watersheds; and Human Health and the Environment. Over the course of the volume, the contrib- ing authors move beyond basic (and in some respects clichéd) landscape ecology of land use change to explore human-environment dynamics heretofore not emp- sized in the applied literature. In doing so, the collection presents a compelling case for the importance of developing new physically-oriented GIScience applications that reside at the nexus of social and natural systems with the explicit intent of informing public policy and/or the decision making practices of resource managers. Individually, the chapters themselves are intentionally diverse. The diversity of the approaches, their spatial context, and emphases on management applications demonstrate the many ways in which geotechnologies can be used to address small and big problems in both developed and developing regions. The collection’s int- nal coherence is derived – like the book series – from its explicit appeal to a wide variety of human-environment interactions with potential policy linkages.
