Book Synopsis GIS and GeoComputation by : Peter Atkinson
Download or read book GIS and GeoComputation written by Peter Atkinson and published by CRC Press. This book was released on 2000-06-21 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geographic Information Systems are computer-based systems for geographic analysis. They have been developed over the past twenty five years and are now widely used. A recent research direction has been the development of geocomputation , representing computer-based geographical analysis beyond the traditional bounds of GIS. In geocomputation, the computer is the research environment itself, not merely a tool. A key to geocomputation it that highly powered computing can be used with sufficient data to avaid traditional parametric approaches altogether. The term geocomputation includes the use of computer-based techniques such as artificial neural networks, genetic programming and fuzzy logic, but in a geographical context. This new book in the prestigious Innovations in GIS series, presents the latest research in geocomputational techniques as presented in the GIS UK Annual Conference.
Book Synopsis GIS And Generalisation by : J-P Lagrange
Download or read book GIS And Generalisation written by J-P Lagrange and published by CRC Press. This book was released on 2020-11-26 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text is the inaugural book in Taylor and Francis's GISDATA series, and is derived from the specialist workshop convened under the auspices of the European Science Foundation's GISDATA Scientific Programme. Generalisation is an integrating tool for the analysis and presentation of spatial data. Effective spatial data analysis requires multiple views of the world at various scales with different thematic layers of representation. Generalisation is a key mechanism in this process, as it filters out information which is required for particular scales or layers; hence it is critical to implement full and comprehensive generalisation capabilities in a GIS, something with which few current GIS are equipped.; This book overviews the core and as-yet unresolved issues surrounding the achievement of this goal, and presents various alternatives - both speculative views and practical examples - in the areas of automated generalisation, vis-a-vis problems such as object simplification and placement. At the same time it distinguishes between modelling with generalisation and graphical representation, and adopts a model-building perspective. It also describes artificial intelligence techniques for implementing automated generalised routines, and addresses issues of data quality and production.; The text is organized into six parts: an introduction; generic issue; object-orientated methods and knowledge-based modelling; knowledge acquisition and representation; data quality; and operation and implementation.
Book Synopsis Generalisation of Geographic Information by : William A. Mackaness
Download or read book Generalisation of Geographic Information written by William A. Mackaness and published by Elsevier. This book was released on 2011-07-28 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: Theoretical and Applied Solutions in Multi Scale Mapping Users have come to expect instant access to up-to-date geographical information, with global coverage--presented at widely varying levels of detail, as digital and paper products; customisable data that can readily combined with other geographic information. These requirements present an immense challenge to those supporting the delivery of such services (National Mapping Agencies (NMA), Government Departments, and private business. Generalisation of Geographic Information: Cartographic Modelling and Applications provides detailed review of state of the art technologies associated with these challenges, including the most recent developments in cartometric analysis techniques able to support high levels of automation among multi scale derivation techniques. The book illustrates the application of these ideas within existing and emerging technologies. In addition to providing a comprehensive theoretical underpinning, the book demonstrates how theoretical developments have translated into commercial systems deployed within NMAs. The book explores relevance of open systems in support of collaborative research and open source web based map services. State of the art review on multi scale representation techniques Detailed consideration of database requirements and object modeling in support of emerging applications (3D, mobile) and innovative delivery (map generalisation services) Illustration through existing map production environment implementations Consolidated bibliography (680 entries), 200 illustrations, author and subject index

Book Synopsis Advances in Spatial Data Handling by : Dianne Richardson
Download or read book Advances in Spatial Data Handling written by Dianne Richardson and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, entitled Advances in Spatial Data Handling, is a compendium of papers resulting from the International Symposium on Spatial Data Handling (SDH), held in Ottawa, Canada, July 9-12, 2002. The SDH conference series has been organised as one of the main activities of the International Geographical Union (IGU) since it was first started in Zurich in 1984. In the late 1990’s the IGU Commission of Geographic Information Systems was discontinued and a study group was formed to succeed it in 1997. Much like the IGU Commission, the objectives of the Study Group are to create a network of people and research centres addressing geographical information science and to facilitate exchange of information. The International Symposium on Spatial Data Handling, which is the most important activity of the IGU Study Group, has, throughout its 18 year history been highly regarded as one of the most important GIS conferences in the world.
Book Synopsis Spatial Information Theory: Foundations of Geographic Information Science by : Daniel R. Montello
Download or read book Spatial Information Theory: Foundations of Geographic Information Science written by Daniel R. Montello and published by Springer. This book was released on 2003-06-30 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 5th International Conference on Spatial Information Theory, COSIT 2001, took place at the Inn at Morro Bay, California, USA, September 19 23, 2001. COSIT grew out of a series of workshops/NATO Advanced Study Institutes/NSF Specialist Meetings during the 1990s concerned with theoretical and applied aspects of representing large scale space, particularly geographic or environmental space (this history is elaborated in the prefaces of previous COSIT proceedings). These are spaces in which (and on which) human action takes place, and which are represented and processed in digital geographic information systems. In these early meetings, the need for well founded theories of spatial information representation and processing was identified, particularly theories based on cognition and on computation. This concern for theory provided an early foundation for the newly emerging field of geographic information science. COSIT is not backed by any particular scientific society but is organized as an independent enterprise. The conference series was established in 1993 as an interdisciplinary biennial European conference on the representation and processing of large scale spatial information after a successful international conference on the topic had been organized by Andrew Frank et al. in Pisa in 1992 (frequently referred to as "COSIT 0"). After two successful European COSIT conferences with strong North American participation (COSIT ’93: Island of Elba, Italy; COSIT ’95: Semmering, Austria), COSIT ’97 moved across the pond to the United States, and was held in the Laurel Highlands, Pennsylvania.

Book Synopsis Spatial Information Theory by : Andrew U. Frank
Download or read book Spatial Information Theory written by Andrew U. Frank and published by Springer Science & Business Media. This book was released on 1993-09-02 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume collects the papers presented at the European Conference on Spatial Information Theory (COSIT '93) held on the island of Elba, Italy, inSeptember 1993. Spatial information theory includes disciplinary topics and interdisciplinary issues dealing with the conceptualization and formalization of large-scale (geographic) space. It contributes towards a consistent theoretical basis for Geographic Information Systems (GIS). Geographic information systems are widely used in administration,planning, and science in many different countries, and for a wide variety ofapplications. Research results which relevant for GIS are distributed between many disciplines and contacts between researchers have been limited. At the same time, the development of GIS has been hinderedby the lack of a sound theoretical base. This conference was intended to help remedies these problems.

Book Synopsis Abstracting Geographic Information in a Data Rich World by : Dirk Burghardt
Download or read book Abstracting Geographic Information in a Data Rich World written by Dirk Burghardt and published by Springer. This book was released on 2014-07-08 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research in the field of automated generalisation has faced new challenges in recent years as a result of technological developments in web-based processing, new visualisation paradigms and access to very large volumes of multi-source data generated by sensors and humans. In these contexts, map generalisation needs to underpin ‘on-demand mapping’, a form of mapping that responds to individual user requirements in the thematic selection and visualisation of geographic information. It is this new impetus that drives the research of the ICA Commission on Generalisation and Multiple Representation (for example through its annual workshops, biannual tutorials and publications in international journals). This book has a coherent structure, each chapter focusing on core concepts and tasks in the map generalisation towards on-demand mapping. Each chapter presents a state-of-the-art review, together with case studies that illustrate the application of pertinent generalisation methodologies. The book addresses issues from data gathering to multi scaled outputs. Thus there are chapters devoted to defining user requirements in handling specifications, and in the application and evaluation of map generalisation algorithms. It explores the application of generalisation methodologies in the context of growing volumes of data and the increasing popularity of user generated content.
