The World Wide Web presents many new, exciting prospects for geographic information systems, but also numerous technical, practical and organizational challenges. Users no longer require specialized and expensive hardware, software and data, and they can access a GIS readily from almost anywhere, using off-the-shelf browser software. An online GIS removes the need to collate all the necessary elements in a single database. Instead it has the potential to seamlessly combine datasets that are stored on many different servers and maintained by many different organizations. However, to realize this potential it is crucial to develop appropriate standards and protocols. Such problems belong to the realm of "spatial metadata" which forms the basis of this book. The book covers the principles, techniques and standards for online GIS, including online spatial information and data warehousing. It examines the idea of metadata and outlines why it is important today, especially in the context of online information. It explains the underlying methodologies, including relevant standards, and the tools and skills needed to manage metadata. Finally, the subject is placed in the context of global GIS: putting data online; creating metadata; creating virtual data warehouses; geographical agents, and spatial data mining.

Implement Your Own Applications Using Online GIS An in-depth study detailing the online applications of geographic information systems (GIS), Online GIS and Spatial Metadata, Second Edition outlines how GIS data are published, organized, accessed, searched, maintained, purchased, and processed over the web. This latest work describes how the internet has become a platform for the delivery and integration of geographic information. It highlights the growth that has taken place since the first edition and includes new chapters on popular XML formats used in online GIS, SDI Metadata Portals, Mobile GIS and Location-Based services. It also updates metadata standards and explains how metadata links it all together. Designed To Help Non-Technical Readers Understand Technical Issues The book provides a brief overview of the basic technology of online GIS before introducing the technical methods used to develop and implement GIS on the web. It includes an introduction to the protocols and standards now in use online and provides technical background and real-world examples of scripts, markup, and other elements that make this technology work. Expanding on the previous edition, the book offers a global perspective of online GIS, contains links and references to online resources, and includes future directions, applications, and trends. Reviewing major advances that have occurred over the past decade, this seminal work: Discusses the detail of four XML-based standards now in common use for Online GIS and spatial metadata Outlines the nature of Information Networks, systems in which information is distributed across many different sites Examines the conceptual framework of metadata, by studying the RDF and similar standards for the Web Describes several metadata standards in use around the world for spatial metadata Provides current examples of SDI metadata portals, catalogues, and clearinghouses Looks at ways in which distributed information can be built into data warehouses, and introduces basic ideas in data mining

Metadata and semantic research is a growing complex ecosystem of conceptual, theoretical, methodological, and technological frameworks, offering innovative computational solutions in the design and development of computer-based systems. Within this perspective, researchers working in the area need to further develop and integrate a broad range of methods, results, and solutions coming from different areas. MTSR has been designed as a forum allowing researchers to present and discuss specialized results as general contributions to the field. This volume collects the papers selected for presentation at the 4th International Conference on Metadata and Semantic Research (MTSR 2010), held in Alcala de Henares––a world heritage city and birthplace of Miguel de Cervantes––at the University of Alcala (October 20–22, 2010). The first MTSR conference was held online in 2005, followed by two more editions: in Corfu (2007) and in Milan (2009). The experience acquired during the past five years, and the warm welcome of MTSR by the research community, encouraged us to organize this new edition of the series, and turn it into a yearly event. According to the number and quality of the contributions submitted for revision, our 2010 effort was again a considerable success.

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

The book is a new comprehensive textbook about creating and publishing geoinformation metadata. It is a compendium of knowledge about geoinformation metadata in INSPIRE Directive and Spatial Information Infrastructures. It contains the knowledge necessary to understand prior to the creation of geoinformation metadata. Metadata – “data about data” - describe the layers of spatial data (data series, services) responding to the questions: what?, why?, when?, who?, how? and where? Geoinformation metadata allows for exact search of the spatial data according to given criteria, regardless of where this data is located. On 15 May 2007 the EU Directive 2007/2/EC came into force establishing Infrastructure for Spatial Information in Europe - INSPIRE. The proper functioning of the infrastructure for spatial information would not be possible without the metadata.

Cloud Computing in Ocean and Atmospheric Sciences provides the latest information on this relatively new platform for scientific computing, which has great possibilities and challenges, including pricing and deployments costs and applications that are often presented as primarily business oriented. In addition, scientific users may be very familiar with these types of models and applications, but relatively unfamiliar with the intricacies of the hardware platforms they use. The book provides a range of practical examples of cloud applications that are written to be accessible to practitioners, researchers, and students in affiliated fields. By providing general information on the use of the cloud for oceanographic and atmospheric computing, as well as examples of specific applications, this book encourages and educates potential users of the cloud. The chapters provide an introduction to the practical aspects of deploying in the cloud, also providing examples of workflows and techniques that can be reused in new projects. Provides real examples that help new users quickly understand the cloud and provide guidance for new projects Presents proof of the usability of the techniques and a clear path to adoption of the techniques by other researchers Includes real research and development examples that are ideal for cloud computing adopters in ocean and atmospheric domains
