Las infraestructuras de datos espaciales son grandes sistemas de información distribuidos en Internet, basados en estándares abiertos y que permiten compartir y usar datos cuya localización es importante, como carreteras, imágenes de satélite y aéreas, negocios y lugares de interés turístico, mapas de ruido y contaminación, callejeros o datos demográficos. Este libro presenta una aproximación basada en arquitecturas de sistemas de información distribuidos para especificar y documentar infraestructuras de datos espaciales y facilitar así su desarrollo y análisis.
Metadata play a fundamental role in both DLs and SDIs. Commonly defined as "structured data about data" or "data which describe attributes of a resource" or, more simply, "information about data", it is an essential requirement for locating and evaluating available data. Therefore, this book focuses on the study of different metadata aspects, which contribute to a more efficient use of DLs and SDIs. The three main issues addressed are: the management of nested collections of resources, the interoperability between metadata schemas, and the integration of information retrieval techniques to the discovery services of geographic data catalogs (contributing in this way to avoid metadata content heterogeneity).
This book constitutes the refereed proceedings of the 5th International Workshop on Web and Wireless Geographical Information Systems, W2GIS 2005, held in Lausanne, Switzerland in December 2005. The 25 revised full papers presented were carefully reviewed and selected from 70 submissions and cover a wide range of topics from web semantic and personalization, contextual representation and mapping to querying in mobile environment, to mobile networks and location-based services. The papers are organized in topical sections on mobile GIS and LBS, mapping and representation issues in Web and mobile GIS, mobile networks, querying in a mobile environment, context and personalization issues in Web and mobile GIS, Web GIS, and modeling for Web and mobile GIS.
For the sixth consecutive year, the AGILE conference promoted the publication a book collecting high-level scientific contributions from unpublished fundamental scientific research. The papers published in the AGILE 2012 LNG&C volume contribute substantially to Geographical Information Science developments and to the success of the 15th AGILE conference (Avignon, France, 24-27April, 2012) under the title ‘Bridging the Geographic Information Sciences’. This year’s conference emphasizes that geoinformation science, geomatics and spatial analysis are fields in which different disciplines, epistemologies and scientific cultures meet. Indeed, the scientific articles published in this volume...

This book constitutes the thoroughly refereed joint post-proceedings of the 10th Conference of the Spanish Association for Artificial Intelligence, CAEPIA 2003, and the 5th Conference on Technology Transfer, TTIA 2003, held in San Sebastin, Spain, in November 2003. The 66 revised full papers presented together with one invited paper were carefully selected during two rounds of reviewing and improvement from an initial total of 214 submissions. The papers span the entire spectrum of artificial intelligence and advanced applications in various fields.
This book constitutes the proceedings of the 11th International Symposium on Web and Wireless Geographical Information Systems, W2GIS 2012, held in Naples, Italy, in April 2012. The 13 full and 4 short papers presented in this book were carefully reviewed and selected from 32 submissions. The papers are organized in topical sections named: 3D and multimodal spatial interaction; positioning; spatial human-computer interaction; trajectory analysis; geo semantics; and sensor networks.
