Geographic Information Metadata for Spatial Data Infrastructures
Author: Javier Nogueras-Iso
language: en
Publisher: Springer Science & Business Media
Release Date: 2005-03-30
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).

Spatial Data Infrastructures in Context
In the wake of the so-called information technology revolution, many stakeholders from the public and private sectors (including citizens) have indeed grown accustomed to the promise and usability of spatial data infrastructures (SDI) for data access, use, and sharing. With contributions from international experts, this book presents cutting edge Spatial Data Infrastructure (SDI) research on information technology, systems, and infrastructures that is theoretically-based and empirically supported. It examines the complexities involved in the establishments of SDIs in the Northern and Southern hemispheres and use of SDIs in a variety of cultural, societal, and institutional contexts. The focus is on urban and regional levels where socio-economic and environmental sustainability is realized.
