Georeferencing—relating information to geographic location—has been incorporated into today's information systems in various ways. We use online services to map our route from one place to another; science, business, and government increasingly use geographic information systems (GIS) to hold and analyze data. Most georeferenced information searches using today's information systems are done by text query. But text searches for placenames fall short—when, for example, a place is known by several names (or by none). In addition, text searches don't cover all sources of geographic data; maps are traditionally accessed only through special indexes, filing systems, and agency contacts; data from remote sensing images or aerial photography is indexed by geospatial location (mathematical coordinates such as longitude and latitude). In this book, Linda Hill describes the advantages of integrating placename-based and geospatial referencing, introducing an approach to "unified georeferencing" that uses placename and geospatial referencing interchangeably across all types of information storage and retrieval systems.
After a brief overview of relevant material from cognitive psychology on how humans perceive and respond to geographic space, Hill introduces the reader to basic information about geospatial information objects, concepts of geospatial referencing, the role of gazetteer data, the ways in which geospatial referencing has been included in metadata structures, and methods for the implementation of geographic information retrieval (GIR). Georeferencing will be a valuable reference for librarians, archivists, scientific data managers, information managers, designers of online services, and any information professional who deals with place-based information.
About the Author
Linda L. Hill is Specialist, Department of Geography, University of California, Santa Barbara (retired).
"Should be on the shelf of every humanist scholar who creates or manages databases, and every information professional who deals with digital resources for the humanities.", Stuart E. Dunn, Literary and Linguistic Computing Advance Access
"The book provides a very useful primer for those beginning to design courses in the subject and is likely to become a classic in its field.", T. D. Wilson, Information Research
"Linda Hill, one of the planet's authorities on the subject of attaching information to place, has produced the definitive work on georeferencing. Organized, written, and illustrated with great clarity, her book is an indispensable reference for anyone seeking to organize and access content by geography."
Allen Carroll, Chief Cartographer, National Geographic Society
"This book is a valuable contribution to the growing literature on geographic information retrieval, and deserves a place on the shelf of anyone working in GIR or geographically based digital libraries."
Ray R. Larson, School of Information, University of California, Berkeley
"With Georeferencing, Linda Hill caps a distinguished career with a book that will become a benchmark for future studies of the topic. Within the Semantic Web framework, rigorous georeferencing will necessarily be a first-order service across most domains of knowledge. This is a major contribution to the entire digital-library community."
