Georeferencing--relating info to geographic location--has been integrated into state-of-the-art info structures in a variety of methods. We use on-line companies to map our course from one position to a different; technology, company, and executive more and more use geographic info platforms (GIS) to carry and study information. so much georeferenced info searches utilizing modern-day details platforms are performed by means of textual content question. yet textual content searches for placenames fall short--when, for instance, a spot is understood by means of numerous names (or via none). furthermore, textual content searches do not conceal all assets of geographic facts; maps are characteristically accessed purely via specific indexes, submitting platforms, and business enterprise contacts; info from distant sensing pictures or aerial images is listed by means of geospatial position (mathematical coordinates resembling longitude and latitude). during this e-book, Linda Hill describes the merits of integrating placename-based and geospatial referencing, introducing an method of "unified georeferencing" that makes use of placename and geospatial referencing interchangeably throughout every kind of knowledge garage and retrieval systems.After a quick assessment of appropriate fabric from cognitive psychology on how people understand and reply to geographic house, Hill introduces the reader to uncomplicated information regarding geospatial details gadgets, recommendations of geospatial referencing, the position of gazetteer facts, the ways that geospatial referencing has been incorporated in metadata constructions, and strategies for the implementation of geographic details retrieval (GIR). Georeferencing could be a invaluable reference for librarians, archivists, medical facts managers, info managers, designers of on-line prone, and any info specialist who bargains with place-based details.

In information systems, some confusion is caused because the information object of different systems and communities is not at the same level of granularity. Giving some illustrative examples is probably the best way to explain why this is important. Libraries have traditionally treated the book, journal, or map as their information object, which they describe in a catalog record with the author or producer, the title, the publisher and date, and so on. Digital libraries do this as well but also recognize collections (a higher level of granularity) and chapters of books (a lower level of granularity) as information objects.
Granularity can be thought of as being a level of detail or a level in a hierarchy of object types. For example, an administrative hierarchy for 20 Chapter 1 named geographic places will have the nation/country level, a state or province level, a county or parish level, and so forth. , granularity) that best suits its purposes. Geographic information systems (GIS) typically consider individual features and data points as their information objects; this fine level of granularity supports analysis, visualization, conflation, and similar activities.
In natural language, we talk about lakes, ponds, rivers, streams, reservoirs, oceans, and seas and, most of the time, avoid being precise in our classification of exactly what we mean by these terms. The water body one person calls a pond may be equivalent in size to what someone else calls a lake. We may not consciously consider the difference between a reservoir and a naturally formed lake when thinking in recreational terms where both function as “lakes” for boating, fishing, and so on, but the difference between human-made and natural will be recognized in other circumstances.
