Exploring Geographic Information Systems

Geographic Information Systems (GIS) is the organized activity by which people:measure aspects of geographic phenomena and processesrepresent these measurements, usually in the form of a computer database, to emphasize spatial themes, entities, and relationshipsoperate upon these representations to produce more measurements, and to discover new relationships by integrating disparate sources; andtransform these representations to conform to other frameworks of entities and relationships.
These activities reflect the larger context, such as institutions and cultures, in which these people carry out their work. In turn, the GIS may influence these structures.
This text provides the comprehensive coverage you will need to master this powerful new technology.
