This book describes the development of geographic technology from maps that simply tell us "Where is what?" to systems that help us decide "So what?" It encourages new understandings of mapped data, data analysis procedures and the uses of maps, fostering an appreciation of GIS as an effective analytical tool in many complex processes. A disk containing four-color graphics including charts and maps is also available. Includes recommended readings and a section devoted to formulae used in GIS. Compiles international GIS institutions and lists contact details and information on each.
