Geographic Information Systems: An Introduction represents a timely new resource for students and professionals alike. The authors' main objective is to emphasize data integration as a philosophical basis for modern GIS, wherein a geographic information system is the appropriate tool for integrating the technologies used in gathering, analyzing, and assessing spatial data. The book begins with an introduction to the vocabulary, history, and essential components of geographic information systems. Following is an exploration of the five important parts of a GIS: data acquisition, preprocessing, database management, analysis and manipulation, and producing the final output. The later chapters introduce practical applications ranging from the design and management of large facilities to research on the global carbon cycle. A final chapter examines future trends and research developments in the held of geographic information systems. eng
