GIS are critical for effective resource management, and have been applied across a wide range of science, business, and government projects.This book provides an introduction to the theory and application of GIS. It is written for use in a first-year GIS class and as a reference for the GIS practitioner. This seventh edition balances theoretical and practical material, so that people may apply knowledge of GIS in the solution of real-world problems.
