"Albrecht's slim volume is an important contribution to users and teachers of geographic information systems. It is a distillation of the core functions available in contemporary workstation GIS systems, functions likely to become common on Web mapping systems like Google Earth and MS Virtual Earth. Well written and up-to-date, this book is an excellent complement to the voluminous documentation provided by software and solutions vendors." -CHOICE Key Concepts and Techniques in GIS is a concise overview of the fundamental ideas that inform Geographic Information Science. It provides detailed descriptions of the concepts and techniques that anyone using GIS software must fully understand to analyze spatial data.
