The widely varying application fields of Geographic Information Systems (GIS) have meant that much of the GIS literature is scattered through the journals and technical reports of numerous disciplines. These sources are not always easily accessible, especially to the newcomer to the field. This book assembles a balanced sample of written works covering important aspects of the basic principles of GIS and selected examples of current applications. The principles and methods of analysis illustrated will have lasting value. The book is intended as a supplementary reader for use in introductory, upper-division or graduate-level courses on GIS, as well as for practising professionals. It is divided into five major sections: • What is a Geographic Information System?. • Examples of practical applications. • Operations and problems of building a database. • GIS internals - data representation and analysis techniques. • Design and evaluation of GIS.
