✦ Synopsis

This is a significantly revised and extended new edition of Michael Kennedy's acclaimed book.The Global Positioning System and GIS is a clear text and a guide to the use and integration of these powerful technologies, with each topic combining an overview with a step-by-step approach. The book now comes with a set of resources on a CD-ROM, including an instructor's guide, demonstration data and exercises. Many more sets of GIS data are provided with the sample GPS data. It is a straightforward introductory text for students and teachers on GIS/GPS courses. It is also a practical and introductory field manual for mapping science professionals, giving basic practical guidance, particularly to the integrated use of ESRI's GIS software with Trimble's GPS hardware.
