Beyond Mapping: Concepts, Algorithms, and Issues in GIS

This book really made me think about GIS analysis in a new way. This book covers topics such as thinking of maps "map-ematically", distance across a terrain rather than just straight lines, slope and aspect as mathematical surface derivatives (as in calculus), and much, much more. If you are serious about GIS and spatial modeling, this book is a must read. Berry has a way of looking a GIS analysis that is different than anybody else I have read or listened to. And his presentation style is exciting and fresh. I have seen Berry in live presentations twice and he never fails to disappoint for content or style.
