The hard part of problem solving using GIS analysis is the selection of the proper tools. David Verbyla has produced the only practical guide for solving geo-spatial problems which is independent of specific GIS software and hardware. It will teach you how GIS tools work, and how you can use them to solve problems in both vector and grid GIS worlds. You can test your problem solving abilities by trying the more than eighty GIS problems (and solutions) presented in this book. If you want to learn how GIS works, and what kinds of problems you can solve using it, this book is for you.
