This book is an excellent reference text regarding the history and basics of GIS. It includes clear examples of concepts illustrating choices the geospatial professional must make in design and layout and how those choices aect a map product. The reader can literally see how decisions about line, color, shape, and other qualities will render a map that is the most useful and the most aesthetic. It also includes important information about the various v ways in which GIS data is obtained, how it is stored, and a great overview of GIS software.

I envision the book being used as a teaching tool, both in a formal setting and for self-learners. Additionally, for more experienced geospatial professionals, this book can be used in the initial ideation phase of creating a map, reminding us of the elements we need to consider and prioritize to meet the objectives for a particular map
