Preface 

   With ten years in the GIS business, I have learned how to communicate effectively with bosses, clients, other scientists, and the public by using maps as the printed or digital culmination of my analyses. I am close enough to the beginning of my career, when I was blindly going about printing maps with no clear purpose or sense of style (as many other entry‑level GIS professionals still do), to remember what it was like to make maps without a guidebook. Since then I have submitted hundreds of slides, report graphics, posters, and letter‑sized results maps to bosses, clients, conferences, and colleagues. I wish that a book like this had existed when I began my career. Through that recognized need, I began thinking about writing one myself. This book is the result of ten years of research and practice in map design. It aims to give you a big boost up the map design learning curve that I so painstakingly climbed.
